A new species of Xylaria is described based on morphological characters of both sexual and asexual morphs, and molecular data based on nuclear rDNA internal transcribed spacer, α-actin, β-tubulin and RNA polymerase subunit II sequences. Xylaria aurantiorubroguttata is characterized by the presence of both upright, cylindrical, long-stipitate and globose to subglobose, short-stipitate stromata, immature stromatal stages producing at first orange and then red drops, and ascospores with a slightly oblique, straight half spore-length germ slit. We provide also new morphological descriptions for X. haemorrhoidalis (holotype) and X. anisopleura (isosyntype), two Xylaria species belonging to X. polymorpha complex together with X. aurantiorubroguttata.

Freshwater fungi exhibit a remarkable diversity and are commonly found on submerged wood, freshwater insects, herbaceous materials, sediments, leaves, foam, and living plants. Sordariomycetes in the Ascomycota is the most frequently reported group in freshwater environments. Three samples of submerged decaying wood and twigs samples were collected and examined during in this study from freshwater habitats in Yunnan and Sichuan provinces in China. Detailed morphological studies, complemented by phylogenetic analyses based on ITS, LSU, SSU, RPB2 and TEF1-α sequence data, revealed them to be three hitherto known species, namely Acrogenospora thailandica, Cancellidium cinereum and Chloridium humicola. Of these, Acrogenospora thailandica is a new geographical record for China. Chloridium humicola is also reported for the first time in China which enhances the geographical and host distribution of this species, providing new insights into its ecological preferences. Cancellidium cinereum is reported as an additional provincial record from China, contributing to our knowledge of its regional distribution. All three species, reported in their asexual state, are illustrated with detailed morphological descriptions and phylogenetic analyses. In addition, we also provide a new host record of the saprobic species Isthmolongispora quadricellularia in hyphomycetous asexual state on decaying wood for the first time in a terrestrial habitat.

Stropharia rugosoannulata is an important edible mushroom in China, but green mold disease has caused significant production and economic losses. In this study, two new pathogens Trichoderma strophariensis and T. viridistromatis were identified as the causal agents of this disease. During October-November 2023, six strains of the fungal pathogen were isolated from infected fruiting bodies of S. rugosoannulata and identified based on morphological characteristics and molecular phylogenetic analyses of internal transcribed spacer (nrITS), the second largest RNA polymerase II subunit (rpb2) and the partial translation elongation factor 1-alpha (tef1-α) region. The representative isolates of the pathogenic green mold Trichoderma species were used to perform a pathogenicity test with spore suspensions, resulting in symptoms similar to those observed in the cultivated field. The same pathogens were successfully re-isolated, thereby fulfilling Koch's postulates. Detailed morphological descriptions, illustrations, culture characteristics, and comparisons with morphologically similar and closely related species are provided. [ABSTRACT FROM AUTHOR]

Based on their morphological characteristics and molecular markers (ITS and LSU), this study describes three new species of mytilinidioid fungi: Ericboehmia mexicana of the family Hysteriaceae of the order Hysteriales and Lophium pinicola and Mytilinidion mexicanum of the family Mytilinidiaceae of the order Mytilinidiales. The first species grows on Liquidambar styracyphlua, the second species grows on Pinus patula, and the third species grows on Acacia californica subsp. pringlei. The specimens studied were deposited in the ENCB Herbarium. [ABSTRACT FROM AUTHOR]

Tuber magnatum Picco, the Italian white truffle mushroom recorded for the first time in Türkiye, is a rare and economically valuable mushroom. Samples were collected from Sakarya province during field studies in 2024. The samples were identified as T. magnatum according to their macro- and microscopic features. To make molecular confirmation of the species, the samples' ITS1 and ITS4 gene regions were analysed and registered in Genbank with the number PP239641. The sample showed 100% compatibility with other T. magnatum accessions in Genbank. The distributions of Tuber species in Türkiye were given, and their taxonomic features were compared.

A meticulous morphological study of the genus Minimelanolocus and related genera reveals that several species within the genus are not congeneric. As a result, two new genera, Acuminavicula and Zelofuscophialis, are proposed to accommodate Minimelanolocus chimonanthi and M. bicolorata, respectively. Additionally, a new species, M. eucalypti, is proposed. Seven species of Minimelanolocus are reassigned to the genera Kylindria, Nigrolentilocus, Pyriculariopsis, Repetophragma and Thysanorea. Two synonyms are proposed for Belemnospora verruculosa and Repetophragma dennisii. The new combination Kylindria yunnanensis is suggested based on morphological and phylogenetic analysis. A synoptic table and illustrations of conidia of accepted species are provided. [ABSTRACT FROM AUTHOR]

A lichenicolous species, Calicium ramboldiicola , growing on Ramboldia elabens is described. In phylogenetic analyses with 22 Calicium taxa, based on 121 sequences from five DNA regions (mtSSU, Mcm7 , nuITS, nuLSU, β-tubulin), the new species formed a strongly supported clade with C. abietinum and C. verrucosum. Although the ascomata of the new species resemble miniatures of those of C. abietinum , no morphological synapomorphies for this clade were found. Calicium ramboldiicola is known from boreal and hemiboreal areas of northern Europe and north-eastern North America. It is the second known lichenicolous species of Calicium and the first found on a lichen in the Lecanorales. [ABSTRACT FROM AUTHOR]

It is similar to Candelariella citrina but differs in having ascospores without attenuated ends and smaller squamules. Candelariella citrina is excluded from the lichen flora of Russia. A worldwide key to all known Candelariella species with 8-spored asci, including 41 names, is provided. [ABSTRACT FROM AUTHOR]

Apple tree canker is a serious disease caused by species of Cytospora. Xinjiang Uygur Autonomous Region is one of the most important apple-producing areas in China. However, losses due to apple Cytospora canker have seriously damaged the apple industry and affected the economic development of the apple growers in this region. In this study, we used morphological characteristics combined with multilocus phylogenetic analyses of the ITS , act , rpb2 , tef1 and tub2 loci to identify isolates from apple (Malus domestica) and wild apple (M. sieversii). As a result, C. hippophaopsis sp. nov. from M. sieversii and C. shawanensis sp. nov. from M. domestica were discovered and proposed herein. Pathogenicity tests were further conducted on 13 varieties of apple and wild apple, which confirmed C. hippophaopsis and C. shawanensis as canker pathogens. Meanwhile, C. hippophaopsis is generally more aggressive than C. shawanensis on the tested varieties of apple and wild apple. [ABSTRACT FROM AUTHOR]

Six collections of ascomycetes were obtained from samples collected from dead branches and leaves of Juglans regia in Guizhou and Yunnan provinces, China. By incorporating multigene phylogenetic analysis (ITS , LSU , rpb2 , SSU , tef1-α , tub2) supplemented by morphological data, we establish two novel species, namely Helminthosporium guizhouense and Nigrospora yunnanensis. In morphology, H. guizhouense can be distinguished from H. caespitosum by its narrower conidia (13–16 µm vs. 27.3–35.5 µm), and N. yunnanensis is characterized by black, globose conidia (16.2 × 14.4 µm). The phylogenetic results further substantiated them as novel taxa. The present study contributes to our comprehension of the range of fungi found in Juglans regia, thereby expanding our knowledge of the diversity of fungi within this host. [ABSTRACT FROM AUTHOR]

During our investigation of microfungi on grasslands in Yunnan Province, China, three new fungal taxa associated with grasses were collected. Morphological observations and phylogenetic analyses of the combined SSU, LSU, ITS, tef1-α, and rpb2 loci based on maximum likelihood and Bayesian inference were used to reveal the taxonomic placement of these fungal taxa. This study introduces Parastagonospora yunnanensis, Para. zhaotongensis, Phaeoseptoriella poaceicola. Parastagonospora yunnanensis is characterized by ampulliform or globose to subglobose conidiogenous cells, with conidia that are cylindrical to subcylindrical, 0–1-septate, rounded at the apex and slightly truncate at the base. Parastagonospora zhaotongensis features similar globose to subglobose conidiogenous cells but with 0–3-septate, cylindrical to subcylindrical conidia. Phaeoseptoriella poaceicola is distinguished by its globose to subglobose conidiogenous cells and phragmosporous conidia that are initially hyaline, turn pale yellowish at maturity, and are 7-septate, cylindrical to subcylindrical, either straight or slightly curved. These discoveries underscore the significance of exploring and accurately identifying fungal taxa within Ascomycota, highlighting the species richness and potential for new species discoveries in grass-based habitats. The findings from this study expand our understanding of the taxonomy and phylogeny of grassland-associated Ascomycota, providing a foundation for further ecological and taxonomic studies of these fungi within their natural environments.

We studied the culturable fungal community recovered from deep marine sediments in the maritime Antarctic, and assessed their capabilities to produce exoenzymes, emulsifiers and metabolites with phytotoxic activity. Sixty-eight Ascomycota fungal isolates were recovered and identified. The most abundant taxon recovered was the yeast Meyerozyma guilliermondii, followed by the filamentous fungi Penicillium chrysogenum, P. cf. palitans, Pseudeurotium cf. bakeri, Thelebolus balaustiformis, Antarctomyces psychrotrophicus and Cladosporium sp. Diversity indices displayed low values overall, with the highest values obtained at shallow depth, decreasing to the deepest location sampled. Only M. guilliermondii and P. cf. palitans were detected in the sediments at all depths sampled, and were the most abundant taxa at all sample sites. The most abundant enzymes detected were proteases, followed by invertases, cellulases, lipases, carrageenases, agarases, pectinases and esterases. Four isolates showed good biosurfactant activity, particularly the endemic species A. psychrotrophicus. Twenty-four isolates of P. cf. palitans displayed strong phytotoxic activities against the models Lactuca sativa and Allium schoenoprasum. The cultivable fungi recovered demonstrated good biosynthetic activity in the production of hydrolytic exoenzymes, biosurfactant molecules and metabolites with phytotoxic activity, reinforcing the importance of documenting the taxonomic, ecological and biotechnological properties of fungi present in deep oceanic sediments of the Southern Ocean.

Members of the fungal order Diaporthales are sac fungi that include plant pathogens (the notorious chestnut blight fungus), as well as saprobes and endophytes, and are capable of colonizing a wide variety of substrates in different ecosystems, habitats, and hosts worldwide. However, many Diaporthales species remain unidentified, and various inconsistencies within its taxonomic category remain to be resolved. Here, we aimed to identify and classify new species of Diaporthales by using combined morphological and molecular characterization and coupling this information to expand our current phylogenetic understanding of this order. Fungal samples were obtained from dead branches and diseasedleaves of Camellia (Theaceae) and Castanopsis (Fagaceae) in Fujian Province, China. Based on morphological characteristics and molecular phylogenetic analyses derived from the combined nucleotide sequences of loci of the internal transcribed spacer regions with the intervening 5.8S nrRNA gene (ITS), the 28S large subunit of nuclear ribosomal RNA gene (LSU), the translation elongation factor 1-α gene (tef1), the partial beta-tubulin gene (tub2), and partial RNA polymerase II second-largest subunit gene (rpb2), three new species of Diaporthales were identified and characterized. They are as follows: Chrysofolia camelliae sp. nov., Dendrostoma castanopsidis sp. nov., and Pseudoplagiostoma wuyishanense sp. nov. They are described and illustrated. This study extends our understanding of species diversity within the Diaporthales. [ABSTRACT FROM AUTHOR]

Two new species of the genus Lecidella, one with a North American-maritime Antarctic distribution and one with a so far exclusively southern South American-maritime Antarctic distribution, are described using molecular and morphological tools. Lecidella ayazii is a species growing on soil and also on mosses and has so far been found on the Antarctic Peninsula, as well as in the alpine areas of the La Sal Mountains, Utah, USA and in the Kivalliq Region (Nunavut) in the north of Canada, whereas L. drakensis occurs mainly on siliceous rocks, rarely on mosses, and has been recorded on both sides of the Drake Passage in southern Patagonia and the Antarctic Peninsula. Phylogenetic analysis of the nrITS sequence data shows that both species belong in the L. elaeochroma clade, each forming a highly supported and distinct group. Furthermore, they also differ in morphological and chemical characters from the species described so far in this clade. In addition, five further accessions were recorded from the maritime Antarctic, which were placed in the cosmopolitan and heterogeneous L. stigmatea clade, of which one could be assigned to the bipolar species L. siplei.

In Morocco, there are many different types of desert truffles, including Terfezia, Tirmania, Delastria, Picoa, and Tuber. The Maamora Forest, Doukkala-Abda Sahel, northeast of Morocco, and the Moroccan Sahara are the four truffle regions where the geographical distribution of these ascomycetes has been noted most frequently. In addition to being a great source of protein, amino acids, carbon hydrates, and fiber, desert truffles are also regarded as a valuable source of antibiotic alternatives for pathogenic bacteria that are resistant to antibiotics. Due to the widespread appreciation of truffles, we could use these resources to develop local populations, especially in truffle-producing regions. The biodiversity of desert truffles in Morocco and other Maghreb countries is one of the characteristics of truffles that are briefly discussed in this paper review. Ecology, biology, geographical spread, and final considerations include the mycorrhizal association of truffles, biochemistry, and physiology. [ABSTRACT FROM AUTHOR]

The Saladas de Sástago-Bujaraloz is an endorheic and arheic complex of lagoons located in the Ebro Basin and protected by the Ramsar Convention on Wetlands. Due to the semi-arid climate of the region and the high salinity of their waters, these lagoons constitute an extreme environment. We surveyed the biodiversity of salt-tolerant and halophilic fungi residents of the Laguna de Pito, a lagoon belonging to this complex. Therefore, we collected several samples of water, sediments, and soil of the periphery. Throughout the study, we isolated 21 fungal species, including a strain morphologically related to the family Microascaceae. However, this strain did not morphologically match any of genera within this family. After an in-depth morphological characterization and phylogenetic analysis using a concatenated sequence dataset of four phylogenetically informative molecular markers (the internal transcribed spacer region (ITS) of the nuclear ribosomal DNA (nrDNA); the D1-D2 domains of the 28S gene of the nuclear ribosomal RNA (LSU); and a fragment of the translation elongation factor 1-alpha (EF-1α) and the β-tubulin (tub2) genes), we established the new genus Dactyliodendromyces, with Dactyliodendromyces holomorphus as its species. Additionally, as a result of our taxonomic study, we reclassified the paraphyletic genus Wardomyces into three different genera: Wardomyces sensu stricto, Parawardomyces gen. nov., and Pseudowardomyces gen. nov., with Parawardomyces ovalis (formerly Wardomyces ovalis) and Pseudowardomyces humicola (formerly Wardomyces humicola) as the type species of their respective genera. Furthermore, we propose new combinations, including Parawardomyces giganteus (formerly Wardomyces giganteus) and Pseudowardomyces pulvinatus (formerly Wardomyces pulvinatus). [ABSTRACT FROM AUTHOR]

The tropical areas in southern and south-western Yunnan are rich in fungal diversity. Additionally, the diversity of seed flora in Yunnan Province is higher than in other regions in China and the abundant endemic species of woody plants provide favourable substrates for fungi. Rubber plantations in Yunnan Province are distributed over a large area, especially in Xishuangbanna. During a survey of rubber-associated fungi in Yunnan Province, China, dead rubber branches with fungal fruiting bodies were collected. Morphological characteristics and multigene phylogenetic analyses (ITS, LSU, SSU, rpb2 and tef1-α) revealed four distinct new species, described herein as Melomastia puerensis, Nigrograna lincangensis, Pseudochaetosphaeronema lincangensis and Pseudochaetosphaeronema xishuangbannaensis. Detailed descriptions, illustrations and phylogenetic trees are provided to show the taxonomic placements of these new species. [ABSTRACT FROM AUTHOR]

Wickerhamomyces is a well-known genus of the family Wickerhamomycetaceae in the class Ascomycetes. These fungi can survive in a variety of substrates and environments and perform many valuable roles in both industrial processes and the natural ecosystems. During our investigation of yeast diversity associated with plant materials, 53 Wickerhamomyces isolates were obtained from rotting wood and plant leaves collected in Fujian, Guizhou, Henan, and Yunnan Provinces of China. Isolates were identified as 14 Wickerhamomyces species, including 1 species known previously to occur in China (W. anomalus), 9 new record species in China (W. arborarius, W. ciferrii, W. edaphicus, W. lynferdii, W. pijperi, W. subpelliculosa, W. xylosica, W. strasburgensis, and W. sydowiorum), and 4 novel species (W. guiyangensis sp. nov., W. paramyanmarensis sp. nov., W. quanzhouensis sp. nov., and W. phyllophilus sp. nov.). This study presents a detailed account of these new species, illustrating their morphology and analyzing their phylogenetic relationships with other Wickerhamomyces species. Our study is the first comprehensive study on Wickerhamomyces species associated with plant materials from tropical and subtropical China. The results of this study update our understanding of the phylogenetic relationships, systematics, and ecology of Wickerhamomyces. [ABSTRACT FROM AUTHOR]

Loxospora is a genus of crustose lichens containing 13 accepted species that can be separated into two groups, based on differences in secondary chemistry that correlate with differences in characters of the sexual reproductive structures (asci and ascospores). Molecular phylogenetic analyses recovered these groups as monophyletic and support their recognition as distinct genera that differ in phenotypic characters. Species containing 2'-O-methylperlatolic acid are transferred to the new genus, Chicitaea Guzow-Krzem., Kukwa & Lendemer and four new combinations are proposed: C. assateaguensis (Lendemer) Guzow-Krzem., Kukwa & Lendemer, C. confusa (Lendemer) Guzow-Krzem., Kukwa & Lendemer, C. cristinae (Guzow-Krzem., Łubek, Kubiak & Kukwa) Guzow-Krzem., Kukwa & Lendemer and C. lecanoriformis (Lumbsch, A. W. Archer & Elix) Guzow-Krzem., Kukwa & Lendemer. The remaining species produce thamnolic acid and represent Loxospora s.str. Haplotype analyses recovered sequences of L. elatina in two distinct groups, one corresponding to L. elatina s.str. and one to Pertusaria chloropolia, the latter being resurrected from synonymy of L. elatina and, thus, requiring the combination, L. chloropolia (Erichsen) Ptach-Styn, Guzow-Krzem., Tønsberg & Kukwa. Sequences of L. ochrophaea were found to be intermixed within the otherwise monophyletic L. elatina s.str. These two taxa, which differ in contrasting reproductive mode and overall geographic distributions, are maintained as distinct, pending further studies with additional molecular loci. Lectotypes are selected for Lecanora elatina, Pertusaria chloropolia and P. chloropolia f. cana. The latter is a synonym of Loxospora chloropolia.

The lichenised fungal genus Pyrenula is a very common crustose lichen element in tropical to subtropical forests, but little research has been done on this genus in China. During our study on Pyrenula in China, based on morphological characteristics, chemical traits and molecular phylogenetic analysis (ITS and nuLSU), three new 3-septate species with red or orange oil in over-mature ascospores were found: Pyrenula inspersa sp. nov., P. thailandicoides sp. nov. and P. apiculata sp. nov. Compared to the known 3-septate species of Pyrenula with red or orange oil, P. inspersa is characterised by the inspersed hamathecium; P. thailandicoides is characterised by the IKI+ red hamathecium and the existence of an unknown lichen substance; and P. apiculata is characterised by the absence of endospore layers in the spore tips and the absence of pseudocyphellae. It is reported for the first time that the presence of a gelatinous halo around the ascospores of Pyrenula is common. A word key for the Pyrenula species with red or orange oil in over-mature ascospores is provided. [ABSTRACT FROM AUTHOR]

Whilst conducting surveys of lignicolous microfungi in Yunnan Province, we collected a large number of taxa that resemble Montagnula (Didymosphaeriaceae, Pleosporales). Our phylogenetic study on Montagnula involved analysing sequence data from ribosomal RNA genes (nc18S, nc28S, ITS) and protein-coding genes (rpb2, tef1-a). We present a biphasic approach (morphological and molecular phylogenetic evidence) that supports the recognition of four new species in Montagnula viz., M. lijiangensis, M. menglaensis, M. shangrilana and M. thevetiae. The global diversity of Montagnula is also inferred from metabarcoding data and published records based on field observations. Metabarcoding data from GlobalFungi and field observations provided insights into the global diversity and distribution patterns of Montagnula. Studies conducted in Asia, Australia, Europe, and North America revealed a concentration of Montagnula species, suggesting regional variations in ecological preferences and distribution. Montagnula species were found on various substrates, with sediments yielding a high number of sequences. Poaceae emerged as a significant contributor, indicating a potential association between Montagnula species and grasses. Culture-based investigations from previously published data revealed Montagnula species associations with 105 plant genera (in 45 plant families), across 55 countries, highlighting their wide ecological range and adaptability. This study enhances our understanding of the taxonomy, distribution, and ecological preferences of Montagnula species. It emphasizes their role in the decomposition of organic matter in grasslands and savannah systems and suggests further investigation into their functional roles in ecosystem processes. The global distribution patterns and ecological interactions of Montagnula species underscore the need for continued research and conservation efforts. [ABSTRACT FROM AUTHOR]

Circinaria russus sp. nov. is described based on morpho–anatomical and phylogenetic analysis. The novel species is characterized by its reddish brown thallus, absence of marginal lobes, taller hymenium 175–190 µm, and larger ascospores 22–32 × 15–20 than the similar taxon Circinaria tortuosa. A phylogenetic analysis, based on ITS nrDNA sequencing and ML analysis, supported the separation of the novel species. Complete description and a comparative analysis with related Circinaria species are provided. [ABSTRACT FROM AUTHOR]

Recent lichenological fieldwork in the Czech Republic resulted in the discovery of two previously unrecognized entities in the genus Psilolechia which are described below as new species: the saxicolous P. cretacea and the lignicolous P. torii . Both taxa regularly produce a hyphomycetous anamorph in the form of erect, elongate conidiogenous cells on the thallus surface, and both contain unidentified specific secondary metabolites. The placement of the two new species within the genus is primarily based on morphology and chemistry. In addition, three barcodes were received for P. cretacea (ITS, mtSSU) and P. torii (ITS). A key to the five species of Psilolechia currently known from Europe is included.

Toninia pakistanica sp. nov. is described from Darel Valley, Gilgit Baltistan, Pakistan. Its place within the genus Toninia A. Massal. was validated by a comparative morpho-anatomical investigation and ITS based molecular studies. The taxon is characterized by dark brown lobate squamules, epruinose to weakly pruinose with dark olive to black thallus, densely pruinose upper surface, more thicker epinecral layer 60 µm, 25–45 µm thick grey to blackish grey lower cortex and with the absence of apothecia and secondary metabolites. Its positioning in a separate branch in the phylogenetic tree also makes it distinct from the other known species. Phylogenetic analysis based on ITS-nrDNA sequencing placed our species relative to Toninia cinereovirens (Schaer.) A. Massal. Kiliasia nordlandica (Th. Fr.) Kistenich, Timdal, Bendiksby & S. Ekman is included and reported as new record to Pakistan. [ABSTRACT FROM AUTHOR]

Estuaries are considered promising habitats for the presence of marine and freshwater fungal species because of their favourable environmental conditions. Janhula paraensis sp. nov. was found on decaying wood collected in the intertidal zone in fluvial beaches of Mosqueiro Island, Pará, Brazil. The new species differs from others in the genus by its morphology including dark brown ascospores, with thick and dark bands at septum when mature, a hyaline cap at both ends and the absence of a mucilaginous sheath. It was not possible to obtain molecular data for the new species. New records of Boerlagiomyces websteri, Corollospora pseudopulchella, Falciformispora lignatilis, and Savoryella lignicola for South America and Annulusmagnus triseptatus for Brazil are reported. Morphological descriptions and illustrations are presented for all species. [ABSTRACT FROM AUTHOR]

The genus Parvoplaca is extended with four new species: P. candanii from Antarctica, P. lamprocarpa from Alaska, and P. macroborealis and P. tenebrosa from Oregon. Collections identified as P. tiroliensis are shown to form two independent clades when DNA was analyzed, but it is currently not clear which clade represents the species in a strict sense. Parvoplaca athallina has been considered an Antarctic species, but according to our analyses, the species is shown to be bipolar occurring also in northern Europe, Greenland, Alaska and in California.

More specimens of Hydnotrya have been collected from southwestern China in recent years. Morphological and molecular analyses showed that they belonged to three species of Hydnotrya, of which two are new to science, H. oblongispora and H. zayuensis. The third one was H. laojunshanensis, previously reported in 2013. The new species are described, and their relationship to other species of Hydnotrya is discussed. H. laojunshanensis is re-described in more detail. The main morphological characters of 17 species of Hydnotrya are compared and a key to them is provided as well. [ABSTRACT FROM AUTHOR]

The deviation of conventional fungal niches is an important factor in the implications of hidden fungal diversity and global fungal numbers. The Xylariomycetidae (Sordariomycetes, Ascomycota), which is also referred to as xylarialean taxa, has a wide range of species that demonstrate a high degree of variation in their stromatic characteristics, showing either conspicuous or inconspicuous forms. In this study, samples were collected while focusing on temporal and spatial parameters and substrate characteristics. Based on internal transcribed spacer (ITS), 28S large subunit rDNA (LSU), RNA polymerase II second largest subunit (RPB2), and β-tubulin (TUB2) multigene phylogeny and morphology, five new species are introduced as Muscodor brunneascosporus, M. lamphunensis (Xylariaceae), Nigropunctata hydei, N. saccata (Incertae sedis), and Xenoanthostomella parvispora (Gyrotrichaceae). Plant substrates in the early stages of decay and attached to the host were feasible sample niches, with an emphasis on the collection of inconspicuous, hidden xylarialean species. The appearance of inconspicuous saprobic xylarialean forms during the rainy season may be linked to the change in nutritional mode, from endophytic mode during the dry season to saprobic in the wet. Therefore, it would be fascinating to concentrate future research on how seasonal fluctuations affect nutritional mode shifts, especially in northern Thailand, which would provide the optimal spatial characteristics. In order to establish a comprehensive linkage between endophytic and saprobic modes, it is imperative to have a substantial representation of endophytic isolate sequences resembling inconspicuous xylariaceous fungi within publicly accessible databases.

Thelocarpon periphysatum sp. nov. is described from marl quarries in the Netherlands. The species is characterized by perithecioid ascomata that have a green-yellowish ring around the ostiole, abundant periphyses and periphysoids that are up to 120 μm long, the absence of paraphyses and the wide, oblong and often somewhat asymmetrical ascospores. The perithecia are immersed in black cyanobacterial crusts on calcareous rocks. A worldwide key is provided to the 30 species of Thelocarpon that are currently accepted. [ABSTRACT FROM AUTHOR]

The tropical montane cloud forest is the most diverse and threatened vegetation type in Mexico. In the last decade, the number of described Ascomycetes species has notably increased, reaching more than 1300 species. This study describes six new species based on their molecular and morphological characteristics. Our results suggest that Mexico has the highest number of described species in the Neotropics. However, many other Mexican lineages still need to be described. [ABSTRACT FROM AUTHOR]

The manna lichens, a group of vagrant species with subfruticose and subfoliose thalli in the genus Circinaria Link, have received attention for millennia. Here, a new manna lichen species, Circinaria nimisii sp. nov. (Megasporaceae), is described and illustrated. This vagrant lichen is found on Mount Olympus in Greece and is the fourth known manna lichen in Europe. The new taxon is characterized by its subfruticose, densely-branched thallus with a muddy, earthy colour, whitish pseudocyphellae on tips of branches, mature apothecia distinctly adnate to stipitate, and paraplectenchymatous cortex tissue. Molecular sequence data from the standard barcoding marker (nrITS) also corroborate the distinction of this species from closely related congeners. Finally, Agrestia zerovii , previously known only from its type locality in Ukraine, is proposed as a new synonym of Circinaria hispida. [ABSTRACT FROM AUTHOR]

Background: Macrofungi are classified in the phylum Ascomycota and Basidiomycota and they are very important from an ecological and economic point of view. Most studies of fungi in Colombia have been carried out mainly in the Andean Region, especially in the Departments of Antioquia, Valle del Cauca and Cundinamarca. However, other Departments in the Andean Region, like Tolima, located in the Cordillera Central, are well documented for plants (4,797 species) and animals (2,983 species), but very poorly documented in terms of knowledge of fungal diversity. New information: This study provides a compiled and annotated checklist of all known macrofungi in the Department of Tolima, based on published literature and on the identification of new specimens collected from five localities of the Department. All records were updated taxonomically and we include detailed information on the localities in which they are distributed in the Department. The list includes 164 taxa distributed in 15 orders (Agaricales, Polyporales, Russulales, Boletales, Hymenochaetales, Xylariales, Auriculariales, Thelephorales, Cantharellales, Hypocreales, Pezizales, Gloeophyllales, Phallales, Tremellales, Dacrymycetales) and eighteen records in a doubtful taxa section. We present 26 new reports, 19 for Tolima and nine for Colombia. We also provide genetic and phylogenetic evidence of the occurrence of Gloeoporus telephoroides and Podoscypha venustula in Colombia. This checklist provides the basis for future studies on species diversity and taxonomy in Tolima, by identifying the least studied taxa and ecosystems and conservation priorities.
