Pertusaria inopinata Erichsen (= Lepra excludens (Nyl.) Hafellner), P. jurana Erichsen (= Lepra albescens (Huds.) Hafellner) and P. jurana var. confluens Erichsen (= Ochrolechia turneri (Sm.) Hasselrot) are synonymized based on results from comparison of morphology and secondary compound chemistry of type material. Lectotypes are selected for Pertusaria inopinata and P. jurana.

Two new phenolic compounds, methyl 2-hydroxy-4-methoxy-6-(2-oxopentyl)-benzoate (1) and 4-methoxy-6-pentyl-1,2-dihydroxybenzene (2), together with two known phenolic derivatives, were isolated from the Antarctic lichen Pertusaria dactylina (Pertusariaceae). The structures of the new compounds were determined by 1D and 2D NMR and HR-MS experiments, as well as by comparison of their data with the published values.

—Great Smoky Mountains National Park is renowned as one of the most biologically diverse tracts of land in North America and is the most visited national park in the United States. The park comprises ∼830 square miles, epitomizes eastern temperate hardwood forests of North America, and serves as a refuge for nearly 20,000 documented species from microbes to plants and mammals. Lichens comprise one particularly diverse group of organisms in the park. In this study, we review data from our 11 years of lichenological research in Great Smoky Mountains National Park. Based on approximately 6,000 new field collections generated, the park checklist now includes 920 species, a 129% increase over estimates made two decades ago. Nearly a quarter of the lichens reported in the park are known from only a single occurence whereas only 7% of the lichens are known from 20 or more occurences. An assessment of commonness/rarity for all 920 species indicates that nearly half of the park's lichens should be considered to be infrequent, rare, or exceptionally rare. We assessed the distributions of all 920 species and found that 54 are endemic to the southeastern United States, 30 are endemic to the southern Appalachians, and eight occur nowhere else than within the confines of the national park. We discuss biogeographical affinities of the park's lichen biota as a whole, delimiting six regional “floristic” connections. Our 11 years of research have resulted in the discovery of several species presumed to be extinct or near-extinct. We make one new combination (Fuscopannaria frullaniae) and describe five species as new to science, each commemorating National Park Service staff instrumental to the completion of the study: Heterodermia langdoniana, Lecanora darlingiae, Lecanora sachsiana, Leprocaulon nicholsiae, and Pertusaria superiana.

Endolichenic fungi, nonobligate microfungi that live in lichen, are promising as new bioresources of pharmacological compounds. We found that norlichexanthone isolated from the endolichenic fungus in Pertusaria laeviganda exhibited high antioxidant activity. Norlichexanthone produced by endolichenic fungus had the antioxidant activity with same level of ascorbic acid. This is the first report of high antioxidant activity of norlichexanthone.

Eleven new species of crustose, lichenized fungi are described from the Falkland Islands (Islas Malvinas). Nine species are saxicolous, whereasLecania vermisporaoccurs on the stems ofHebe ellipticaandTephromela lignicolais lignicolous on fence posts. The new species are:Bacidia marina, with a sordid blue-green K−, N+ violet epihymenium and acicular, multiseptate ascospores;B. pruinata, with pruinose apothecia and multiseptate ascospores;Buellia gypsyensis, with a thallus containing 5-O-methylhiascic acid and withAmandinea-type conidia;Cliostomum albidum, with pruinose apothecia lacking pigments;C. longisporum, with long narrow ascospores (c.20 × 3 µm);Coccotrema rubromarginatum, with a placodioid thallus having a red-brown margin and lower surface;Hymenelia microcarpa, with minute, immersed apothecia (Lecania vermispora, with vermiform, 3–6 septate ascospores;Lepra argentea, with papillate isidia with dark caps;Rhizocarpon malvinae, which is similar toR. reductumbut with a grey thallus, generally sessile apothecia with a thick raised margin and often with the Cinereorufa-green pigment in the epithecium and upper exciple; andTephromela lignicola,a sterile, sorediate species on fence posts. Most of these species are reported only from the Falkland Islands althoughCoccotrema rubromarginatumis also reported from Isla de los Estados and Isla Grande de Tierra del Fuego, Argentina. Ascoconidia are reported fromLepra argenteaand cephalodia fromPertusaria pachythallina.Keys to the species reported from the Falkland Islands in the genera of the newly described species are also provided.

Lichen is a symbiotic organism consisting of a photobiont (green algae or cyanobacterium) and a mycobiont (fungal). A taxonomic study of the crustose lichens in the forest of TAHURA R. Soeryohad been conducted based on morphological, anatomical, and chemical characters. In this research, we used the method of descriptive exploration to identify the crustose lichens and to study the distribution of the species in the forest of TAHURA R. Soeryo. Twenty species of crustose lichens with one unidentified species and one specimen identified to the group of family are reported. They are Graphina, Graphis, Phaeographis, Pertusaria, Pachyphiale, Phlyctis, Lepraria, Lecanora, Lecania, Cyphellium, and Megalospora. This research also found the new record species of Megalospora kalbii in Java. Crustose lichens are found in the areas with high light intensity of ≥ 1000 lux, average humidity of ≤ 90%, average temperature of18-190C, and at altitudes of ±1640 dpl. Graphina ruiziana could only be found at the altitude of ± 1780 dpl. The identification key to its species and distributions of other species are presented also in the article.

The study of biodiversity of lichens in Hokkaido, Japan, revealed seven species of genus Pertusaria s. l., sixof which are new to the island or whole Japan. The full list of species of Pertusaria s. str. and Lepra known from Hokkaidocomprises 18 species.

Turkonalassus mavi M. Nabozhenko & B. Keskin, sp. n. and Odocnemis rufocruralis M. Nabozhenko & B. Keskin, sp. n., two distinctive darkling beetle species of the tribe Helopini, are described from the Southeastern Anatolia region of Turkey, based on both their external morphology and genital structures. Turkonalassus mavi sp. n. differs from all congeners by the bluish dorsal surface of the body, the pronotum widest before middle, and wide merged baculi of the median lobe of the aedeagus. Odocnemis rufocruralis sp. n. belongs to the praelonga species-group. Odocnemis rufocruralis sp. n. is similar to O. torosica Nabozhenko & Keskin, 2016, O. terminassianae (Nabozhenko, 2011) and O. kakunini Nabozhenko & Keskin, 2016 but differs from all three taxa by the reddish-brown body with red legs, male apical maxillary palpomere wider than in female, elevate and narrowly separate male protrochanters, and the structure of the very long and narrow apical piece of the aedeagus. New data on distribution, bionomics, and trophic relations of several species of Helopini from Turkey are given. Host lichens are determined for nine species. The majority of studied adult beetles feed on lichens from the families Physciaceae and Parmeliaceae. Some examined taxa feed on Cladoniaceae. Feeding on crustose lichens is registered for the first time for Coleoptera, specifically Odocnemis rufocruralis sp. n. was observed to feed on Pertusaria sp.

Malicek, J., Palice, Z., Acton, A., Berger, F., Bouda, F., Sanderson, N. & Vondrak, J. 2018. Uholka primeval forest in the Ukrainian Carpathians — a keynote area for diversity of forest lichens in Europe. — Herzogia 31: 140–171.One of the largest European primeval forests, Uholka-Shyrokyi Luh in the Ukrainian Carpathians, has received increased attention in recent years. In spring 2015 we explored the lichen biota in the southern part of the reserve. Species richness of epiphytic and epixylic lichens presented in this paper far exceeds all numbers achieved in other Central European old-growth forests. In total, 370 lichenized and lichen-allied fungi and 30 lichenicolous fungi were recorded. We focused on forest lichens on organic substrata, inorganic substrata were largely ignored. Species composition in the Uholka forest includes many rare taxa and typical old-growth forest species: e.g. Cetrelia spp., Gyalecta spp., Leptogium saturninum, Lobaria pulmonaria, Ricasolia amplissima, Sclerophora farinacea, S. pallida, Thelopsis flaveola and T. rubella. Opegrapha fumosa, Pyrenula chlorospila and P. dermatodes represent oceanic species that are very rare outside western Europe. Biatora longispora, Calicium montanum, Menegazzia subsimilis, Micarea perparvula, Ochrolechia trochophora, Pyxine sorediata, Ramonia luteola and Thelotrema suecicum are examples of phytogeographically remarkable or generally very rare lichens. Thirty lichenized and ten lichenicolous fungi are new to Ukraine, including Biatora bacidioides and Pertusaria macounii not previously reported from Europe.

Kirschbaum, U. & Sipman, H. J. M. 2018. Lichen records from Northern Cyprus. – Herzogia 31: 245–251.Eighty-two taxa of lichenized fungi (lichenes) are reported from Northern Cyprus (Turkish Republic of Northern Cyprus), mostly from the Besparmak Mountains. Of these, thirty-four taxa are new for the northern part of the island, and 14 are new for the whole island. The large number of widespread species among the new records suggests that many more widespread species may show up. An unusual substrate, calcareous rock, is reported for Buellia tesserata, Rhizocarpon macrosporum and Xanthoparmelia attica. Pertusaria rhodiensis was found for the first time outside the Aegean Sea region.

Nine species of lichens from Bahia are described as new: Arthonia saxistellata, Cladonia inflata, Cladonia lichexanthonica, Cladonia minisaxicola, Coniocarpon piccolioides, Pertusaria lichexanthofarinosa, Pertusaria lichexanthoimmersa, Pertusaria lichexanthoverrucosa and Physcia sorediiconvexa. Many of the new species contain lichexanthone in the cortex and the substance is reported for the first time from Cladonia.

The crustose lichen genus Pertusaria comprises over ca. 800 species worldwide. In total, 20 Pertusaria species were localized to the Mt. Sorak and Jeju-do in Korea. To date, information regarding the distribution of Pertusaria species in the South Korean peninsula is scarce. In this study, we collected Pertusaria species across South Korea and identified them based on morphological, chemical, and molecular characteristics. Of the 387 samples collected, we identified 24 taxa and 1 variety, of which 17 were previously recorded, and 6 taxa were newly found in South Korea (P. leioplaca, P. leucosora var. violascens, P. texana, P. thiospoda, P. thwaitesii, and P. xanthodes), 2 known species were transferred to Varicellaria (Varicellaria lactea and V. velata), one species was transferred to Variolaria as a new record (Variolaria multipunctoides) and one was a new species (P. jogyeensis J. S. Park & J.-S. Hur, sp. nov.). Characteristics of the newly discovered species, P. jogyeensis, are as follows: smooth to bumpy thallus, scattered to crowded poriform apothecia, blackish ostioles, definitely sunken, thin yellowish green rims around ostioles, 8-spored ascus, and the presence of perlatolic acid and thiophaninic acid (chlorinated xanthone). Phylogenetic studies on P. jogyeensis based on the mitochondrial small subunit sequence revealed proximity to P. flavicans and P. texana, and supported its classification as a new species within the genus Pertusaria. Additionally, we describe the chemical composition and morphology of all listed species in detail and provide an artificial key for identification.

Seven new species, Pertusaria albula, P. dharugensis, P. ochrodigitula, P. pinnaculata, P. placocarpa, P. puttyensis and P. scabrida from New South Wales are reported as new to science.

A new revised checklist of lichenized fungi in Thailand is presented, including 1,292 species. Recent work on the taxonomy of these organisms in Thailand resulted in an enormous increase in our knowledge of the lichen biota of the country – the current checklist includes more than twice as many species as the previous catalogue published 15 years ago – and phylogenetic studies resulted in numerous changes in the generic classification of lichenized fungi. Hence, a new checklist is here presented summarizing the current knowledge of lichens in Thailand. Six new records are reported, viz. Acanthothecis salazinica, Bactrospora metabola, Buellia parastata, Diploschistes cinereocaesius, Rolfidium coccocarpioides, and Trapelia placodioides. Five previously recorded species, namely Lecanora carpinea, Platismatia glauca, P. lacunosa, P. tuckermanii and Roccella phycopsis are shown to be based on misidentifications and are excluded from the checklist. Three new combinations of species previously placed in Pertusaria to Lepra are proposed: L. bulolensis (A.W.Archer, Elix & Streimann) Schmitt & Lumbsch, L. patellifera (A.W.Archer) Schmitt & Lumbsch, and L. subventosa (Malme) Schmitt & Lumbsch.

This paper contributes to studies on the lichen biota of Arctic regions. The research was carried out in the forelands of eight glaciers and in the mature tundra surrounding them. Study areas were located in two parts of Svalbard: in the Kongsfjord (forelands of Austre Brøggerbreen, Vestre Brøggerbreen, Austre Lovénbreen, Midtre Lovénbreen, and Vestre Lovénbreen) and in the Isfjord (forelands of Rieperbreen, Svenbreen, and Ferdinandbreen). In each foreland and in the mature tundra surrounding it, a series of 1-m2 plots was established, within which a percentage cover for each species was determined. In total, 133 lichens and one lichenicolous fungus were recorded. Nineteen species were recorded for the first time in Svalbard: Agonimia allobata, Atla wheldonii, Bacidia herbarum, Catolechia wahlenbergii, Epigloea soleiformis, Lecanora behringii, Lepraria subalbicans, Leptogium arcticum, Pertusaria pseudocorallina, Placidiopsis custnani, Protothelenella corrosa, Pyrenidium actinellum, Spilonema revertens, Stereocaulon saxatile, Thelocarpon sphaerosporum, Toninia coelestina, Verrucaria elaeina, Verrucaria murina, and Verrucaria xyloxena. The lichen richness was the lowest in the Ferdinandbreen foreland (24 species) and the highest in the Rieperbreen foreland (82 species). Significant differences in species composition were found among the forelands studied, except for Austre and Vestre Brøggerbreen whose lichen composition was similar. The differences in lichen composition between mature tundra in the vicinity of the following forelands were identified: Vestre Brøggerbreen and Svenbreen, Austre Brøggerbreen and Svenbreen, and Austre Brøggerbreen and Ferdinandbreen. The most dominant group of lichens in both forelands and mature tundra were chlorolichens, not cyanolichens.

Five new species, Pertusaria dayi, P. glabra, P. heinari, P. montoensis, P. stenospora and a new combination, Pertusaria aphelospora, are reported from Australia. In addition, Pertusaria phulhuangensis described from Thailand, P. karkarensis, described from Papua New Guinea, and P. virensica, described from Florida, are reported from Australia for the first time.

An inventory of epiphyte lichens was carried out on 15 phorophytes of Quercus laurina Humb. & Bonpl. located along a mountain ridge in a mountain cloud forest at La Cortadura Ecological Reserve, Coatepec, Veracruz. For each tree the five zones following Johansson's method were distinguished. Ascents were made in selected trees using the single-rope technique, collecting samples along the trunk and some branches of the crown. A total of 126 lichen species were found, belonging to 60 genera, 24 families and 10 orders. The most diverse genus was Graphis (12 species), followed by Parmotrema (9), Hypotrachyna (8), Pertusaria and Usnea (5). Crustose lichens dominated (79%) over foliose (38%) and fruticose (8%) types. Although some species preferred one of the trees while others were common to all (13), no significant differences were observed between phorophytes. The genus Sticta was found in basal and intermediate tree zones; Ramalina and Usnea were recorded in all areas. Twenty-one new records are re...

A new chlorinated phenolic compound, methyl-3-chloro-2-hydroxy-4-methoxy-6-pentylbenzoate (1) and 4 known compounds (2-5) were isolated from the Antarctic lichen, Pertusaria dactylina ( Pertusariaceae). The structure of the new compound was determined by means of One-dimensional and two dimensional nuclear magnetic resonance (1D and 2D NMR) and high-resolution fast atom bombardment mass spectrometry (HRFABMS) experiments. The antimicrobial activities of compounds 1 to 5 against Staphylococcus aureus and Candida albicans were evaluated. The results showed that compound 1 exhibited a weak inhibitory effect against C. albicans with an IC50 value of 67 ± 7 μg/mL.

Pyrcha, M. & Oset, M. 2019. Saxicolous species of the genus Pertusaria s.l. in Poland. – Herzogia 32: 385 –397.Notes on the morphology, secondary chemistry, habitat requirements and distribution of saxicolous species belonging to the genus Pertusaria s.l. in Poland are provided. The following species are treated: Lepra aspergilla, L. corallina, L. ocellata, L. schaereri, Pertusaria flavicans, P. melanochlora, P. pseudocorallina and Varicellaria lactea. Although most of these species are reported from the southern part of the country, a key to all species known from Poland is provided. A chemotype of P. melanochlora lacking picrolichenic acid is reported for the first time. Pertusaria chiodectonoides and P. inopinata are considered uncertain records from Poland due to the lack of available material. The identity of P. eitneriana described from Poland is unclear; it was recorded only by the type collection.

We present floristic data from 82 localities mainly from eight mountain ranges of the Romanian Carpathians (Fagaras, Parâng, Cindrel, Harghita, Hasmas, Bihor, Maramures and Rodna). The main habitats investigated were subalpine and alpine communities, beech and spruce forests, and limestone areas at lower altitudes. During four field expeditions, 364 lichenized and three lichenicolous fungi were recorded. Thirty-seven taxa are new for Romania. Biatora subduplex, Helocarpon pulverulum, Lecanora filamentosa, L. flavoleprosa, Lecidea huxariensis, Leucocarpia biatorella, Myriospora dilatata, Pertusaria borealis, Placynthium dolichoterum, Reichlingia leopoldii, Rhizocarpon carpaticum and Vezdaea stipitata are new for southeastern Europe. Lecanora flowersiana is reported for the first time from Europe. Candelariella commutata, Cetrelia chicitae, Lecanora ...

This revision of Pertusaria in the Galapagos Islands documents twenty-four species, twenty-two being new to the archipelago. Secondary chemistry correlates well with morphology and anatomy and is particularly useful in distinguishing these taxa. Eight species are described as new to science, and seven are known only from the Galapagos: Pertusaria albineoides, P. cerroazulensis, P. darwiniana, P. medullamarilla, P. stictica, P. thioisidiata and P. xanthoisidiata. Pertusaria lueckingii is new, but it also occurs in Central America (El Salvador). Three new endemic varieties are described based on their chemistry: Pertusaria thioisidiata var. isidiogyrophorica, P. tejocotensis var. stictica and P. xantholeucoides var. thamnolica. In contrast with previous studies on other genera where rates of endemism of 8–10% were observed, in Pertusaria 30–37% of all species and 41–46% of all taxa are considered endemic.

Standardized lichen surveys were conducted on 849 trees in 132 ecological long-term observation plots in the Swiss Plateau and Pre-Alps: 262 lichen taxa were identified, 64 (24%) of them sorediate crustose species. Their mean percentage of the flora on individual trees and in individual plots was even higher. The mean percentage of crustose lichen species with vegetative propagules, such as soredia, was per plot significantly higher in the Pre-Alps than in the Plateau, higher in forest than in non-forest areas, and, according to the vegetation belts, lowest in the colline-submontane zone. It was found that the biodiversity of lichens could not be determined without considering the sorediate crustose lichens. Furthermore, by performing standardized surveys of all taxa, the occurrence of the following species in Switzerland was confirmed for the first time: Cliostomum leprosum, Fuscidea arboricola, Fuscidea pusilla, Hypocenomyce leucococca, Hypocenomyce sorophora, Lecanora norvegica, Lepraria eburnea, Lepraria elobata, Lepraria jackii, Lepraria obtusatica, Lepraria rigidula, Pertusaria boreahs and Rinodina griseosoralifera. Seven taxa that displayed distinctive chemistry, could not yet be identified.

Pertusarialean lichens include more than 300 species belonging to several independent phylogenetic lineages. Only some of these phylogenetic clades have been comprehensively sampled for molecular data, and formally described as genera. Here we present a taxonomic treatment of a group of pertusarialean lichens formerly known as "Pertusaria amara-group", "Monomurata-group", or "Variolaria-group", which includes widespread and well-known taxa such as P. amara, P. albescens, or P. ophthalmiza. We generated a 6-locus data set with 79 OTUs representing 75 species. The distinction of the Variolaria clade is supported and consequently, the resurrection of the genus Lepra is followed. Thirty-five new combinations into Lepra are proposed and the new species Lepra austropacifica is described from mangroves in the South Pacific. Lepra is circumscribed to include species with disciform ascomata, a weakly to non-amyloid hymenial gel, strongly amyloid asci without clear apical amyloid structures, containing 1 or 2, single-layered, thin-walled ascospores. Chlorinated xanthones are not present, but thamnolic and picrolichenic acids occur frequently, as well as orcinol depsides. Seventy-one species are accepted in the genus. Although the distinction of the genus from Pertusaria is strongly supported, the relationships of Lepra remain unresolved and the genus is tentatively placed in Pertusariales incertae sedis.

Sagediopsis bayozturkii, a lichenicolous fungus growing on Antarctic endemic speciesAcarospora macrocyclos, is described as new to science from three collections made at 65° south in the Argentine Islands (Graham Land, maritime Antarctica). The fungus has a distinct internal apical beak in the ascus and ellipsoid three-septate ascospores; therefore, it is the member ofSagediopsissubgenusHawksworthiella. Morphologically and anatomicallyS. bayozturkiiis most similar toS. campsterianaandS. pertusariicola, which are confined to the lichen hostsOchrolechiaspp. andPertusariaspp., respectively. In addition to having different hosts,S. bayozturkiidiffers from these two species by having smaller ascomata and shorter ascospores. Its similarities to other species of the genus are discussed, and an artificial key based on the published descriptions of the ten species now known in the genusSagediopsisis presented.

As a result of a field trip organised by the Spanish Lichen Society in Serranía de Ronda, south Spain, a catalogue of 360 taxa is presented (336 lichens, 24 lichenicolous fungi). The list includes three new records for the Iberian Peninsula: Arthonia paretinaria, Micarea myriocarpa and Niesslia keissleri, 51new ones for the Autonomous Andalusian Community, and three and 81 new ones for the province of Cádiz and of Málaga, respectively. After these results, the total updated number of the province of Málaga rises to 556 lichens and lichenicolous fungi. The best represented lichen genus is Cladonia (18) with the most species, unlike Lecanora (15), Pertusaria (12), Physconia (12) and Collema (9). As regard habitat, most lichen species are mainly corticolous (55%), as opposed to saxicolous (24%), terricolous (14%) as the species growing on other lichens as lichenicolous fungi (7%). The percentages of lichen growth forms are mainly foliose (50%) and crustose (31%), while fruticose (7%), crustose squamulose (6%) and dimorphic (6%) are less represented. The lichen wit Como resultado de la exploración llevada a cabo por la Sociedad Española de Liquenología en la Serranía de Ronda, sur de España, se presenta un catálogo de 360 taxones (336 líquenes y 24 hongos liquenícolas). La lista incluye tres nuevas citas para la Península Ibérica: Arthonia paretinaria, Micarea myriocarpa y Niesslia keissleri, 51 nuevas para la Comunidad Autónoma de Andalucía, 3 nuevas para la provincia de Cádiz y 81 para la de Málaga. Con estos resultados el número total de líquenes y hongos liquenícolas para la provincia de Málaga asciende a 556. Los géneros con mayor número de especies son Cladonia (18) con el número de especies más alto, Lecanora (15), Pertusaria (12), Physconia (12) y Collema (9). En relación al hábitat las especies corticícolas son las más abundantes (55%) seguido por saxícolas (24%), terrícolas (14%) y las que viven sobre los líquenes como hongos liquenícolas (7%). Respecto a los porcentajes de formas de crecimiento, la mayoría de los líquenes tienen biotipo foliáceo (50%) y crustáceo (31%), mientras que los talos fruticulosos (7%), escuamulosos (6%) y dimórficos (6 %) están menos representados. Predominan los líquenes con Chlorophyta como fotobionte (84%) mientras que las cianobacterias (15%) están muy poco representadas.

Seven new species, Pertusaria neotropica (with lichexanthone, hypothamnolic and salazinic acids), P. parasommerfeltii (with 4,5-dichlorolichexanthone and 2'-O-methylperlatolic acid), P. qinbaensis (norstictic acid and stictic acids), P. qiujiabaensis (with norstictic acid and 4,5-dichlorolichexanthone), P. sejilaensis (with protocetraric acid), P. subviolacea (with hypothamnolic and cryptothamnolic acids) and P. taibaiensis (with norstictic acid), are reported from China.

The new obligately lichenicolous fungus, Melaspilea tucumana Flakus, Etayo & Kukwa, inhabiting thalli of saxicolous Pertusaria s. lat. is described from Tucumano-Boliviano vegetation in Bolivia. The species is characterized by the gall formation and superficial, lirelliform to branched, aggregated apothecioid ascomata with widely exposed discs. The ascomata of M. tucumana are initially perithecioid and immersed in the host thallus, but become superficial and apothecioid when mature, and thus resemble the genus Buelliella. This may suggest the placement of the new species in Dothideomycetes.

The Hungarian lichenologist Odon Szatala described 169 species and infraspecific taxa, with a majority of these being based on his own collections. He also described taxa from material sent to him for identification. In this study, original material for 27 names (Aspicilia latiloba, A. microspora var. astroidea, A. microspora var. insensibilis, A. subpercaena, Bacidia rhodi, Buellia samothrakiana, Catillaria lenticularis var. transsilvatica, C. servitii, C. zsakii, Dermatocarpon fuscatum, Diplotomma alboatrum var. virescens, Lecania nylanderiana var. ochracea, Lecanora atra var. aegaeica, L. cengiae-samboae, L. rhodi, Lecidea aegaeica, L. aegaeica f. acrustacea, L. aegaeica f. albida, L. aegaeica var. verruculosa, L. euphorea f. decussata, L. iranica, L. stigmatea f. armeniaca, Pertusaria baskalensis, Physcia grisea var. elbursiana, Placodiella olivacea var. stampaliana, Porina rechingeri and Verrucaria filarszkyana) of taxa described by Szatala and based on material collected by others from Greece, Hungary, Iran, Iraq, Jordan, Palestine, Romania, Turkey and Ukraine was examined, and lectotypes were chosen.

Twenty lichen taxa are reported as new from Guinea-Bissau; one is new to continental Africa, seven are reported for the first time from western Africa and one is described here as new to science, namely Pertusaria guineabissauensis, which has eight hyaline, smooth-walled ascospore per ascus and contains stictic acid.

The consumption of lichens by Constrictotermes cyphergaster termites is suggested in the literature, but not yet with concrete evidence. We examined the use and richness of lichens consumed by C. cyphergaster during both the dry and rainy seasons in a semiarid environment in northeastern Brazil by monitoring the foraging of five termite colonies for ten consecutive days during each period. Twenty-nine species of corticolous lichens were consumed by C. cyphergaster, with seasonal variations in the richness of their ingestion. Chrysothrix xanthine, Pertusaria flavens, and Dirinaria confluens were the lichen species most consumed. TLC analyzes of termite gut contents revealed twelve secondary lichen compounds ingested in both seasons, while staining showed fragments of fungal hyphae, green algae, and typical lichen spores. This study represents the first systematic survey of the abundances of lichens that compose the diet of C. cyphergaster and indicates the seasonal selectivity of that resource related to the chemical compositions of the lichen stalks.

Fuscidea multispora Flakus, Kukwa & Rodr. Flakus and Malmidea attenboroughii Kukwa, Guzow-Krzeminska, Kosecka, Jablonska & Flakus are described as new to science based on morphological, chemical and molecular characters. Lepra subventosa var. hypothamnolica is genetically and chemically distinct from L. subventosa var. subventosa and a new name, Lepra pseudosubventosa Kukwa & Guzow-Krzeminska, is proposed due to the existence of Lepra hypothamnolica (Dibben) Lendemer & R.C. Harris . Pertusaria muricata , recently transferred to Lepra , is kept in the genus Pertusaria due to the highest similarity of ITS sequence with members of Pertusaria . The occurrence of Micarea hedlundii in the Southern Hemisphere is confirmed based on molecular evidence from Bolivian population. Lepra pseudosubventosa and Pertusaria muricata are reported as new to South America, and 20 taxa as new to Bolivia. Lepraria stephaniana , previously known only from the type locality, is reported from two more sites. An ascosporic state is reported for the first time for Lepra amaroides , as are new chemotypes. Molecular markers were used to place some sterile, sorediate crustose lichens in the family Graphidaceae. The phylogenetic positions of some sterile Malmidea specimens within Malmidaceae are also discussed.

Details of 11 lichen and 1 lichenicolous fungus taxa occurring in Belarus are presented, of which 6 lichens (Cliostomum leprosum, Fellhanera gyrophorica, Lecanora thysanophora, Lepraria eburnea, L.jackii, L.neglecta) and 1 lichenicolous fungus (Tremella hypogymniae) are newly reported for the country; new localities of recently reported Lepraria elobata and L. incana s.str. are presented and the occurrence of Chrysothrix candelaris, Loxospora elatina and Pertusaria coronata is confirmed. The taxonomy of Chrysothrix candelaris is briefly discussed and localities of Cliostomum leprosum from Poland are reported.

Four new species, Pertusaria ambigua, P. humilis, P. queenslandica and P. submalvinae, are reported from Australia and two new species, Pertusaria allosorodes and P. wirthii, are reported from New Zealand.
