Fungal diversity notes is one of the important journal series of fungal taxonomy that provide detailed descriptions and illustrations of new fungal taxa, as well as providing new information of fungal taxa worldwide. This article is the 11th contribution to the fungal diversity notes series, in which 126 taxa distributed in two phyla, six classes, 24 orders and 55 families are described and illustrated. Taxa in this study were mainly collected from Italy by Erio Camporesi and also collected from China, India and Thailand, as well as in some other European, North American and South American countries. Taxa described in the present study include two new families, 12 new genera, 82 new species, five new combinations and 25 new records on new hosts and new geographical distributions as well as sexual-asexual reports.

A new freshwater ascomycetous species, Wicklowia submersa was found on submerged wood in a freshwater stream in Krabi Province in southern Thailand. This is a second species in a monotypic family. Morphological examination and phylogenetic analysis of LSU and SSU sequence data support this new species as belonging to Wicklowia in the family Wicklowiaceae (Pleosporales). Wicklowia submersa possesses ascomata that are immersed, erumpent when mature, raised and visible as dark oval or slit-like structures on host surface. The bitunicate asci have well-developed ocular chambers when immature with a short pedicel. Ascospores are ellipsoidal-oblong, asymmetrical, 1-septate, guttulate when immature, hyaline, with a distinctly mucilaginous sheath. The characteristics of the asci, and ascospores which lack both apical and basal appendages distinguish it from the type species W. aquatic. A description, illustration and comparison of the new species is provided. The risk of introducing monotypic families is discussed.

This is a continuation of a series focused on providing a stable platform for the taxonomy of phytopathogenic fungi and fungus-like organisms. This paper focuses on one family:Erysiphaceaeand 24 phytopathogenic genera:Armillaria, Barriopsis,Cercospora,Cladosporium,Clinoconidium,Colletotrichum,Cylindrocladiella,Dothidotthia,,Fomitopsis,Ganoderma,Golovinomyces,Heterobasidium,Meliola,Mucor,Neoerysiphe,Nothophoma,Phellinus,Phytophthora,Pseudoseptoria,Pythium,Rhizopus,Stemphylium,ThyrostromaandWojnowiciella.Each genus is provided with a taxonomic background, distribution, hosts, disease symptoms, and updated backbone trees. Species confirmed with pathogenicity studies are denoted when data are available. Six of the genera are updated from previous entries as many new species have been described.

This is the twelfth contribution to the Fungal Diversity Notes series on fungal taxonomy, based on materials collected from many countries which were examined and described using the methods of morphology, anatomy, and strain culture, combined with DNA sequence analyses. 110 taxa are described and illustrated, including five new genera, 92 new species, eight new combinations and other taxonomic contributions (one new sequenced species, one new host and three new records) which are accommodated in 40 families and 1 incertae sedis in Dothideomycetes. The new genera are Amyloceraceomyces, Catenuliconidia, Hansenopezia, Ionopezia and Magnopulchromyces. The new species are Amyloceraceomyces angustisporus, Amylocorticium ellipsosporum, Arthrinium sorghi, Catenuliconidia uniseptata, Clavulina sphaeropedunculata, Colletotrichum parthenocissicola, Coniothyrium triseptatum, Cortinarius indorusseus, C. paurigarhwalensis, C. sinensis, C. subsanguineus, C. xiaojinensis, Diaporthe pimpinellae, Dictyosporella guizhouensis, Diplodia torilicola, Fuscoporia marquesiana, F. semiarida, Hansenopezia decora, Helicoarctatus thailandicus, Hirsutella hongheensis, Humidicutis brunneovinacea, Lentaria gossypina, L. variabilis, Lycoperdon lahorense, L. pseudocurtisii, Magnopulchromyces scorpiophorus, Moelleriella gracilispora, Neodevriesia manglicola, Neodidymelliopsis salvia, N. urticae, Neoroussoella magnoliae, Neottiella gigaspora, Ophiosphaerella chiangraiensis, Phaeotremella yunnanensis, Podosphaera yulii, Rigidoporus juniperinus, Rhodofomitopsis pseudofeei, Russula benghalensis, Scleroramularia vermispora, Scytinopogon minisporus, Sporormurispora paulsenii, Thaxteriellopsis obliqus, Tomentella asiae- orientalis, T. atrobadia, T. atrocastanea, T. aureomarginata, T. brevis, T. brunneoflava, T. brunneogrisea, T. capitatocystidiata, T. changbaiensis, T. citrinocystidiata, T. coffeae, T. conclusa, T. cystidiata, T. dimidiata, T. duplexa, T. efibulata, T. efibulis, T. farinosa, T. flavidobadia, T. fuscocrustosa, T. fuscofarinosa, T. fuscogranulosa, T. fuscopelliculosa, T. globospora, T. gloeocystidiata, T. griseocastanea, T. griseofusca, T. griseomarginata, T. inconspicua, T. incrustata, T. interrupta, T. liaoningensis, T. longiaculeifera, T. longiechinuli, T. megaspora, T. olivacea, T. olivaceobrunnea, T. pallidobrunnea, T. pallidomarginata, T. parvispora, T. pertenuis, T. qingyuanensis, T. segregata, T. separata, T. stipitata, T. storea, Trichoderma ceratophylletum, Tyromyces minutulus, Umbelopsis heterosporus and Xylolentia reniformis. The new combinations are Antrodiella descendena, Chloridium macrocladum, Hansenopezia retrocurvata, Rhodofomitopsis monomitica, Rh. oleracea, Fuscoporia licnoides, F. scruposa and Ionopezia gerardii. A new sequenced species (Graphis supracola), one new host (Aplosporella prunicola) and three new geographical records (Golovinomyces monardae, Paradictyoarthrinium diffractum and Prosthemium betulinum), are reported.

Verruconis heveae, a new species accommodated in Sympoventuriaceae was isolated from dried latex on bark of a rubber tree (Hevea brasiliensis) collected from Phayao Province, Thailand. The comparison of its morphological characters distinguished V. heveae from other Verruconis species by having brown, woolly mycelium on the natural substrate and solitary, ellipsoidal to subglobose, 1–3 septate conidia. Phylogenetic analysis of a combined LSU and ITS dataset revealed a distinct lineage within Sympoventuriaceae.

The species of the family Massariaceae have been reported as hemibiotrophs, saprotrophs or weak pathogens. Massarioramusculicols chiangraiensis gen. et sp. nov. (Massariaceae) is introduced in this study to accommodate a taxon isolated from dead twigs of an unknown host, collected in Thailand. Phylogenetic analysis of large subunit (LSU) rRNA sequence data and morphological studies show the relationships of M . chiangraiensis with other genera in Massariaceae. Three genera Massaria , Massarioramusculicola and Neomassaria are accepted in Massariaceae and a key to genera of the family is provided. The genus Massarioramusculicola is clearly different from Massaria , whereas the latter has larger ascomata typically firmly embedded in pseudostromatic tissues intermixed with substrate cells, often surrounded by blackened marginal zones and covered by a dark clypeus, as well as brown to dark brown, larger, 3-disto- or euseptate ascospores. Massarioramusculicola can be distinguished from Neomassaria in having a peridium with two strata comprising dark brown to hyaline cells of textura angularis , rarely branched, septate trabeculae and 3-septate ascoapores.
