This article is the 13th contribution in the Fungal Diversity Notes series, wherein 125 taxa from four phyla, ten classes, 31 orders, 69 families, 92 genera and three genera incertae sedis are treated, demonstrating worldwide and geographic distribution. Fungal taxa described and illustrated in the present study include three new genera, 69 new species, one new combination, one reference specimen and 51 new records on new hosts and new geographical distributions. Three new genera, Cylindrotorula ( Torulaceae ), Scolecoleotia ( Leotiales genus incertae sedis ) and Xenovaginatispora ( Lindomycetaceae ) are introduced based on distinct phylogenetic lineages and unique morphologies. Newly described species are Aspergillus lannaensis , Cercophora dulciaquae , Cladophialophora aquatica , Coprinellus punjabensis , Cortinarius alutarius , C. mammillatus , C. quercoflocculosus , Coryneum fagi , Cruentomycena uttarakhandina , Cryptocoryneum rosae , Cyathus uniperidiolus , Cylindrotorula indica , Diaporthe chamaeropicola , Didymella azollae , Diplodia alanphillipsii , Dothiora coronicola , Efibula rodriguezarmasiae , Erysiphe salicicola , Fusarium queenslandicum , Geastrum gorgonicum , G. hansagiense , Helicosporium sexualis , Helminthosporium chiangraiensis , Hongkongmyces kokensis , Hydrophilomyces hydraenae , Hygrocybe boertmannii , Hyphoderma australosetigerum , Hyphodontia yunnanensis , Khaleijomyces umikazeana , Laboulbenia divisa , Laboulbenia triarthronis , Laccaria populina , Lactarius pallidozonarius , Lepidosphaeria strobelii , Longipedicellata megafusiformis , Lophiotrema lincangensis , Marasmius benghalensis , M. jinfoshanensis , M. subtropicus , Mariannaea camelliae , Melanographium smilaxii , Microbotryum polycnemoides , Mimeomyces digitatus , Minutisphaera thailandensis , Mortierella solitaria , ...

During a study of diversity and taxonomy of lignicolous freshwater fungi in China, nine species of Acrogenospora were collected. Seven of these were new species and they are described and illustrated. With morphology, additional evidence to support establishment of new species is provided by phylogeny derived from DNA sequence analyses of a combined LSU, SSU, TEF1α, and RPB2 sequence dataset. Acrogenospora subprolata and A. verrucispora were re-collected and sequenced for the first time. The genus Acrogenospora is far more species rich than originally thought, with nine species found in a small area of Yunnan Province, China.
