Mycosphere notes 275-324: A morpho-taxonomic revision and typification of obscure Dothideomycetes genera (incertae sedis)

This is the 6th in a series, Mycosphere notes, wherein 50 taxonomic notes are provided based on types of genera and specimens in the class Dothideomycetes. These genera have so far not been formally accommodated at any lower taxonomic rank and therefore referred to the Dothideomycetes genera incertae sedis. Notes on the economic significance, wherever known, of each genus are also provided, wherever known. Three new families, viz. Dubujianaceae, Endosporiaceae and Macrovalsariaceae, are introduced in this paper. Thirteen genera namely Acarella Syd., Asteronia (Sacc.) P. Henn., Belizeana Kohlm. & Volkm., Bonaria Bat., Byssocallis Syd., Byssolophis Clem., Dothichiza Lib. ex Roum., Dothidasteromella Hohn., Englerodothis Theiss. & Syd., Eumela Syd., Gibbago E.G. Simmon, Gibberidea Fuckel and Koordersiella Hohn are assigned to other families based on morphological investigation and phylogenetic analysis of sequence data available in GenBank. Acarella costaricensis Syd. and Perizomella inquinans Syd. are synonymized based on morphology and transferred to the family Vizellaceae. Chaetosticta perforata (Ellis & Everh.) Petr. & Syd. (equivalent to Chaetomella perforata Ellis & Everh.) and Pyrenochaeta erysiphoides Sacc. are synonymized, as all the three species share similar morphological characters and all were collected from the same host (Cirsium sp). The genus Kullhemia P. Karst. is synonymized under Strangospora Korb. based on morphology. The genus Didymocyrtidium Vain. is typified with Didymocyrtidium nudum Vain. (H6022676) as type species. Four genera namely Bahusutrabeeja Subram. & Bhat, Botryohypoxylon Samuels & J.D. Rogers, Dilophospora Desm. and Hassea Zahlbr. are excluded from the Dothideomycetes. All taxa are described and illustrated.
