Notes – Pseudosporidesmiaceae, introduced by Crous et al. (2017a), included two species of Pseudosporidesmium and a taxon tentatively identified as Repetophragma inflatum (GenBank number DQ408576), of which the characters could not be confirmed. Pseudosporidesmiaceae is assigned to Xylariales (Xylariomycetidae, Sordariomycetes) based on phylogenetic analysis (Su et al. 2016b, Crous et al. 2017a).
