Notes – The monotypic genus Pseudosydowia was described by Thambugala et al. (2014a) in Saccotheciaceae. The type species of this genus (Pseudosydowia eucalypti) was originally described by Verwoerd & du Plessis (1931) as Sphaerulina eucalypti and later it was transferred to Sydowia based on its Sclerophoma and Hormonema asexual morphs and the thick-walled ascostromata (Crous et al. 2003b). However, more fresh collections and culture studies of Pseudosydowia need to be made in order to clarify the relationship with other genera in the family. The genus is characterized by amphigenous, subepidermal ascostromata, 2- to multi-seriate, hyaline ascospores, pycnidial to avervular, amphigenous conidiomata and aseptate, brown conidia.
