Phaeocryptopus was introduced as a monotypic genus. Petrak (1962), Butin (1970) and Farr (1984) introduced several other species (Thambugala et al. 2014a). Müller & von Arx (1950) included Phaeocryptopus in Venturiaceae. Rhizosphaera species are accepted as asexual morphs of Phaeocryptopus. However, this relationship has not been clearly established (Winton et al. 2007, Thambugala et al. 2014a). Phylogenetic analysis of Winton et al. (2007) and Schoch et al. (2009a) showed that P. gaeumannii clustered in Mycosphaerellaceae, Capnodiales while P. nudus nested in Dothioraceae, Dothideales (Thambugala et al. 2014a). In our multi-gene phylogenetic analysis, P. nudus is separated with high bootstrap support with its internal node (94 % MLBS, 0.99 PP) within family Dothideaceae. Phaeocryptopus is separated from other genera in the family in having superficial, gregarious, globose to globose-depressed, black ascostromata (Thambugala et al. 2014a).

Type species: Phaeocryptopus nudus (Peck) Petr., Annls mycol. 36(1): 15 (1938)

Other accepted species: Species Fungorum – search Phaeocryptopus.
