Notes.

Iturriaga and Korf (1990) proposed the dematiaceous hyphomycete genus Pseudospiropes ( Ellis 1971) , typified by P. nodosus , as a generic synonym of the apothecial ascomycete genus Strossmayeria ( Schulzer 1881) ( Helotiales ). The connection between the sexual and asexual morphs was initially established experimentally for two species of Strossmayeria sp. by Iturriaga and Korf (1984), and later demonstrated for P. josserandii , P. nodosus , P. simplex , several additional Pseudospiropes species, and taxa referred to as the “ P. nodosus type ” and the “ P. simplex complex ” ( Iturriaga and Korf 1990). The remaining species of Pseudospiropes still require critical revision. Based on Morris’s (1972) original description and illustration of P. costaricensis , we suggest that this species is more appropriately accommodated in Strossmayeria than Pleurophragmium , pending revision of the holotype and the availability of its molecular data.
