Index Fungorum number: IF 10473; MycoBank number: MB 10473; Facesoffungi number: FoF 03761; 21 morphological species (Species Fungorum 2020), 8 species with sequence data.
Type species – Zygosporium oscheoides Mont.
Notes – Zygosporium was introduced by Montagne (1842) with Z. oscheoides as the type species. Species are usually saprobes in temperate to tropical regions (Photita et al. 2001, Whitton et al. 2003, Manoharachary et al. 2006, McKenzie et al. 2007, Abbas et al. 2011, Pratibha et al. 2012, Taheriyan et al. 2014). Taxa are hyphomycetous (asexual morphs) with darkly pigmented colonies, incurved vesicular cells, globose or ellipsoid and smooth-walled or variously ornamented conidia (Mason 1941, Hughes 1951c). Sequence data are available only for Z. chartarum, Z. echinosporum, Z. gibbum, Z. masonii, Z. minus, Z. mycophilum, Z. oscheoides and Z. pseudogibbum. In this entry, a new collection of Z. masonii from Dracaena is illustrated (Fig. 1).
