Epiphytes. Superficial hyphae with appressoria. Appressoria alternate, about 20% opposite, stalk cells cylindrical to cuneate, head cells ovate to globose, stellately sublobate. Sexual morph: Thyriothecia scattered, orbicular, stellately dehiscing at the centre, margin fimbriate, fringed hyphae straight to flexuous. Asci 8-spored, bitunicate, oblong to cylindrical, slightly pedicellate. Ascospores brown, uniseptate, apiosporous, larger cell, ovate to oblong, smaller cell, ovate to globose, often mammiform, smooth-walled. Asexual morph: Unknown (adapted from Hosagoudar and Harish 2010)
Type species: Vishnumyces otonephelii Hosag. & Harish
Notes: Vishnumyces is characterised by orbicular thyriothecia, which dehisce stellately at the centre, and uniseptate ascospores. Vishnumyces differs from other genera of Asterinacaeae in having apiospores with a small basal cell (Harish and Hosagoudar 2010). Hongsanan et al. (2014) treated Vishnumyces as a doubtful genus in Mycosphaerellaceae. Fresh collections are needed to confirm the taxonomic placement of Vishnumyces.
