Hosagoudar et al. (2014) introduced Andamanomyces as a monotypic genus within Asterinales, Dothideomycetidae in Dothideomycetes with the type species Andamanomyces fragariae. Andamanomyces characterized by brown, septate, appressoriate, ectophytic, branched mycelium, solitary but mostly in couplets, unicellular appressoria, ellipsoidal with central vertical suture formed by dissolving or splitting, oval thyriothecia, 8–spored, bitunicate, globose asci, oblong, uniseptate, conglobate, constricted at the septum ascospores. Andamanomyces can be distinguished by having elliptical thyriothecia with central vertical sutures with Asterolibertia and Cirsosia (Arnaud 1918). Only one species has been accepted, and this genus is the remaining monotypic genus.

Type species: Andamanomyces fragariae Hosag.

Other accepted species: This genus is monotypic.
