Classification: Hermatomycetaceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi

The genus was erected by Spegazzini (1911) to accommodate H. tucumanensis as the type species. The asexual morph is characterized by sporodochial conidiomata and brown, muriform lenticular conidia or hyaline and cylindrical conidia (Hashimoto et al. 2017, Hyde et al 2019). Most of the species are saprobic on various plants of angiosperms and monocots, with a few rarely found on ferns (Castañeda-Ruiz & Heredia 2000) or gymnosperms (Mel’nik 2000, Hashimoto et al. 2017). These species have a worldwide distribution (Hashimoto et al. 2017). 

Type species: Hermatomyces tucumanensis Speg., Anal. Mus. nac. B. Aires, Ser. 3 13: 446 (1910) [1911].

Other accepted species: Species Fungorum – search Hermatomyces.
