Type species – Thermothelomyces thermophilus (Apinis) Y. Marín, Stchigel, Guarro & Cano

Notes – Thermothelomyces was introduced by Marin-Felix et al. (2015) and includes four species. Phylogenetic analyses of combined ITS, tef1 and rpb2 datasets showed that Thermothelomyces belongs to Chaetomiaceae (Marin-Felix et al. 2015). The genus is characterised by a thermophilic habit, ascomata that are immersed or semi-immersed, globose, cleistothecial, black, and glabrous, with a wall of textura epidermoidea. Asci are ellipsoidal, thin-walled, pedicellate, and evanescent, and ascospores are ellipsoidal, dark brown to black at maturity, thick- and smooth-walled, with a single germ pore. In the asexual morph, conidiophores are micronematous or semi-macronematous and conidia are holoblastic, brown, subglobose or obovoid to ellipsoidal, ornamented or rarely smooth.
