Notes – Mycothermus was published by Natvig et al. (2015) but as an invalid genus. The genus was validated by Wang et al. (2019b) based on multi-gene phylogenetic analyses with rpb2, tub2, ITS and LSU. The genus is characterised by its thermophilic habit, hyaline to subhyaline hyphae, holothallic chlamydospores that are thick-walled, brown, smooth to verrucose and doliiform, globose, subglobose, oblong or obovoid. The sexual morphs are undetermined.

Type species: Mycothermus thermophilus (Cooney & R. Emers.) X. Wei Wang, Houbraken & D.O. Natvig, in Wang, Yang, Meijer, Kraak, Sun, Jiang, Wu, Bai, Seifert, Crous, Samson & Houbraken, Stud. Mycol. 93: 107 (2018).
