Type species: Marasasiomyces karoo (B. Sutton & Marasas) Crous, in Crous, Müller, Sánchez, Giordano, Bianchinotti, Anderson & Groenewald, Phytotaxa 202(2): 85 (2015).
≡ Tiarosporella graminis var. karoo B. Sutton & Marasas, Trans. Br. mycol. Soc. 67(1): 73 (1976)
Notes: This monotypic genus was introduced by Crous et al. (2015b) for M. karooo to accommodate tiarosporella-like taxa. Marasasiomyces is distinguished from Tiarosporella by conidiomata with long necks covered in brown setae, and holoblastic conidiogenesis. These characters are similar to Eutiarosporella, but differ on account of the non-clustered conidiomata.
