The genus Myceliophthora

The hyphomycetous genus Myceliophthora Cost. is reintroduced with its type species, M. lutea Cost., and two new combinations are proposed: Myceliophthora thermophila and M. fergusii. The genus is characterised by blastoconidia with narrow basal attachments (sometimes borne on ampulliform swellings) and by lacking arthroconidia. All three species are more or less thermophilic, with temperature optima between 30 and 45°C.
