Heteromyces
Heteromyces is a genus of lichenized fungi in the family Cladoniaceae. It is a monotypic genus, containing the single species Heteromyces rubescens. Both the genus and species were described by Swiss lichenologist Johannes Müller Argoviensis in 1889. The name "Heteromyces" was also used for a genus circumscribed by Lindsay S. Olive in 1957; this usage is illegitimate because of the prior usage of this name by Müller. Olive's concept of "Heteromyces" was renamed to "Oliveonia" by Marinus Anton Donk in 1958.
