Powellomyces, a new genus in the Spizellomycetales

Powellomyces (order Spizellomycetales) is erected for soil-inhabiting chytrids previously classified in Entophlyctis. Fischer's narrative and figures indicate that Entophlyctis was originally described to accommodate aquatic, chytridialean species, and consequently this is not an appropriate genus for spizellomycetalean species. Powellomyces hirtus sp.nov. and Powellomyces variabilis nom.nov. both develop exogenously but differ in distribution of rhizoids on germlings and in colour of colonies in culture. Key words: Chytridiales, Entophlyctis, Powellomyces, Spizellomycetales.
