Musumecia , a new genus of Agaricales, is described to accommodate the new species Musumecia bettlachensis . Based on a combined ITS– and LSU–rDNA Bayesian, Maximum Likelihood and Maximum Parsimony analysis, Musumecia clearly clusters within the Tricholomatoid clade, where it is sister to Pseudoclitocybe . Musumecia is distinguished from allied genera by a unique combination of macro‐ and micromorphological characters, including basidiomes with a clitocyboid/hygrophoroid habit, emerging from a fleshy pseudosclerotial mass (pseudosclerotium), decurrent and thick lamellae, a brown darkening of both lamellae and stipe, whitish‐cream spore print, elongated non‐siderophilous basidia, smooth, acyanophilous and inamyloid basidiospores, and the absence of both cystidia and clamp‐connections.
