title: Calocybella, a new genus for Rugosomyces pudicus (Agaricales, Lyophyllaceae) and emendation of the genus Gerhardtia.
abstract: Calocybella is a new genus established to accommodate Rugosomyces pudicus. Phylogenetic analyses based on a LSU-ITS sequence dataset place Calocybella sister to Gerhardtia from which it differs morphologically in the presence of clamp-connections and reddening context. The genus Gerhardtia is emended to also include taxa with smooth spores. According to our morphological analysis of voucher material, Calocybe juncicola s. auct. is shown to be Calocybella pudica.
