A phylogenetic and morphological study of the genus <i>Dermoloma</i> (<i>Agaricales</i>, <i>Tricholomataceae</i>) in Europe and North America exposes inefficiency of opportunistic species descriptions.

ABSTRACT: Dermoloma is traditionally known as a small genus of agarics classified in the family Tricholomataceae. This study implemented a multilocus phylogeny of six DNA regions to recognize phylogenetic species within the genus. The species concept is reinforced by observations of well-defined morphological characters enhanced by long term sampling effort in Europe and North America. Thirty European Dermoloma species are described, including 16 new species from Europe and three from North American. These species are classified into two subgenera morphologically distinguished by spores with positive or negative amyloid reaction. A new genus Neodermoloma is introduced for the Dermoloma-like species N.campestre. Localized or continental-scale species endemici
