Notulae ad Floram agaricinam neerlandicam — XIX. A revision of Dermoloma (J. Lange) Sing.—1

The taxonomic position of Dermoloma is discussed. It is concluded that it is an independent genus close to Camarophyllopsis belonging to the tribe Hygrocybeae of the Tricholomataceae. The variability in some microscopic characters is described and compared with data from other authors. A key and descriptions are given of the indigenous taxa with inamyloid spores. Dermoloma atrocinereum and D. fuscobrunneum are reduced to synonyms of D. cuneifolium. A new variety of the latter species, var. punctipes, is described.
