A survey is given of the infrageneric classification of the genus Entoloma sensu lato (Basidiomycetes, Agaricales), underlaying the author’s recent revisions of Entoloma in the Netherlands and adjacent regions (Noordeloos, 1979, 1980, 1981). The taxonomic value of the characters currently used in this genus is discussed. Three new subgenera are described, viz. Allocybe, Inocephalus, and Omphaliopsis, and subgenus Paraleptonia Romagn. is validated; several new combinations are made.
