Based on detailed investigations and long-term field observations, the authors describe two critical species of the genus Inocybe from the section Fibrillosae: Inocybe posterula and Inocybe lucifuga. Additionally, a new species, Inocybe pseudodestricta sp. nov., is described and its taxonomic validity is justified. Synonymy and nomenclatural issues are discussed.
