Inocybe descissa (Fr.) Quél. in the sense of classical descriptions and illustrations in Battarra and Fries is treated in detail by the authors as a frequently misinterpreted species, but faithful to its habitat of subxerophilous oak forests and similar parklands with oaks and maples. The species is placed in Singer's system under the section Inocibium [Lacerae] (Fr.) Sacc., Fibrillosae Heim, as subsection Descissae subsect. nov.
