Abstract
An extensive taxonomic study based on the type collection of Mycena phaeophylla revealed its conspecificity with M. clavata. Redescription of Kühner’s original collections of M. phaeophylla is provided as well as a detailed description of M. clavata based on European material. A lectotype for M. phaeophylla is designated. Additional study on collections of M. speirea confirmed that this closely related species can be separated easily from M. clavata. New key to subsection Omphaliariae of section Hiemales is proposed.
We thank David Hawksworth (University of Madrid, Spain) for the nomenclatural advice, Pierre-Arthur Moreau (University of Lille, France) for valuable discussions on the present study, Isobel Simonsen for linguistic corrections, Richard W. Kerrigan and two anonymous reviewers for the valuable comments on the manuscript. We also thank keepers of herbaria C, S, G, O for kind loan of the material. This work is partly a result of studies carried out under grant No. 6 P04G 083 20, financed by the Polish State Committee of Scientific Research (KBN).
