A new species of the genus Micromphale S. F. Gray (Agaricales), M. carneo-pallidum Pouz., is described, which is closely related to M. inodorum (Pat.) Svrč. and grows exclusively on xerothermic grassy slopes. The distinctions between the genera Micromphale S. F. Gray and Collybia (Fr.) Kumm. are also discussed, and Marasmius rufocarneus Velen is identified with Micromphale foetidum (Sow. ex Fr.) Sing.
