Acta Musei Moraviae, Scientiae biologicae (Brno) 95(1): 143–162. – The authors give descriptions of macro- and microfeatures of 13 rare or lesser-known macromycetes collected in Moravia (Czech Republic). Elaphomyces septatus and Lepiota griseovirens are recorded for the first time in the Czech Republic. Lepiota lilacea and Psilocybe laetissima are published for the first time from Moravia, Coprinopsis spelaiophylla for the second time. Armillaria ectypa has been re-collected after almost 50 years, Clavariadelphus truncatus after almost 30 years, and Geastrum berkeleyi after more than 20 years. Biscogniauxia simplicior and Lyophyllum leucophaeatum have only a few recent Moravian localities. Further, Callistosporium pinicola represents a rare, only recently-recorded taxon. Crepidotus crocophyllus has been collected outside its previously-known range in the southernmost part of Moravia. Aleurodiscus disciformis is a critically endangered species that has been collected at several localities in Moravia. Key words.
