Acta Musei Moraviae, Scientiae biologicae (Brno) 102(1): 49–87. – An annotated list of some remarkable collections of rare polypores, mainly from the territory of Moravia, is given. Altogether, 36 species are presented, most of them illlustrated with a colour photograph. Some information on their distribution, ecology and key characters is provided. New localities of species previously known merely from only one (Aurantiporus alborubescens, Chaetoporellus latitans, Riopa metamorphosa) or two (Jahnoporus hirtus) in Czechia were disclosed, and a few species (Byssoporia terrestris, Phellinus lundellii) are published for the first time for the territory of Moravia. Further, many new localities for certain other very rare polypores (Gelatoporia subvermispora, Porotheleum fimbriatum, Tyromyces kmetii, Yuchengia narymica) are presented. Key words. Moravia, rare polypores, new records Introduction Polyporoid fungi (or Polyporales s.l.) are among the best-explored groups of macromycetes in Czechia, thanks to the many prominent mycologists who have addressed this group in the past (A.
