Abstract

This paper provides illustrations, detailed morphological descriptions, and comments on duplicates of type specimens of myxomycetes from the personal collection of S.L. Stephenson donated to LE (Russia) in 1999. The isotype of Licea pseudoconica, the isoparatypes of Badhamia rugulosa, Diderma corrugatum, Licea alexopouli, L. perexigua, Physarum alpestre (≡Nannengaella alpestre), the isosyntype of Comatricha rispaudii (≡Paradiachea rispaudii), and the ‘isotopotypes’ of Licea pumila and Perichaena syncarpon were studied in detail. For the two isoparatypes of Trabrooksia applanata, which are part of this collection, only a brief description of the specimens (not sporocarps) is given, as this taxon will soon be discussed in detail in a separate paper.
