Three new species of myxomycetes from Siberia.

Abstract

Information is provided on the find of three new species of myxomycetes of the Perichaena and Gulielmina genera. The description, ecology, known localities, and differences from morphologically similar species are given. A comparative study of the new myxomycete species with similar species was carried out using scanning electron microscopy. Micrographs with relevant details of sporocarps and spores are presented. An analysis of the molecular phylogeny of the new species was carried out and their connections with representatives of bright-spored myxomycetes are shown.
