Abstract

Abstract: A new widespread myxomycete species, Physarum pseudonotabile, inhabiting the arid regions of the Eurasia, South and North America is described and illustrated. Our goal was to explore boundaries among morphological forms of this species, with a particular focus on differences to similar species of Physarum. Tentatively assigned to Ph. notabile T. Macbr., the new species was found to be most frequent or at least very frequent in surveys based on the moist chamber culture technique with samples of ground litter, bark of living plants, and weathered dung of herbivorous animals collected in dry steppe and deserts of the Caspian lowland (Russia), Kazakhstan, Mongolia and China, as well as in the arid landscapes of Oman, Spain, Argentina and USA. Myxomycete specimens were examined with scanning electron microscopy and light microscopy, and micrographs of relevant morphological details are included. Many of the studied lineages are composed of several identical sequences (SSU), apparently representing groups of clones, sometimes divided by comparatively large distances. A main difference between Ph. pseudonotabile and Ph. notabile is a spore ornamentation, which in the first species is warts irregularly distributed on spore surface whereas the second species has densely spinulose spores. A further difference between these two species is ecological preferences. The first species mainly inhabits in the bark of living plants and ground litter in arid regions, whereas the second ‒ in coarse woody debris in boreal and temperate forests. The delimitation of species supported also well by SSU sequences.
