Abstract
A new widespread myxomycete species, Physarum pseudonotabile, inhabiting the arid regions of the Eurasia, South and North America is described and illustrated. Tentatively assigned to Ph. notabile T. Macbr., a phylogeny based on the small ribosomal subunit (SSU) and elongation factor 1 alpha (eF1a) genes placed the new species in a clade far apart from Ph. notabile and revealed a considerable molecular diversity within this clade. Ph. pseudonotabile was found to be very frequent in surveys based on the moist chamber culture technique with samples of litter, bark and herbivore dung collected in dry steppe and deserts of the Caspian lowland (Russia), Kazakhstan, Mongolia, China, Spain, Argentina and USA. The main morphological difference between Ph. pseudonotabile and Ph. notabile lies in spore ornamentation. Spores of the former species display irregularly distributed verrucae, whereas the latter species possesses spores with dense and regularly arranged spinulae. In addition, the ecological preferences of the two species are different: Ph. pseudonotabile inhabits the bark of living plants and ground litter in arid regions, whereas Ph. notabile is found on coarse woody debris in boreal and temperate forests. Although morphologically the new species appears to be closest to Ph. notabile, SSU and eF1 alpha gene-based phylogeny showed Ph. pusillum (Berk. & M.A. Curtis) G. Lister and Ph. nivale (Meyl.) M. Mey. & Poulain as the closest relatives, but also reveal a considerable amount of hidden diversity within species of Physarum showing gray lime flakes. Currently, we have only sufficient material to assess the morphological variation of Ph. pseudonotabile, but expect that more taxa within this clade may be described within future studies combining morphological with molecular analyses.
