Abstract
ABSTRACT Type specimens of four species of Lepidoderma (Myxomycetes, Amoebozoa)—L. crassipes, L. neoperforatum, L. perforatum, and L. stipitatum—have been studied using an integrative approach including application of traditional taxonomy methods, i.e., morphological study under stereoscopic and compound microscopes, detailed analysis of micromorphological characters using scanning electron microscopy, and molecular analysis by way of Sanger sequencing of molecular markers (nuc 18S rDNA and elongation factor 1-alpha gene, EF1A). Results of the study revealed that L. crassipes is conspecific with L. tigrinum, L. stipitatum is a malformed specimen of Diderma floriforme, whereas L. perforatum and L. neoperforatum represent two well-defined morphologically and genetically separate species. Phylogeny of Physarales shows the polyphyletic character of the genus Lepidoderma. The type species of Lepidoderma clusters together with Diderma, whereas other representatives of this genus form a monophyletic, well-supported clade. The species from this clade are proposed to belong to the genus Polyschismium described by A. Corda in 1842 that is resurrected and emended here. Nine species of Lepidoderma are transferred to Polyschismium. A new key to Didymiaceae including Polyschismium is provided.
