Аннотация: The order Physarales is the largest and the best studied group of myxomycetes, orplasmodial slime molds, distinguished on the basis of the morphology of fruitingbodies (sporophores) and molecular data. However, the structure of the order, aswell as the boundaries separating its families, becomes a hot issue in the context ofcurrent phylogeny reconstructions. To solve the issue of the systematic position of thegenus Kelleromyxa Eliasson, we carried out low-pass genome sequencing («genome skimming»), which allowed us to obtain contigs suitable for two-gene phylogeny reconstruction. Different methods of phylogeny reconstruction showed the same result: the genus Kelleromyxa cannot be clearly assigned to one of the families in the order Physarales, but assumes an intermediate position between Didymiaceae and Physaraceae. In turn, the topologies and statistical support of Maximum likelihood and Bayesian inference phylogenetic analyses clearly indicate the paraphyletic nature of both families, which only reinforces the conflict of morphological and molecular genetic concepts of taxa in myxomycetes.
