The genus Parasola: phylogeny and the description of three new species

ABSTRACT

Parasola represents an enigmatic lineage of veil-less, coprinoid fungi in Psathyrellaceae (Agaricales). The species-level taxonomy of the genus has been in a flux recently, resulting in the elimination of some long-established names and the description of new taxa. Here, we reconstruct the phylogeny of Parasola using two nuc rDNA loci, the internal transcribed spacer region (ITS1-5.8S-ITS2) and 28S and identify several putatively undescribed species, of which three are formally described here (Parasola crataegi, P. ochracea, and P. plicatilis-similis) based on molecular and morphological data. Morphological descriptions for the new species and an identification key to accepted Parasola species are given. We revise and discuss our current understanding of the phylogeny of Parasola.
