Two new species of Jalapriya and a new record, Dictyocheirospora vinaya from freshwater habitats in China
Pleosporales is the largest order of Dothideomycetes. In recent years, systematics of Pleosporales have undergone considerable revisions. Dictyosporiaceae is one of the newly established families within this order proposed to accommodate holomorphic saprobic Dothideomycetes. Currently 18 genera are recognised in Dictyosporiaceae.The new species, Jalapriya aquaticum sp. nov. and J. apicalivaginatum sp. nov. were collected from freshwater habitats in Gansu and Yunnan Provinces, China, respectively and are introduced, based on morphology and molecular analysis of combined ITS, LSU, SSU and TEF1-α sequence data. We also recovered one fresh collection of Dictyocheirospora vinaya D’souza, Bhat & K.D. Hyde, which is a new record for China. Jalapriya aquaticum differs from extant species of Jalapriya in rows converging at the apex and apical cells with spherical-like appendages. Jalapriya apicalivaginatum differs from extant species of Jalapriya in having the rows of conidia mostly arranged in a plane. The phylogenetic analysis place the new collections within Dictyosporiaceae (Pleosporales). Descriptions and illustrations of Jalapriya aquaticum, J. apicalivaginatum and Dictyocheirospora vinaya are provided. A synopsis of characters of species of Jalapriya is also provided.
