Background: Based on unique morphological features and phylogenetic analysis of combined LSU and ITS sequences, Paramirandinaguttulata is established as the third species in Paramirandina, along with P.aquatica and P.cymbiformis. All three species of Paramirandina were reported from freshwater habitats in China.
New information: Paramirandinaguttulata sp. nov. is a morphologically conspicuous hyphomycetes species, collected from a plateau lake (Dujuanhu Lake) in Yunnan Province, China. The key distinguishing characteristics of P.guttulata are scattered or gregarious conidiophores, polyblastic, terminal, sympodial conidiogenous cells and fusiform, cymbiform, 4-6-septate, guttulate, hyaline conidia that are solitary or in chains and with truncate base and obtuse apex. Detailed descriptions and illustrations are provided for the new species.
Keywords: Dothideomycetes; hyphomycetes; new species; phylogeny; taxonomy.
