LIAN-CHAI SONG's research while affiliated with Guizhou University and other places

A survey of the taxonomy and diversity of freshwater fungi from Karst Plateau wetlands in Guizhou Province, China, three fresh collections were collected from a freshwater river. They have cheiroid, digitate, dictyosporous conidia with one or two hyaline appendages. Phylogenetic analysis of the combined ITS, LSU and tef1-α sequence data support their placement with genera Dictyocheirospora and Dictyosporium (Dictyosporiaceae, Pleosporales). Two collections represent the same species, Dictyocheirospora rotunda. The other collection is introduced as a new species Dictyosporium duliujiangense. An updated phylogenetic backbone tree, descriptions and illustrations of the two taxa are provided for Dictyosporiaceae.

An asexual fungus, collected from diseased leaves of Paphiopedilum sp. from Guizhou Province, China, and based on the phylogenetic analyses and morphological characters, it was identified as a new species in Curvicladiella . The genus Curvicladiella are recorded for the first time for China. The morphology of Curvicladiella paphiopedili sp. nov. is characterised by penicillate conidiophores with a stipe, dull, tapering towards the apex, the curved stipe extension and cylindrical conidia. In the phylogenetic analyses of combined cmdA, his3, ITS, LSU, tef1 and tub2 sequence data, this taxon was clustered as sister to Curvicladiella cignea within Nectriaceae.

Paphiopedilum is known as “slipper orchids”, which has a high ornamental value and can be used as household bonsai and garden plants. Paphiopedilum is also one of the most beautiful plants in the world due to their exotic and unique flowers. An asexual fungus was collected from diseased leaves of Paphiopedilum sp. from Guizhou Province, China, is described and illustrated on the basis of morphological characters and molecular evidence. The morphologies of Curvicladiella paphiopedili sp. nov. were characterized by penicillate conidiophores with a stipe, dull, tapering towards the apex and the curved stipe extension, cylindrical conidia. In the phylogenetic analyses of combined LSU, cmdA, his3, ITS, tef1 and tub2 sequence data, this taxon was clustered as sister to Curvicladiella cignea within Nectriaceae.
