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.
