Pseudorobillarda sichuanensis sp. nov. associated with Bambusa sp. from Sichuan province, China

During an investigation of ascomycetous fungi on bamboos in Sichuan province, China, a new coelomycetous species, Pseu-dorobillarda sichuanensis was found on dead culms of Bambusa sp. and described. The new taxon differs from other Pseu-dorobillarda species in having paraphyses, subcylindrical conidiogenous cells, subcylindrical to naviculate, aseptate, gut-tulate conidia with 3-4 apical appendages. Phylogenetic analyses of a combined internal transcribed spacer (ITS), the partial 28S large subunit rDNA (LSU), the partial 18S small subunit rDNA(SSU) and the partial DNA-directed RNA polymerase II subunit (rpb2) sequence data showed that P. sichuanensis has a close phylogenetic affinity to P. texana. A novel bambusi-colous fungi of Pseudorobillarda is described, illustrated and notes on its identification are provided.
