Novel myrothecium-like species identified in Oryza sativa, suggesting rich fungal diversity in Yunnan.
During a survey of endophytic fungal diversity in Oryza sativa, a novel myrothecium-like taxon, Alfaria yunnanensis, was collected from Yunnan, PR China. This novel species is characterized by having sporodochial conidiomata, septate conidiophores, phialidic conidiogenous cells and cylindrical-to-fusiform conidia. Phylogenetic analysis of the combined sequences of the internal transcribed spacer region (ITS), the RNA polymerase II second-largest subunit (rpb2), calmodulin (cmdA) and β-tubulin (tub2) confirmed that the myrothecium-like taxon represents a novel member of the genus Alfaria. A full description, illustration and a phylogenetic tree showing the position of A. yunnanensis are provided.
