Neomonodictysaquatica sp. nov. (Pleurotheciaceae) from a plateau lake in Yunnan Province, China

BACKGROUND: In this study, a new species Neomonodictysaquatica was collected from submerged decaying wood in Erhai Lake, Yunnan Province, China. NEW INFORMATION: Neomonodictysaquatica is characterised by acrogenous, solitary, oval, dictyospores (most are transverse septum, occasionally vertical septum, in immaturity the septum is clear, but when mature, the conidia becomes darker so the septum is not clear), smooth-walled conidia. The immature conidia are usually hyaline to olivaceous and mature conidia are usually darkened to black, sometimes with one pale basal cell. Phylogenetic analyses of combined ITS and LSU sequence data showed that the new collection is distinct from other Neomonodictys species. Description and illustration are provided as well.
