Neohormodochis septispora gen. et sp. nov. (Stictidaceae) from Yunnan Province, China

Abstract

Stictidaceae has ubiquitous distribution and its members inhabit a wide range of hosts and substrates. However, many genera in this family are represented by a limited number of species and molecular data is lacking for those old genera. Documentation and description of new species is necessary to bring insight into the natural classification of Stictidaceae. An investigation of microfungi in Yunnan Province, China led to the discovery of the novel genus et species, Neohormodochis septispora based on morphological evidence and phylogenetic characterization of combined LSU, ITS, mtSSU and RPB2 sequnces. White-pruinose conidiomata, crystalline conidiomatal wall, cylindrical conidiogenous cells and dominantly sepate conidia arranged in branched chain characterize the novel genus. The phylogenetic placement of Dendroseptoria was uncertain and in this study, we confirmed its placement in Stictidaceae based on the phylogenetic affiliation of D. mucilaginosa.
