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

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.

Automated summary

Stictidaceae has a wide distribution and can be found on various hosts and substrates. However, there is limited information and molecular data for many genera in this family. A new genus and species, Neohormodochis septispora, was discovered in Yunnan Province, China through an investigation of microfungi. The phylogenetic characteristics and morphology of this new genus were analyzed, and the placement of Dendroseptoria in Stictidaceae was confirmed.
