Morphological and phylogenic appraisal of a novel species and a new record of Fitzroyomyces in Yunnan Province, China

Stictidaceae species have diverse lifestyles and are distributed worldwide. Recent studies resulted several new and interesting Stictidaceae species from China. In this study, we introduced a new species, Fitzroyomyces filiformis as well as a new host record of F. pandanicola from Yunnan Province, China, based on the evidence from morphological and phylogenetic characterisations. The phylogenetic analyses were estimated for maximum likelihood and Bayesian inference analyses based on ITS, LSU, and mtSSU sequence data. In this study, we introduce a new species from Yunnan Province, China, Fitzroyomyces filiformis, phylogenetically having a sister relationship to F. hyaloseptisporus, a species from which it differs in ascus and ascospore size. Sapindus delavayi is reported as a new host of F. pandanicola. We also provided the updated synopsis for Fitzroyomyces.
