A total of approximately 104,000 fungal species can be expected in Yunnan. However, approximately 6000 fungal species have been reported from the province leaving much to be described. This study introduces a new species, Fitzroyomyces xishuangbannaensis sp. nov and a new collection of Fit. cyperacearum from Yunnan province, China. The taxa were characterized based on morphological characteristics and combined multi-gene phylogenetic analyses. Both maximum likelihood (ML) and Bayesian inference posterior probabilities (PP) were conducted for combined LSU, ITS and mtSSU sequences data. The new Fitzroyomyces species formed a distinct clade among the extant species of Fitzroyomyces with high statistical supports in the phylogenetic analyses while our new isolate nested together with the corresponding strains of Fit. cyperacearum. A key to Fitzroyomyces species and a synopsis table of morphological characteristics for Fitzroyomyces are provided to support the taxonomic placement.

Alloleptosphaeria shangrilana, collected from dead wood of a dicotyledonous host in Shangri-La, China, is introduced as a new species based on evidence from morphological data and DNA sequence analyses. Maximum likelihood and Bayesian analyses of combined SSU, LSU and ITS sequence data were used to clarify the phylogenetic affinity of the new species. The new taxon is characterized by semi-immersed to superficial ascomata, a thick peridium, branched and septate pseudoparaphyses, cylindrical asci, muriform ascospores and overlapping uniseriate ascospores. Alloleptosphaeria species have been reported from England, Italy, Thailand and this is the first report of the genus in China. A detailed morphological description and analyses of the phylogenetic results are given for the new species. A key and synopsis table to the genus are also provided.
