Species diversity of Hygrophorus(Hygrophoraceae,Agaricales)in Shanxi Province and description of Hygrophorus brunneodiscoides sp.nov.
[Background]Hygrophorus,belonging to Basidiomycota,Agaricomycetes,Agaricales,Hygrophoraceae,is widely distributed all around the world.[Objective]To investigate the species of Hygrophorus and enrich the knowledge about the species diversity of this genus in Shanxi Province.[Methods]We collected fungal specimens,observed and characterized their morphology.After DNA extraction,the internal transcribed spacer(ITS)was sequenced.Phylogenetic trees were constructed based on the maximum likelihood method and Bayesian inference.[Results]Eleven species of Hygrophorus were identified based on the morphological and molecular evidence,including ten known species and a new species.This article described the macroscopic and microscopic morphological characteristics of the new species Hygrophorus brunneodiscoides in detail.The basidiocarp photos of ten known species and a key to the species of Hygrophorus in Shanxi Province were provided.[Conclusion]We identified a new species,H.brunneodiscoides,in China,confirmed 11 species of Hygrophorus in Shanxi Province,and briefed their geographical distribution and associations with hosts according to the field observation.
