Abstract:
Thaxterogaster is the second largest genus within the family Cortinariaceae, comprising nearly two hundred species worldwide. However, the diversity of the genus in China remains largely unknown. Based on morphological evidence and phylogenetic inference of a five-locus dataset, one hundred twelve species belonging to seven subgenera and 23 sections of Thaxterogaster were analysed. We here describe 15 of those present in China, including 8 species new to science, namely T. crassimultiformis, T. lavendulaceus, T. flavocapitatus, T. pallidopurpurascens, T. atricapitatus, T. cupreus, T. sordidus, T. alboparvus, and 1 species new to China, viz. T. indopurpurascens. Two new combinations, Thaxterogaster subgenus Vibratiles and Thaxterogaster tenuipes, are further introduced. Taxonomic descriptions and a key to the species of Thaxterogaster in Western China are provided.

Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...
