Abstract： This study investigated eight edible mushroom species from the Arshan area，analyzing their contentof nine organicnutritionalcomponents，includingcrudeprotein，totalsugar，andcrudefat，aswellascrudeashandsixorganic mineral elements.Principal component analysis （PCA）and cluster analysis wereemployed to comprehensively evaluate the nutritionalqualityoftheseeight mushroom species.Theresults showed that thecoefficientsof variationforthe15 nutritional componentsranged from 9.45% to 114.37% .Specifically，thecoefficientsof variation forchlorineand starch content were 114.37% and 100.64% ，respectively， indicating significant differences in nutrient content among the eight species.In the PCA，the cumulative contribution rate of the first two principal components reached 90.955% ，representing the majority of the nutritionalquality data.The comprehensive scores of theeight mushroom species ranged from -2.407 to1.741.Among them，Calocybegambosaachievedthehighestscore，indicating the bestoverallnutritional quality.Hypsizygus marmoreus，Tricholomamongolicum，ndStrophariarugosoannulatascoredbetween.083and1.244，eoting relativelygood nutritional quality.Incontrast，Pholiota namekohadthe lowestscore，signifying poorer nutritional quality. Clusteranalysis clasifiedtheeight mushroomsamples intofour distinctclusters：ClusterIcontained twosamples，Cluster II contained four samples，Cluster IIcontained one sample，and Cluster IVcontained one sample.Hypsizygus marmoreusand Calocybe gambosa were grouped together，primarilycharacterized by their high content ofcrude protein， crudefat，total fatyacids，andmagnesium，identifyingthemashigh-qualityedible mushrooms.Inconclusion，theresults ofPCAand clusteranalysis wereconsistent，with Calocybegambosademonstratingthebestcomprehensivequality.The findingsof this studyprovideascientificreferenceforthe developmentand enhancementoftheedible mushroom ndustry in the Arshan area.
