CLUSTER ANALYSIS OF THE SPECIES OF THE GENUS USTILAGO
黑粉菌属的聚类分析

A hierarchical clustering analysis was tried with 51 species-specimen under the genus Ustilago hitherto collected and identified from China by many authors.The result was based on 33 morphological and biological coding characters as well as with group-average method.From the result of the cluster analysis,the 51 species-specimen under Ustilago were divided into 3 phenons.Ustilago esculenta P.Henn.was more reasonable to be kept under this genus,instead of a new one Yenia.Ustilago ocrearum was like to be a variant of Ustilago koenigiae,while Ustilago kusanoi was like to be a variant of Ustilago minima.
