摘　　要：本研究选取了《中国真菌志?第二十七卷?鹅膏科》中27个物种及变种,对这些分类单元的菌托形状、菌褶颜色、担子大小等形态学特征进行统计,依据这些形态学特征进行主成分和聚类分析,得到各物种及变种与各个形态学特征之间的关联程度。通过聚类分析将27个物种及变种分为四大类,最终结果与鹅膏属分类情况一致,验证了上述分析方法在鹅膏属分类研究领域具有可行性与准确性。Morphological characteristics of 27 species and varieties of Amanitaceae recorded in Flora Fungorum Sinicorun Vol. 27 including characteristics of volva, gill, basidium and so on are analyzed using principal component and cluster analysis. The 27 species and varieties are divided into four classes by cluster analysis. The results are consistent with general morphological identification of Amanita.
