摘要
对产于陕西省的腹菌纲（Ｇａｓｔｅｒａｍｙｃｅｔｅｓ）真菌，共４２个ＯＴＵ’Ｓ和３６个性状，进行了Ｑ模式聚类分析，结果表明：（１）４２个ｏＴＵ’Ｓ明显的分为六大类群，与Ｄｒｉｎｇ（１９７３）系统的６个目相吻合。（２）栓皮马勃属（Ｍｙｃｅｎａｓｔｒｕｍ）与灰包科（Ｌｙｃｏｐｅｒｄａｃｅａｅ）中包被具拟薄壁层的属相似性较小，支持Ｈａｗｋｓｗｏｒｔｈｅｔａｌ（１９８３）将其作为科级处理的观点。（３）作者认为鬼笔属（Ｐｈａｌｌｕｓ）和竹荪属（Ｄｉｃｔｙｏｐｈｏｒａ）作为两个独立属处理比较合适。
OTU’S and 36 characters of Gasteromycetes from Shaanxi Province were analyzed by us-ing cluster. The results show that:(1)42 OTU’S were divided into 6 groups and this fitted tothe 6 orders of Dring(1973) ystem. (2)It has been verified that the order Phallales is a naturaltaxonomic group.(3)It is reasonable that Phallus and Dictyophora are two distinguished genera. And(4)There is smaller similarity between Mycenastrum and the other genera of Lycoper-daceae. This point supported the systematic arrangement of Hawksworth et al.(1983).
