摘　　要：基于蛛网菌属（ＡｒａｃｈｎｏｃｒｅａＭｏｒａｖｅｃ）的模式标本及其所有种的分类特征的研究进一步明确了其系统分类位置及其分类界定；该属是肉座菌科（Ｈｙｐｏｃｒｅａｃｅａｅ）中一个较原始类型。糙孢蛛网菌（ＡｓｃａｂｒｉｄａＤｏｉ）采于云南西双版纳；并与日本（主模式）和新西兰标本及其近缘种的标本作了微、宏观解剖形态学的比较，确定了本种的变异范围。该属的现代地理分布格局表明它是一个北半球温带分布属，然而其分布向南延伸至热带，历史上很可能它是一个东南亚热带起源的属。The taxonomic characteristics and position as well as delimitation of the genus Arachnocrea are discussed. One species Arachnocrea scabrida Doi collected from Xishuangbana Dai Autonomous Prefecture, Yunnan Province, P R China is compared with the specimens from Japan(holotype)and New Zealand as well as other specimens on macro-& micro-morphology and anatomy. The range of variations of this species was defined. It is a new record to China. In spite of the geographical distribution of all species in the genus Arachnocrea in the world shows the modern patterns of the temperate zone in the north hemisphere. It can be stretched to the tropical area of Southeast-Asia, it is possible that the genus was originated in this area historically. It is suggested that the tropical area might be a center of differentiation of species in the genus.
