原块菌属的分类界线及其地理分布

报道了原鬼笔科Ｐｒｏｔｏｐｈａｌｌａｃｅａｅ我国的一个新记录种──日本原块菌ｐｒｏｔｕｂｅｒａｎｉｐｐｏｎｉｃａＫｏｂａｙ．，原记载其分布于日本，近来在我国云南南部发现，属于东亚特有分布种。并讨论了原块菌属ＰｒｏｔｕｂｅｒａＭｏｌｌｅｒ的分类界线，同意前人把ＰｒｏｔｏｐｈａｌｌｕｓＭｕｒｒｉｌｌ、ＰｒｏｔｕｂｅｒｅｌｌａＩｍａｉｅｔＫａｗａｍｕｒａ和ＫｏｂａｖａｓｉａＩｍａｉｅｔＫａｗａｍｕｒａ作为原块菌属的异名；亦根据现代地理分布格局推断原块菌属原是一个热带、亚热带分布属。

TAXONOMIC LIMITS OF THE GENUSPROTUBERA AND ITS GEOGRAPHICAL DISTRIBUTION

species Protubera nipponica Kobay.of family Protophallaceae is reported and illus-trated from China for the first time. It has been found in Japan and Southern Yunnan of China,and it may be an endemic species of the Estern Asia according to the present data. This paper al-so discusses the taxonomic limits of genus Protubera Moller and places Protophallus M urrill, Protuberella Imai et Kawamura and Kobayasia Imai et Kawamura into the genus Protubera as its synonyms.Protubera may be inferred the genus of the tropical and subtropical distribution origi-nally from the modern geographic distributional patterns of the most species.
