中国绒泡菌属的分类学研究II.产自新疆的新种和稀有种

关于新疆的粘菌，过去仅知８种，且无一为绒泡菌。本文第一作者于１９９４年在新疆进行了粘菌资源调查，在随后的研究中共明确了５０多个种，有１０种为绒泡菌，其中的几个种，如垂头绒泡菌Ｐｈｙｓａｒｕｍｎｕｔａｎｓ（Ｂｕｌｌ．）Ｐｅｒｓ．是常见和广布的，但也有几种是特殊的和稀有的。本文报告了５种绒泡菌：橙红绒泡菌Ｐ.ａｕｒａｎｔｉａｃｕｍ　Ｓ．Ｌ．Ｃｈｅｎ，Ｙ．ＬｉｅｔＨ．Ｚ．Ｌｉ和侧扁绒泡菌Ｐ．ｌｏｒａｔｕｍＳ．Ｌ．ＣｈｅｎＹ．Ｌｉ　ｅｔＨ．Ｚ．Ｌｉ是新种，黄白绒泡菌Ｐ．ａｌｂｅｓｃｅｎｓＥｌｌｉｓｅｘＴ．Ｍａｃｂｒ．和团聚绒泡菌Ｐ．ｃｏｎｇｌｏｍｅｒａｔｕｍ（Ｆｒ．）Ｒｏｓｔａｆ．是中国新记录种，已知种黄绿绒泡菌Ｐ．ｖｉｒｅｓｃｅｎｓＤｉｔｍａｒ显然少见，国内此前仅知分布于福建。橙红绒泡菌Ｐ．ａｕｒａｎｔｉａｃｕｍＳ．Ｌ．Ｃｈｅｎ，Ｙ．ＬｉｅｔH.Ｚ．Ｌｉ的孢丝近似钙丝菌状，由或大或小的石灰结将许多细短的孢丝线联成致密的白色网体，这使其被归入绒泡菌属，并与同属其它种相区分；侧扁绒泡菌Ｐ．ｌｏｒａｔｕｍＳ．Ｌ．Ｃｈｅｎ，Ｙ．ＬｉｅｔＨ．Ｚ．Ｌｉ的联囊体虽发达而侧扁，但顶部无预成开裂线，在相似种中也易识别。本文对这两个新种

TAXONOMIC STUDIES ON PHYSARUM FROM CHINA II.NEW AND RARE SPECIES FROM XINJIANG

Five species of the genus Physarum from Xinjiang are reported herein. Two speciesnew to science (viz. P. aurantiacum S. L Chen, Y. U et H. Z. Li and P. loratum S. L. Chen, Y.Li et H Z. U) are described, illustrated and discussed. Two first recorded specties for China (i. e.P. albescens Ellis ex T. Macbr. and P conglomeratum (Fr.) Rostaf.) and another known species (P.virescens Ditmar) are discussed. The specimens cited are deposited in HMAS, Bejing.
