Analysis of species diversity of cryptogams in the Hengduan Mts., China

1998年、1999年和2000年与昆明植物研究所合作开展了中国横断山隐子植物物种多样性分析研究。本项目的主要目的是为横断山区隐子植物的物种多样性分析收集样本。从调查地区采集了约1.2万个隐花植物标本，包括苔藓植物、地衣和真菌。共收集了约5,000份标本。在高山或亚高山地带，苔藓植物区系主要由北方成分和部分喜马拉雅成分组成。在温带，沿河分布着热带或亚热带的金鸡儿科和虎眼科植物。共收集了约3150份标本。在高山或亚高山地带，苔藓植物区系主要由北方成分和部分喜马拉雅成分组成。在温带地区，沿河分布着热带或亚热带的金鸡儿科和虎眼科真菌。共收集了约4000份标本。在担子菌纲中发现两个新种：鹅膏菌属和灰霉菌属。共鉴定出寄生真菌38属87种，其中9种为亚洲新记录，37种为中国新记录。还发现了海齿藻和管状藻的两个新种。共鉴定出7种尿链霉菌和25种霉菌。在微型真菌和粘菌纲中发现中国新种和新种。在子囊菌中，利用中国和日本的样品进行了下分泌物种类的检测。从分子植物学的角度来看，表现出形态和分布差异的种或品系之间存在着密切的亲缘关系。

A research entitled "Analysis of species diversity of cryptogams in the Hengduan Mts., China" was carried out in cooperation with the Kunming Intitute of Botany in 1998, 1999 and 2000. The main purpose of this project is to collect samples for the analysis of species diversity of cryptogams in the Hengduan Mts. About 12,000 specimens of cryptogam plants including bryophytes, lichens and fungi were collected from the investigated area.Bryophytes. About 5,000 specimens were collected. In alpine or subalpine zone in the area the bryphyte flora consists of mainly boreal elements and some of Himalayan elements. In temperate zone tropical or subtropical species of the family Calobryaceae and Hookeriaceae were recognized to be distributed along the river.Bryophytes. About 3,150 specimens were collected. In alpine or subalpine zone in the area the bryphyte flora consists of mainly boreal elements and some of Himalayan elements. In temperate zone tropical or subtropical species of the family Calobryaceae and Hookeriaceae were recognized to be distributed along the river.Fungi. About 4,000 specimens were collected. In Basidiomycota two new species of Amanita and Cinoboletus are found. Eighty seven species of 38 genera of corticiaceous fungi(Aphyllophorales) are recognized, among which 9 species new to Asia and 37 species new to China are included. Two new species of Hyphodontia and Tubulicrinis area also found. Seven specoes of Urediniomycetes and twenty five species of Ustilaginomycetes are recognized. In micro fungi and Myxomycota species new to science and new to China are found. In Ascomycota Hypocrea species were examined using samples from China and Japan. Species or straius that show morphological and distributional differences are found to be closely related each other in molecular phytological point of view.
