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

本论文对横断山区隐花植物物种多样性进行了分析，1998年、1999年和2000年，与昆明植物研究所合作开展了”中国植物研究“项目。本项目的主要目的是采集标本用于横断山脉隐花植物物种多样性分析。在调查区共采集隐花植物标本12,000余份，包括苔藓植物、地衣和真菌。收集了大约5,000个标本。高山或亚高山苔藓植物植物群主要由北方成分和部分喜马拉雅成分组成。在温带地区，喜苔科和钩吻科的热带或亚热带种类被认为是沿着分布的。收集了大约3，150个样本。高山或亚高山苔藓植物植物群主要由北方成分和部分喜马拉雅成分组成。在温带地区，喜莲科和钩吻科的热带或亚热带种被认为是沿着分布的。收集了大约4,000个样本。在担子菌门中发现鹅膏菌属（Amanita）和星牛肝菌属（Cinoboletus）两个新种，并鉴定了无褶菌目（Aphyllophorales）的38属87种，其中包括9个亚洲新记录种和37个中国新记录种。此外，还发现了丝齿菌属和管孢菌属两个新种，并鉴定了脲菌纲7个种和黑曲霉纲25个种。在微型真菌和粘菌门中发现了中国新发现的种类，在子囊菌门中发现了中国和日本的肉座菌。从分子植物学的角度来看，形态和分布上存在差异的种或属之间有着密切的亲缘关系。

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.
