西昆仑山区高等真菌的研究

NOTES ON THE FUNGI FROM WESTERN KUNLUN MOUNTAINS

本文报道了西昆仑山区和喀喇昆仑山区高等真菌39种,其中我国新纪录4种。

In 1987, one of the authors has been joined a mycological expedition to Western Kunlun Shan (Mountains) and Karakorum Shan (ca. 35°9'-39°80' N, 74°40'-77°10' E) led by Academia Sinica. This region is a high plateau in the world, it is interspersed by a series of snow-capped, an extremely highest Qogir Feng (Mt. K2; Godwin Austen) is situated there, it above 8611 m in elevation. In the more arid places, the number of fungal species is fewer and sometimes pure course association were observed. About 3000-3500 m alt. where extend conifers forest, several genera of Agaricales are found here and dominated by Picea sche-nkiana, especially in little wet gullies and humid, fog-exposed sites, which abound in different species of Agaricus, Lyophyllum, Leucopaxillus, Entoloma etc. The mycoflora is poor in species in the montane desert-steppe and alpine desert, this is apparently due to the quite arid contnental climate. The following records new to China, e. g. Fernsjonia altaica, Clitocybe altaica, Melanoleuca subalpina and Psilocybe rnontana. Pastures and alpine meadows offer a wide selection of easily identified edible mushrooms, notably Agaricus gennadii, Lyophyllum loricatum etc. an endemic delicious species Pleurotus ferulae, it usually scattered or in groups under or near the root of Ferula sinkiangensis.
