祁连山北麓一种乳牛肝菌的鉴定

Identification of a Type of Suillus sp. from the Northern Foothills of Qilian Mountains

继2018年夏在油松树下发现草黄乳牛肝菌(Suillus stramineus X.F.Shi&P.G.Liu)后,次年夏天,在祁连山北麓人工落叶松林下又发现一种乳牛肝菌,2种乳牛肝菌所处生长气候环境条件基本一致,共生树种不同,形态特点各异;后者因颜色偏灰,并与华北落叶松共生,经初步鉴定为淡灰乳牛肝菌[Suillus grisellus (Peck)Kretzer&T.D.Bruns]。乳牛肝菌类是松、落叶松等针叶树种的外生菌根性共生真菌,是针叶林下常见的大型真菌,往往成片发生,生物量较大,既可食,又可入药,科学利用前景广阔。

After the discovery of Suillus stramineus X.F.Shi&P.G.Liu under the Pinus tabuliformis Carrière in the summer of2018, another species was found in the artificial larch forest at the northern foot of Qilian Mountain in the following summer.The climate and environmental conditions of the two species were basically the same, but the morphological characteristics were different due to the different symbiotic tree species. The latter was identified as Suillus grisellus(Peck) Kretzer&T.D.Bruns by preliminary identification because of its gray color and symbiosis with Larix principis-rupprechtiis. The Suillus spp. is the ectomycorrhizal symbiotic fungus of coniferous species such as pine and larch. It is a common large-scale fungus in coniferous forest. It often occurs in large areas and has a large biomass, which can be eaten and used as medicine.
