榆耳是一种野生真菌,其子实体食之,质如海参,煎汁可治疗痢疾和肠胃系统等疾病,经中科院沈阳应用生态研究所王云先生鉴定,榆耳属多孔菌目,伏革菌科,胶韧革菌属的真菌,仅分布在中国东北地区和日本。1984年我们在辽宁省铁岭地区采集到该菌,经组织分离获得纯菌株。为了开发这一食药用菌资源,我们对其进行了人工驯化栽培,现将结果简报如下:(一)形态特征:野生榆耳常腐生在榆树枯死的树干上,每年八、九月是子实体大量发生季节.子实体原基呈球形或平伏,开片后呈耳或扇形。菌盖表面被覆一层浓密绒毛,子实体单生或丛生,无柄,胶质、半透明,幼嫩时粉红色,老熟后变为黄褐色。孢子印白色,孢子椭圆形至腊肠形,光滑,2.5～
Elm is a wild fungus, its fruiting bodies of food, quality, such as sea cucumber, fried juice can treat dysentery and gastrointestinal diseases, the Chinese Academy of Sciences Institute of Applied Ecology, identified as Mr. Wang Yun, Mycoplasma, Daphnia genus of fungi, only distributed in northeast China and Japan. In 1984, we collected the strain in Tieling, Liaoning Province and obtained pure strains by tissue separation. In order to develop this medicinal and medicinal resources, we conducted artificial domestication and cultivation. We will present the results as follows: (1) Morphological characteristics: wild elm ear often saprophytic in the dead elm tree trunk, each year in August and September is a child A large number of entities occur season .Subject entity spherical or flat base, after the opening was ear or fan. Caps covered with a layer of dense villi, fruiting bodies solitary or clustered, sessile, glial, translucent, young pink, yellowish brown after aging. Spores printed white, spores oval to sausage-shaped, smooth, 2.5 ~
