一种滇产的美味新食菌杨柳田头菇

Agrocybe salicacola, A Delicious Edible Mushroom Newly Discovered from Yunnan

近年来在调查、栽培食用菌的过程中,我们发现一种产于滇中、滇西的美味新食菌,其形态特征及生境与柱状田头菇Agrocybe cylindrica(DC.: Fr.)Maire相似,但因菌盖色浅(幼时也不为深色)、菌褶延生这两个相关性状较为稳定,且其生理特性与柱状田头菇亦有不同,故立为新种,定名为杨柳田头菇A. salicacola Z. L. Yang,Zang et X. X. Liu,考虑到学名的有效、合格发表尚需日时,为便于识别和利用,故先在此作一报道。杨柳田头菇商品名:杨柳菌菌盖宽4—8厘米,初半球形,后伸展至扁平,中部稍下陷,象牙色至米黄色,成熟时中部米黄色,边缘白色,光滑或中部常龟裂,不粘。菌肉白色,不变色,味淡,有香气。菌褶延生,灰褐色,边缘白色,稠密,有小菌褶,宽3—6毫米。

Agrocybe salicacolc, a new species recently discovered from Yunnan is a good edible mushroom. It is closely related to A. cylindrica, but differs in its pale-colored pilei and decurrent lamellae. Attempts have been being made to cultivate this mushroom on a commercial scale.
