杨柳田头菇——无孔组的一个滇产新种

AGROCYBE SALICACOLA, A NEW SPECIES OF SECT. APORUS FROM YUNNAN

近来在研究滇产伞菌的过程中,偶遇一个与柱状田头菇Agrocybe cvlindrica(DC: Fr.)Maire相似的新分类群,为了确证此分类群的可靠性及其系统位置,我们对它作了较详细的野外观察,并将其与柱状田头菇进行了人工裁培对比实验,研究了二者子实体不同发育期的形态特征及颜色变化,确认此新分类群的菌盖色浅(幼时也不为深色)、菌褶延生这两个相关性状是较为稳定的分类特征。此外。

While studying agarics from Yunnan, the authors have found a new fungus similar to Agrocvbe cvlindrica (DC.: Fr.) Maire. Based upon their observations in the field, comparative studies of its cultivation and cultural characters with those of A. cylindrica, a new species, Agrocybe salicacola Z. L. Yang, Zang et X. X. Liu, is proposed for it, which differs mainly in its pale-coloured pileus, decurrent lamellae, and lacking chlamydospores in vitro.
