滇西北地区羊肚菌子囊果形态多样性研究

A Study on the Ascocarps Morphology Diversity of Morchella from Northwest Yunnan Province

对采集自滇西北地区的羊肚菌、高羊肚菌、黑脉羊肚菌和尖顶羊肚菌的子囊果形态(包括鲜重、总长、菌柄长、菌柄直径、菌帽长、菌盖直径、菌柄与总长的比率、菌盖与总长的比率、菌盖与菌柄的比例)进行了测量和统计分析。结果显示,每种羊肚菌均有自己独特的形态特征,不同形态特征具有不同的变异大小,但有些形态呈连续过渡状况并且受到环境的影响显著。此研究结果对深入研究羊肚菌属种类的亲缘关系与分化具有一定的意义。

The ascocarps morphology including fresh weight, total length, stipe length, stipe diameter, pileus length, pileus diameter, ratio of stipe length to total length, ratio of pileus length to total length, ratio of pileus length to stipe length and color of 4 Morchella species, i.e. M. esculenta, M. conica, M. angusticeps and M. elata which collected from northwest Yunnan province has been measured and analyzed. The result demonstrates that each species has its own unique morphology, but some characters are in grades and strongly influenced by environments.
