摘　　要：产自甘肃省冬虫夏草主产区的冬虫夏草具有丰富的形态多样性,少数具有2-4个子座,个别子座叉状分枝。通过移栽培养,对冬虫夏草Ophiocordyceps sinensis子座的发育过程进行了连续观察,并对子囊孢子的萌发及中国被毛孢Hirsutella sinensis的形态特征进行了再研究。观察到:在子囊孢子弹射期,子座可孕部产生明显的缩胀变化;中国被毛孢在培养条件下产生无色和近黑色两种颜色的分生孢子。The stroma of Ophiocordyceps sinensis showed a morphological diversity in major occurring areas of Ophiocordyceps sinensis in Gansu Province,a few samples have 2-4 stromata per endoscle-rotium or form dichotomous stroma.The morpha of developping stroma of Ophiocordyceps sinensis was systematically researched by transplanting culture.The ascospores germination of O.sinensis and the morpha of Hirsutella sinensis were observed.The results show that the fetility part of stroma obvi-ously produces the alternation of contraction and expansion during the stage of ascospore ejection,and the culture of Hirsutella sinensis has two kinds of different color conidia,colorless or near black ones.
