The re-study for morphology of Ophiocordyceps sinensis and Hirsutella sinensis

Abstract:

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 endosclerotium 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 obviously 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.
