Cordyceps sinensis, a caterpillar entomopathogenic fungus-host larva complex, is a rare medicinal herb found in the Qinghai-Tibetan Plateau and its surrounding @entity2222 areas. The alternation of generations in the life cycle, whatever the fungus or its host insect, requires special growth conditions. However, it is difficult to simulate the growth conditions of @entity2441 , which hinders its artificial cultivation. In this work, the life cycle from the host larva to @entity2441 was observed in an indoor-cultivation laboratory at 4,200 m a.s.l. on Sejila Mountain, Tibet. Comparative examinations between indoor-cultivated and wild @entity2441 demonstrated that the indoor-cultivated @entity2441 preferred to germinate multiple long, slim stromata at diverse positions on dead larvae, including but not limited to their heads. Their @entity844 composition shows a significant difference in the levels of @entity1474 ( @entity5204 ). In indoor-cultivated @entity2441 , @entity5204 constituted 24.59% and 49.43%, respectively, of neutral and polar lipids; meanwhile, in wild @entity2441 , @entity5204 represented 34.34% and 61.25% of neutral and polar lipids, respectively. These observations and @entity844 data suggest that environmental factors, particularly temperature, soil pressure and light intensity, strongly affect the growth of @entity2441 . Our new findings may provide important information for improving techniques for the large-scale artificial cultivation of @entity2441 .
