title: Fruiting Body Production of the Medicinal Chinese Caterpillar Mushroom, Ophiocordyceps sinensis (Ascomycetes), in Artificial Medium.
abstract: Ophiocordyceps sinensis (syn. Cordyceps sinensis), regarded as the "Himalayan Viagra", is widely used for medicinal treatment and health foods. The price of O. sinensis has continued to increase over the past few years because of the growing worldwide demand and resource limitations. Artificial cultivation of the fruiting bodies to substitute natural O. sinensis is urgently needed for the effective protection of a valuable bioresource and environment in the Tibetan plateau, and for commercial trade. In this study, the anamorph of 3 isolates was separated from natural O. sinensis and identified by molecular markers as Hirsutella sinensis. These fungal isolates were cultured in a rice-based medium at 9-13 °C for 50 days for mycelial growth, at 4 °C for 100 days for stromatal induction, and at 13 °C for 40 days for fruiting body formation. The mature fruiting bodies with mature perithecium were harvested in about 140 days. This is, to our knowledge, the first report of stable fruiting body production of O. sinensis by artificial media in the low-altitude area outside the Tibetan plateau.
