Two New Species of Trichoderma Associated with Green Mold of Oyster Mushroom Cultivation in Korea

摘要

This paper describes and illustrates two new species, Trichoderma pleurotum and T. pleuroticola, associated with green mold disease of oyster mushroom in Korea. Oyster mushroom (Pleurotus ostreatus) production in Korea has increased rapidly since theearly 1980s. It is now one of the most valuable horticultural enterprises in Korea. During the last 10 years, however, commercial production of oyster mushroom has been seriously affected by green mold epidemics. The typical symptoms of the green mold are the appearance of green fungal sporulation on oyster mushroom substrates. In severe outbreaks, no mushrooms are produced from the contaminated beds (Park et al., 2005a; Yu, 2001).
