Hypocrea disease is the most severe disease of oyster mushroom cultivation in Korea. Physiological and ecological studies were performed on the pathogens (Hypocrea spp.) to obtain basic information for developing the integrated disease management system. Fourteen isolates of Hypocrea were collected from oyster mushroom house in five areas. Pathogenic fungi causing disease of oyster mushroom were identified as Hypocrea sp. based on morphological characteristics and pathogenicity. Two isolates (H-1, H-12) showed the fastest growth at 15oC but four isolates (H-8, H-9, H-13, H-14) showed slower growth than those of other isolates at 20oC and 25oC. Stroma with ascocarps and ascospore were produced on PDA under fluorescent light. The five isolates produced stroma with ascocarps and ascospores. Formation of fruiting body of strains H-14 of Hypocrea were the best out of all the strains on the potato dextrose agar (PDA). Also, fruiting bodies and ascospores were completely produced under fluorescent light. The growth of the isolates was correlated with total carbon content. The stroma of the isolates was formed mainly in histidine and asparagine treatment and especially in histidine-70 and asparagine-100 treatment. In the test of pathogenicity, after and before spawning showed very fast incidence of disease.
