【 摘 要 】

Twenty samples of compost/substrate from Ukrainian mushroom farms contaminated by green mold have been investigated. After purification and sequencing of isolated DNA fragments, obtained results were compared with GenBank sequences. Among the fourteen samples, the following species of the genus Trichoderma (Pers: Fr.) were identified: Trichoderma atroviride P. Karst., Hypocrea lixii Pat., Hypocrea sulphurea (Schwein.) Sacc., Hypocrea ochroleuca B. & Rav., Trichoderma pleuroticola). The study found that isolated fungal pathogens Hypocrea lixii Pat. and Trichoderma pleuroticola have a close phylogenetic connection with the agents causing epidemic green mold in mushroom farms. The presence of these pathogens represents a critical issue for mushroom farms and a threat to the quality and yield of cultivated mushrooms. Therefore, for understanding the biology of these contaminants it is necessary to study their diversity as well as to establish their ecological and trophic niches in nature.
