Twenty samples of compost / substrate from Ukrainian mushroom farms contaminated by greenmold have been investigated. After purification and sequencing of isolated DNA fragments, obtained resultswere compared with GenBank sequences. Among the fourteen samples, the following species of the genusTrichoderma (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 isolatedfungal pathogens Hypocrea lixii Pat. and Trichoderma pleuroticola have a close phylogenetic connection withthe agents causing epidemic green mold in mushroom farms. The presence of these pathogens represents acritical issue for mushroom farms and a threat to the quality and yield of cultivated mushrooms. Therefore, forunderstanding the biology of these contaminants it is necessary to study their diversity as well as to establishtheir ecological and trophic niches in nature.
