The antagonistic/antifungal activities (AA/AFA) of the higher Basidiomycetes medicinal mushroom Pleurotus tuberregium were studied in a dual-culture experiment using potato-dextrose agar at two different temperatures (26°C and 30°C) against phytopathogens (Fusarium culmorum, Bipolaris sorokiniana) and their antagonists (Trichoderma harzianum, T. asperellum). Keratino-philic species Chrysosporium keratinophilum and Microsporium gypseum, which are potential pathogens for humans and animals, were also tested. Interspecies interactions previously described in the literature were used for estimating the AA/AFA of contacted fungal organisms in Petri dishes. Results indicated that high temperature typically stimulates the growth rate and antagonistic activity of Pleurotus tuberregium, particularly against Fusarium culmorium and Trichoderma harzianum. Mycelium of Pleurotus tuberregium was able to completely overgrow the keratophilic fungus Chrysosporium keratinophilum, but it had less antagonistic effect against Microsporium gypseum. Pleurotus tuberregium markedly inhibited the growth of tested phytopathogenic fungi and their antagonists. Among them, Fusarium culmorum, Trichoderma harzianum, and T. asperellum expressed more antagonistic activity toward Pleurotus tuberregium. Activity of Pleurotus tuberregium against Trichoderma harzianum and Fusarium culmorum at 30°C was significantly higher than at 26°C. Trichoderma harzianum may not be able to cause economic loss in the commercial cultivation of Pleurotus tuberregium.
