One of the causes of failure of the cultivation of oyster mushroom (Pleurotus ostreatus (Jacq. Ex Fr) Kummer) is still much contamination baglog inhibit growth and cause failure of oyster mushroom production. For that study was conducted to determine fungal contaminants in the baglog media and inhibiting ability against oyster mushrooms in vitro. Research carried out by the observation methods, sampling randomly contaminated baglog 10-20% of the amount of contaminated baglog, repeated 3 times. Study to be implemented in venture oyster mushroom address: Jl. Siulan gang Zella no. 7 Denpasar, from April to August 2014. The results showed that air-borne fungus could potentially cause failure of oyster mushroom cultivation. The highest prevalence was found in Fusarium spp. (25.6%), while the highest inhibition was found in Mucor spp.(94.7±8.5). Fungal contaminants originating from baglog, the most dominant with the highest prevalence was Trichoderma spp (35.71%). This fungus was very dangerous for the survival of oyster mushroom cultivation.
