Three species of Oyster mushroom viz. Pleurotus ostreatus, Pleurotus sajor-caju, Pleurotus florida were procured from DMR, Solan and a wild strain was collected from Bankura district in West Bengal during the monsoon season of 2017-18. The effect of temperature and pH on mycelial growth of different Pleurotus spp. and a wild collected strain was observed at temperatures 20°C, 25°C, 28°C and 32°C and pH 4.5, 5.5, 6.5,7, 7.5 and 8.5. The study revealed that a temperature of 25 ºC was optimum for most of the Pleurotus isolates on PDA plates. Although, the collected strain showed the restricted mycelial growth of 3.20 cm after 5 and 7 days of inoculation at 28°C. Also, a pH range of 6.5 to 7.5 was found to be optimum for P. ostreatus, P. sajor caju and P.florida while the wild collected showed optimum mycelial growth at an acidic pH 4.5-5.5 on PDA plates.
