Oyster mushroom commonly known as “Dhingri” is a delicate and nutritious mushroom that is grown and consumed as a food item. Morphology and nutritional contents are highly influenced by climatic conditions as well as the quality of the substrate. The most important Pleurotus species that grow naturally in abundance are Pleurotus ostreatus, Pleurotus Florida, Pleurotus flabellatus, and Pleurotus sajor cajun. In present study, the morphological characteristics of three Pleurotus species viz., Pleurotus sajor cajun, Pleurotus Florida, and Pleurotus djamor, were studied. Six different morphological features i.e., stipe size (cm), pileus size (cm), pileus shape, colour of fruiting body, lamellae and spore shape and size (µm) were recorded. The results suggest that the morphological characteristics of all three Pleurotus species share many similar features and hence belong to the same genus.
