In the present paper five wild Pleurotus species viz., P. floridanus (Sing.)., P. pulmonarius (Fr.) Quél., P. sapidus Quél., P. cystidiosus O.K.Mill. and P. sajor-caju (Fr.) Sing., collected, identified and isolated from different regions of North West India to study the behavior of culture on solid medium (Potato Dextrose Agar). On the daily basis observations, all the species exhibited different growth characteristics with respect to growth rate, odor and colour. It was observed that among the five cultures the fastest growth was observed in Pleurotus cystidiosus (1.3 cm/day) on an average daily basis followed by Pleurotus pulmonarius (1.23 cm/day), P. sajor - caju (1.2 cm/day), P. sapidus (1.1 cm/day) and P. floridanus (0.8 cm/day) which has the slowest growth rate observed among all the species on an average daily basis. During the entire growth stage the colour of the mycelium remained white. A specialized feature among all the species was observed in P. cystidiosus with the formation of specialized black headed structure called coremia. Coremia formation started in the form of small protuberances on the entire tissue simultaneously. Initially tiny watery droplets having blackish color appeared on the white stalk which after 3 days of protuberance. Mycelial mat was observed to thin at initial stages but later on changing to thick. In all the species the hyphal construction was found to be monomitic having generative hyphae with prominent clamps. All the studied species emitted scented smell
