Description of poplar oyster mushroom

The poplar oyster mushroom develops a sporophore, reproductive part visible, pleurotoid in shape. The hat, convex, flattens with age, its size varies from 3 to 9 cm. Grey, brown, cream, it bears vestiges of a veil giving it a mechulous appearance, with large flaps hanging down along the margin. The foot, so short that the hat seems directly attached to its support, also retains the remains of a veil for a moment. As development progresses, the protective veil surrounding the young fungus disappears. The blades under the cap are light in color, beige to cream. They go down on the small end of the existing foot, they are said to be decurrent.
