Mushrooms with a "pleurotoid" habit grow on wood, have gills, and typically form semicircular or kidney-shaped caps that are either directly attached to the wood or are attached by means of a rudimentary, lateral stem. They often grow in loose or dense clusters, forming shelf-like groups. However, many pleurotoid mushrooms can develop more or less central stems, especially when they grow on the upper surface of a log—when the stemless, sideways fruiting strategy would not allow the mushroom to hold its gills so that the spores will catch air currents and be distributed.
Pleurotoid mushrooms do not form a group of naturally related mushrooms; it is simply convenient, when identifying mushrooms, to narrow down the possibilities by lumping them together. Species of Crepidotus, for example, have brown spore prints and belong in the family Inocybaceae—while the "oyster mushroom," Pleurotus ostreatus has a lilac spore print and belongs in an entirely different family, the Pleurotaceae.
