The common deformed mushrooms mainly include the following types: 1. Hollow stipe. From the outside the mushroom looks normal, but when the base is cut off, part of the stipe is found to be hollow, usually with a ring-shaped cavity around a hard core. Afterwards, the cut surface of the stipe may split and curl backward, making the mushroom poor in appearance and reducing its marketability.
