polyporus mushrooms

Polypores are a group of tough, leathery poroid mushrooms similar to boletes, but typically lacking a distinct stalk. The technical distinction between the two types of mushrooms is that polypores do not have the spore-bearing tissue continuous along the entire underside of the mushroom. Many polypores are bracket fungi. The polypore growth form exists in many different evolutionary lines of higher basidiomycetes. - There is a border around the image. Image size is correct.
