    […] One of the most commonly encountered mushroom morphologies is the polypore. Polypores are distinguished by a hymenium (spore-bearing surface) consisting of many, small pores.  Unlike in boletes, the pore surface of the polypores cannot be easily separated from the rest of the mushroom.  Polypores are a highly diverse group of mushrooms that come in a variety of shapes and sizes.  The polypores you are most likely to encounter, especially during the winter, are tough to woody mushrooms that can last throughout the winter.  Of these, the most common are the Turkey Tail (Trametes versicolor) and Trichaptum biforme.  Both of these are medium-sized wood decomposers often found covering fallen logs or stumps.  The tough fruiting bodies are annual, but can last for a year or more.  Other polypores that last through the winter produce large, woody conks on the side of living trees or fallen logs.  These mushrooms are perennial and get larger every year as new layers of pores are added.  Some of the most common woody polypores include the Artist’s Conk (Ganoderma applanatum) and Fomes fomentarius.   In the warmer seasons you can also find many fleshy polypores.  These include the Chicken of the Woods (Laetiporus sulphureus), one of the easiest edible mushrooms to find and identify.  Most polypores are wood decomposers, but a few fill other ecological roles.  Fungi like Fomes fomentarius, Ganoderma applanatum, Grifola frondosa, and Inonotus dryadeus are parasitic to weakly parasitic on their host trees.  Those in the genus Albatrellus are mycorrhizal.
