Polypore variable
Polyporus varius (Pers.) Fr. 1821
50.8843, 5.98617
Field Notes
Description:
Typically fruiting on smaller hardwood sticks and decaying branches, this polypore is easily recognized by its fairly small size, its whitish pore surface, and its black, or half-black, central stem. It is widely distributed across North America, and appears to vary somewhat in the color and texture of its cap. Like many polypores it is rather tough, and can manage to "stay up" for quite a while in dry weather--resulting in older specimens with faded, nearly white caps and sordid brownish pore surfaces
