Polyporus squamosus (Huds.) Fr.
Polyporus squamosus, is a bracket fungus which is commonly found in North America, Australia, Asia and Europe. This polypore can be found on dead logs and living hardwoods. They can be either saprobic on decaying logs or parasitic on living hardwoods.
P. squamosus has a kidney shaped or fan shaped cap covered with dark brown colored radially arranged scales. The upper side of the body is yellow to brown color and the cap is 5-30 cm across and 1-4 cm thick. The underside of the body is covered by pores which are running down the stem as a tightly packed tube layer. These tubes are up to 1.5 cm long. The fruiting body is attached to the substrate at one point with a thick, 2-8 cm long, off-centered stem (Figure 1). The spore print of P. squamosus is white (Figure 2). Spores are long-ellipsoid and roughly 10-15 x 4-5 µ (Figure 3).
