Painted Suillus

Suillus spraguei is a species of fungus in the family Suillaceae. It is known by a variety of common names, including the painted slipperycap, the painted suillus or the red and yellow suillus. Suillus spraguei has had a complex taxonomical history and is also frequently referred to as Suillus pictus. The readily identifiable fruit bodies have caps that are dark red when fresh, dry to the touch, and covered with mats of hairs and scales that are separated by yellow cracks. On the underside of the cap are small, yellow, angular pores that become brownish as the mushroom ages. The stalk bears a grayish cottony ring and is typically covered with soft hairs or scales. The species bears a resemblance to several other members of Suillus, including S. decipiens, but can be differentiated by variations in color and size.
