About Boletopsis grisea (Peck) Bondartsev & Singer
Boletopsis grisea produces fleshy, ground-growing polypore fruit bodies. Its gray cap is convex, irregular in shape, and has a dry surface, reaching up to 15 centimetres (6 inches) wide. The stem of the fruit body measures 3–10 cm (1+1⁄4–4 inches) in length. The stout stipe matches the cap in color, and white pores are located beneath the cap. The flesh is whitish, and changes color to gray or greenish when bruised or exposed. This species has a fragrant smell, and produces a tan spore print. Boletopsis grisea occurs in Europe, Canada, and the United States. Fruiting occurs from August to October in eastern North America, and from September to November in western North America. It grows on nutrient-poor acidic soils, and forms mycorrhizal associations with Pinus sylvestris (Scots pine), in habitats with lichens and heath plants as understorey.
