context_page_description: Strobilomyces strobilaceus, also called Strobilomyces floccopus and commonly known as old man of the woods, is a species of fungus in the family Boletaceae. It is native to Europe and North America. Fruit bodies are characterized by very soft dark grey to black pyramidal and overlapping scales on the cap surface.
context_section_description: The caps of the fruit bodies are between 4 to 10 cm (1.6 to 3.9 in) wide, with a convex shape and a villous, involute margin. The cap surface is covered with dark grey to black erect scales. The stipe is up to 14 cm (5.5 in) long and 2 cm (0.8 in) thick. It is coloured like the cap and has a woolly surface and a thick, ascending annulus. The pores on the underside of the cap are hexagonal, coloured dirty white or grey. The flesh is thick and initially white, but will stain pink and then slate grey and black after exposure to the air. The taste of the mushroom is indistinct, with a slight earthiness. 
  The dark brown to black spores are 9–15 by 8–12 μm, short elliptic and are covered with a mesh-like ornament.
