Extract from Wikipedia article: 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.
Strobilomyces strobilaceus is a species of bolete fungus characterized by its dark brown to black cap, white pores, and reticulate stalk pattern. In East and Central Texas, it typically fruits from June to October, often in association with oak and pine trees. The fungus can be found in wooded areas, particularly under mature trees, and tends to favor well-drained soils and slightly acidic to neutral pH. Fruitbodies are generally solitary or scattered, with caps ranging from 3-8 cm in diameter. Spores are dark brown, measuring 10-14 μm in length, and have a distinctive verrucose surface.
