Entoloma bloxamii is a large, sticky, bluish gray to purplish gray entolomatoid mushroom, reminiscent of a Tricholoma in stature. The version of Entoloma bloxamii featured here is from the West Coast of the United States; it is a woodland species appearing in coastal redwood forests or, inland, with oaks, madrone, or tanoak. It features a sturdy white stem that sometimes develops grayish to bluish hues, a mealy odor, and spores measuring 7–10 µm across.
First described from Great Britain in the nineteenth century, Entoloma bloxamii has been confusing mycologists ever since: Is it the same as Entoloma madidum (a similar species named from France)? Does it actually occur in North America? Are bloxamii-like collections from the southeastern United States the same as West-Coast collections? How did I get here? How do I work this? Where is that large automobile? This is not my beautiful house!
Ecology: Saprobic; growing alone, scattered, or gregariously in coast redwood forests, or under madrone, tanoak, or oak; distributed along the West Coast; fall and winter. The illustrated and described collections are from California.
Cap: 5–10 cm across; convex or broadly conical, becoming broadly convex, broadly bell-shaped, or nearly flat; sticky when fresh; bald or nearly so; bluish gray to purplish gray or nearly black.
Stem: 5–7 x 1–2 cm; equal above a slightly tapered base; solid and firm; silky or nearly bald; whitish, sometimes tinged with grayish to purplish hues.
Flesh: Thick; white, unchanging when sliced.
Odor and Taste: Mealy.
Spore Print: Pink.
Microscopic Features: Spores 7–10 x 6–9 µm; isodiametric, with shallow angles; 5- or 6-sided; smooth; hyaline in KOH. Lamellar trama parallel. Basidia 4-sterigmate. Hymenial cystidia not found. Pileipellis an ixocutis; elements 2–6 µm wide, smooth, hyaline in KOH; with abundant clamp connections.
