Identification Notes:

Cap: 3.5-10 cm wide, rounded-conic when young, becoming broadly convex to nearly plane at maturity; surface moist to tacky, densely matted-fibrillose to squamulose at the center, becoming glabrous or with scattered minute squamules toward the margin, occasionally virgate in places, often rugulose when mature; dark slate-gray overall when young, becoming medium dark gray with a lighter gray margin, finally dingy brownish gray; margin decurved to straight, frequently wavy occasionally lobed. Flesh; white to very light gray; odor and taste strongly farinaceous. Gills: deeply adnexed at first, becoming sinuate at maturity, close to subdistant; white or occasionally light gray, sometimes discoloring blackish on the edges; entire or often eroded. Stalk: 7.5 cm long, 1-3 cm thick, equal to slightly cavate, often twisted or best, with a rounded or abruptly tapered base, solid or hollow; surface silky-fibrillose; white, often with blackish squamules over the upper half or near the apex, not discoloring when handled, becoming dingy buff in age.
