Description
The cap is 1.5–4 centimetres (1⁄2–1+1⁄2 in) across, dry, at first hemispheric, expanding to campanulate or convex, [1] with an incurved margin when young. Young caps start out light brown and fade to off-white or light gray at maturity, sometimes with yellowish or brownish tones. Often developing cracks in dry weather, slightly hygrophanous, turning greenish or blue where damaged. [1]
The gills are broadly adnate to adnexed, [1] close, starting out gray and turning black as the spores mature. The gill faces have a mottled appearance and the edges are white. The spore print is black. [1]
The stipe is 6–12 cm long by 2 to 4 mm thick, equal to slightly enlarged at the base, [1] pruinose, colored like the cap, staining somewhat blue where bruised.
The taste and odor are farinaceous.
Microscopic features
The spores are jet black, 12–15 x 7–11 μm, smooth, opaque, elliptical. With a germ pore.
Basidia 4 spored, pleurocystidia fusoid-ventricose, cheilocystidia 12 x 4 μm.
