Species typical of meadows or roadsides at woodland edges, with a pileus up to 10 cm across, convex with an obtuse central umbo, dark reddish-brown, a stipe thickened at the base with a brownish-grey, finely scaly surface, a fungal odour, and a sweet, farinaceous taste.

Cuticle (pileipellis) formed by filamentous, irregularly interwoven hyphae 4–8 µm wide, with abundant brown intracellular pigment, septate, with simple septa (clampless).

Cheilocystidia fusiform to lageniform, ventricose, moderately thick-walled, measuring 50–70 µm long by 10–14 µm wide, and generally with apical crystal encrustations.

Lamellar trama regular to parallel.

Basidia clavate, 30–35 µm long by 7–9 µm wide, with a simple base, 4-spored.

Spores ellipsoidal, hyaline, with a verrucose wall, measuring 6.5–8.8 µm long by 4.3–5.5 µm wide, with a minute hyaline apiculus at one end, containing oil droplets (guttules) inside, amyloid in Melzer's reagent.
