Cap: Umbro-brown, usually darker in the middle, initially conically bell-shaped, later spread flat, in the middle with a noticeable tubercle, naked in young mushrooms, later slightly fibrous and radially cracked, 30-60 mm in diameter. The plates are whitish at first, later white-grayish, light-brown to maturity, 4-6 mm wide, frequent, first adherent at the stem, later almost free.

Stem: Cylindrical, slightly refined from above, tuber-like thickened at the base, solid, 50-80 mm in height and 4-8 mm in thickness, slightly longitudinally fibrous, monochromatic with a cap, only slightly lighter.

Flesh: White or light creamy, slightly brown in the stem (except for the tuberous base). The taste and smell are inexpressive.

Spore powder: Light ocher-brown.

Spores: 9-10 x 5-6 microns, ovate, unevenly tuberous surface (5-6 tubercles), light buffy.

Growth: Grows on soil from August to late October in deciduous forests. Fruit bodies appear singly or in small groups in damp grassy places, most often under birches.
