[1] The fruit bodies of Lepiota babruka have caps up to 3 cm (1.2 in) wide, which are initially broadly convex before flattening out in age, usually developing a shallow umbo.

They are crowded together, and have 3–4 tiers of lamellulae (short gills that do not extend completely from the cap margin to the stem).

Its color is initially brown before darkening, and the surface is fibrillose (made of thin, threadlike fibers).

A whitish, membranous ring is present on the upper portion of the stem in young fruit bodies, but it does not last for long.

[1] The fruit bodies of Lepiota babruka grow singly on the ground among decaying leaf litter.
