Fruit bodies are characterized by the small dark brown to black conical scales covering the cap, and the net-like pattern of ridges on the upper stem.

[3] The specific epithet foveatus is derived from the Latin adjective foveola, referring to a surface with pits or depressions.

The pores on the underside of the cap are between 0.5 and 1 mm wide, dirty white then gray, and they bruise a brownish-black color.

The hyphae that make up the cap surface and the warts are branched, loosely interwoven, and sooty colored; the unclamped cells typically measure 17–45 by 9–26 μm.
