New Zealand “hirsutum‑like” earth tongues represent a species complex, and several lineages may be present.

Fruitbody: Slender, dark brown-black to black, club‑ to tongue‑shaped, typically 25–80 mm tall. Fertile head velvety, roughened, distinctly setose, usually 10-25 mm long, cylindrical to narrowly clavate, apex rounded.
Setae: Abundant dark brown to black, thick‑walled hairs embedded in the hymenium and often extending down the stipe. Setae are straight, stiff, bristle‑like, visible with a hand lens.
Stipe: black, smooth to finely hairy, 1.5-3 mm thick, continuous with the fertile head, sometimes slightly twisted.
Flesh: Dark brown‑black, tough‑fleshy.
