Local name: No local name known

Edibility: Unknown

Habitat: Terrestrial amongst leaf litters and scattered to gregarious.

Description: Fruiting bodies:  1-3 cm, loosely lobed, often forming two or three distinct lobes, smooth or somewhat wrinkled, dark brownish grey to black, the margin not typically rolled upwards. Under surface: Very finely fuzzy, greyish to greyish brown. Stem: 1-5 cm tall, up to 0.5 cm thick, dark grey or greyish brown, finely fuzzy.  Flesh: Thin and brittle.

Comments: This species can be identified by its greyish-brown to brown mottled cap and deeply ribbed stalk. It is reminiscent of H crispa and H. lacunosa, but is darker than the former and paler than the latter. It might also be confused with Gyromitra californica, but is less fragile and lacks the strongly spreading or umbrella-like cap of that species. H.fusa is said to be quite similar, but has distinct ribs on the underside of the cap and lacks a flaring margin.
