Brief Description:

From Ponce. (1968) (public domain):

Unexpanded basidiocarp ovate with a point up to 4 mm. long, or with a
rounded umbo, half-exposed or superficial, 2-3 cm. wide, 3 cm. high,
with the mycelium attached to a basal point, becoming expanded when 3
cm. wide; exoperidium split to about the middle into 5-9 pliable,
thin, expanded or revolute, equal, acute rays, leaving the base
saccate; when open, the rays can attain a width of 1-2 cm.; fleshy
layer brown, adnate, frequently rimose; outer layer ochraceous buff or
cinnamon buff, spongy-felted, with very little adhering debris; when
dried, irregularly rimose or pulling off over considerable areas; with
a prominent umbilical scar in the middle of the base where the
mycelium was attached; endoperidium sessile, 0.5-2 cm. in diameter,
globose, glabrous, brown, partially enclosed by the saccate base of
the exoperidium; peristome conic, fibrillose, delimited by a circular,
raised or depressed line, silky, paler or more brownish than the
spore-case wall; gleba umber or paler; columella indistinct, or a
pseudocolumella present; spores globose, 3.4um in diameter, globose,
verrucose, with hyaline or yellowish warts (there are many
poorly-formed spores in mounts); capillitium 4um, pale yellowish to
brownish, very thick-walled, tapering, undulate, often cracked, some
threads having ramifications at the ends, 4um diameter, incrusted with
much debris.
