Brief Description:

From Ponce. (1968) (public domain):

Unexpanded basidiocarp globose, at first submerged, medium or large
size; exoperidium split to about the middle into 4-5 rays; the outer
layer remaining as a hollow cup in the substratum; the inner fibrous
and fleshy layers becoming strongly fornicate, attached at tips to the
basal cup, rays firm, thick, brown; fleshy layer dark brown and
adherent or partly peeled off, in old plants worn away; base strongly
convex; endoperidium subglobose or urnshaped to depressed, dark brown,
finely velvety on surface, constricted near the base so as to form a
ring-like apophysis above the pedicel; pedicel about 2-3 mm. long;
mouth naked, conical or mammiform, tubular, apex fibrillose or
lacerate; gleba ferruginous; columella long-elliptical, 2-3 mm. high;
spores globose, 5-6um in diameter, umber, verrucose, reticulate;
capillitium threads 10-12um thick, about as dark as the spores; walls
roughened, tapering, with ramifications at the ends.
