Description:Basidiomata hypogeous to partially
emergent or sometimes exposed in animal digs, solitary
or in scattered, gregarious groups. Basidiomata globose
to subglobose, flattened, or irregular, (5–) –25 (–30) x
(5–) –20 (–25) mm, in youth with a suprapellis turf of
scarlet, tapered cystidia that fade when dried and a
pellis mixture of pale yellow and scarlet areas that often
separate into patches, with age the colors darkening
to darker dull red and the turf fading and collapsing in
patches, at senescence becoming dark reddish-brown
with the suprapellis turf largely to entirely collapsed
(Image 1a). Stipe absent or rarely present as a less than
2mm long, readily detaching stub at base of fruiting
body, its surface concolorous with peridiopellis. Gleba
loculate, in youth, the trama white to ivory or pale
yellow, with age developing to brownish yellow with
brown zones and brown tissue around worm holes, and
at senescence brown overall (Image 1a & c); spores in
mass in the locules white, often brownish where glebal
tissue has stained brown. Odor in youth mild, later often
faintly pleasant, at senescence somewhat unpleasant.
Peridium 115–180 μm thick, beset with a crowded
to dispersed, scarlet pubescence. Peridiopellis 25–90
μm thick, scarlet in fresh mounts of young specimens
and often with scattered red granular deposits near the
surface, later darkening to brown or reddish-brown and
paler towards gleba, the hyphae compact and tightly
entangled, 4–8 μm broad, the suprapellis a pubescence
of tapered, tangled, cystidia 20–40 μm tall, scarlet when
fresh and sometimes with scattered scarlet deposits at
the base but fading slowly after exposure, in microscope
mounts of KOH quickly becoming hyaline (Image 1d).
Subpellis averaging 90μm thick with loosely interwoven
hyphae 3–8 μm thick. Gleba with a subhymenium up
to 30μm thick, composed of irregularly shaped, inflated
cells up to 11μm broad. Hymenophoral trama up to 18–
31 μm thick, composed of tightly intertwined hyphae,
3–7 μm broad with occasional cells in trama inflated
up to 18μm. Hymenophoral cystidia 39–42 x 8–11 μm,
scattered, hyaline smooth, cylindrical to narrowly clavate
with obtuse apices, walls less than 1μm thick (Image
1f). Basidia 41–48 x 9–11 μm, clavate, tapering near
the base, smooth, less than 1μm thick, 2 and 4 spored,
sterigmata 4–6 x 1–2 μm. Spores 7–8 x 7–9 μm, globose
to subglobose with sterigmal attachment no more than
1μm long tapering towards the tip, spore wall less than
0.5μm thick, becoming slightly thicker near sterigmal
attachment. Spore ornamentation less than 1μm tall,
weakly amyloid, ranging from irregular granules to a
well-developed reticulum (Image 1e).
