Description: Pileus 5-15 mm diam., hemispherical or conical
when young, becoming pulvinate, margin strongly incurved and connected with
stipe-columella; yellow brown with distinct reddish or orange tinge; smooth,
slightly viscid, non striate; margin conspicuously covered with orange or reddish
coloured veil remnants. Gleba cellular, cells about 1-2 mm diam., not distinctly
radially arranged; brownish, without well differentiated tramal plates, not
gelatinised. Stipe 6-20 x 3-4 mm, cylindrical or fusoid, attenuated towards
the apex (columella), normally transcurrent and extending to the cortex of the
cuticle but rarely terminating abruptly in the gleba; yellow, ornamented with
distinct, adpressed, orange or reddish coloured zones forming one or more girdles
of the veil; when wet slightly viscid, becoming dry with age. fistulose. Context
whitish, under the cortex of the pileus yellow-brown, up to 2 mm diam. Chemical
reactions on pileus: KOH—brown. Smell and taste not distinctive.
Spores 13.5-16 x 8-10 µm, elliptical, sometimes
even naviculate, smooth, brownish yellow, with distinct germ pore, membrane
up to 1µm diam., axially symmetrical. Basidia 23-31 x 7-9 µm., 4-spored. Chrysocystidia
30-40 x 8-10 µm, fusoid, with short terminal projections, coloured by yellow
plasmatic pigment, membrane hyaline and thin-walled. Cuticle a cutis consisting
of cylindrical, repent hyphae (3-10 µm), membrane gelatinised, encrusted by
yellowish pigment, clamp connections present.
Habitat: On rotten wood. New Zealand.
