On fallen twigs, leaves, coniferous needles,
dead culms of grasses. Summer to autumn.
M. stylobates is fairly common, but
there are not many records in O. Collected north to Nord-Trøndelag. See the records
in The Norwegian Mycological Database.
Pileus up to 10
mm across, viscid, covered with a separable, gelatinous
pellicle, conical to planoconvex, flattening with age, translucent-striate,
sulcate, glabrous or occasionally somewhat hispid, pale grey-brown to greyish white. Lamellae
14 - 18 reaching the stipe, ascending, free, often with
a pseudocollarium, white. Stipe
up to 35 x 0.7 mm, fragile, straight, pruinose above, glabrous
farther below, watery grey to white, springing from a basal disc which
is up to 2 mm across, sulcate, pubescent, white, with a
ciliate margin. Odour none.
Basidia 17.5-23 x 6-7 μm, clavate,
4-spored. Spores 7.0-11.0 x 3.5-5.5 μm, pip-shaped,
smooth, amyloid. Cheilocystidia
20-60 x 3.5-11.5 μm, irregularly clavate, fusiform
or almost cylindrical, with few to numerous variously shaped,
and often coarse excrescences with rounded apices. Pleurocystidia
absent. Lamellar trama dextrinoid. Hyphae of the pileipellis
2.5-6 μm wide, variously branched, smooth or densely covered with warts or short cylindrical excrescences 1-3 x 1 μm. Hyphae
of the cortical layer of the stipe ca 2 μm wide, smooth
with caulocystidia
45-80 x 7-8 μm, fusiform, smooth. Clamp connections present.
In Norway there are several species with a
basal disc. Mycena mucor
(Batsch) Quél. is quite similar to M. stylobates.
It is usually smaller and grows on fallen, decaying leaves
of Quercus. The
cheilocystidia are different, with very slender excrescences,
and the margin of the basal disc is not ciliate. M.
bulbosa (Cejp) Kühner. grows on herbaceous
stalks in wet habitats, the spores are non-amyloid, and
the lamellar edge contains a tough-elastic, gelatinous thread.
M. aciculata (A. H.
Sm.) Desjardin & E. Horak has a pubescent to setose
pileus (showing as long, thick-walled
cells in the microscope), and an entirely puberulous
stipe springing from a setose basal disc; the
cheilocystidia are different, and the spores are non-amyloid.
