Scattered to gregarious or
subfasiculate. Growing in a wide variety of habitats, e.g.
burnt heaths, naked peat, Sphagnum bogs, boggy
ground under conifers. Summer to autumn. Occasional but widely distributed. See the records in The Norwegian Mycological Database.
mm across, conical campanulate with a more or less prominent
umbo, flattening with age, and often radiately wrinkled,
not or little translucent-striate, pruinose, glabrescent,
dark sepia brown to almost black when young, pallescent
with age, becoming dark grey-brown to dingy brownish, margin
incurved, then spreading, sinuate, becoming scalloped, dingy
brownish to pallid. Flesh cartilaginous-tough.
Odour mostly indistincive, but
also experienced as raphanoid or farinaceous. Lamellae
18-34 reaching the stipe, elastic-tough, ascending, adnate
to almost emarginate, decurrent with a tooth, smooth to
strongly veined and anastmosing, fairly dark grey-brown,
fading with age to pale greyish or whitish, the edge paler.
Stipe 30-130 x 2-4 mm, hollow,
cartilaginous-tough, smooth to longitudinally finely rugulose
or becoming fissured, pruinose, glabrescent for the greater
part, lubricous when wet, pallid to whitish above, paler
or darker sepia brown below, the base densely covered with
long, coarse, flexuous, whitish fibrils and gradually passing
into a shorter or longer root.
30-50 x 10-15 μm, clavate, 2-spored and clampless or 4-spored with clamps, with sterigmata up to 10 μm long. Spores
11.6-17.5 x 7.6-8.4 μm (2-spored basidia) or 9-12.5
x 6-8.1 μm (4-spored basidia), Qav ~ 1.3-2.0, pip-shaped, smooth, amyloid.
Cheilocystidia 24-72 x 5.5-17 μm, forming a sterile band, clavate, subcylindrical
or irregularly shaped, covered with few to numerous, fairly
coarse excrescences. Pleurocystidia absent. Lamellar trama dextrinoid. Hyphae of the pileipellis
2-3.5 μm wide, covered with warts or short excrescences. Hyphae
of the cortical layer of the stipe 3-4.5 μm wide, diverticulate, excrescences 2-5.5 x 1-2 μm.

Mycena magaspora has occured in the
literature by several different names ( as M. uracea,
M. permixta and M. dissimulabilis). It
belongs to sect. Mycena,
and can be separated from the other members of the section
on account of the dark colour of the pileus, the diverticulate
hyphae of the pileipellis, the broad spores, and the occurence
on peat, in burnt heaths, among Sphagnum etc., not on decayed
wood. A typical character is the cartilaginous-tough stipe,
which often is somewhat rugulose, reminding of M.
