Pileus 15 - 28 mm
across, conical to campnulate, umbonate, finally convex,
translucent-striate, subtomentose, matted when dried, pale
greyish brown, darker at the centre, becoming spotted with
vinaceous brown stains. Flesh c. 1 mm broad, pallid. Odour
absent. Lamellae c. 22 reaching the stipe, tender, ascending,
up to 2 mm broad, ventricose, adnate to somewhat sinuate,
whitish with some pinkish tint, becoming spotted with vinaceous
stains, the edge convex, concolorous. Stipe 50 - 80 x 1
- 2 mm, hollow, not fragile, equal, terete, straight to
somewhat curved, apically minutely puberulous, glabrescent
farther below, finely innate-striate, at first watery whitish,
then turning pale greyish brown from base upwards, becoming
spotted with vinaceous red stains, the base covered with
long, coarse, whitish fibrils.
Basidia 27-36 x 7-9 µm, clavate, 4-spored,
clamped, with sterigmata 6.5-7 µm long. Spores 8.8-9.4
x 5.8-6.7 µm, pip-shaped, smooth, weakly amyloid.
Cheilocystidia 30-70 x 5.5-9 x 2-5 µm, fusiform, sublageniform,
subcylindrical, clamped, apically either narrowed into a
slender and frequently torulose neck and moreover smooth
towards the middle of the lamella, or variously and more
or less strongly branched near the margin of the pileus,
with the excrescences 6.5-16 x 1.8-2.5 µm. Pleurocystidia absent. Lamellar trama brownish vinescent in Melzer's reagent.
Hyphae of the pileipellis 2-4.5 µm wide, clamped,
thickly covered with much branched excrescences 2-45 x 1.3-2
µm which form intricately entwined, dense masses.
Hyphae of the cortical layer of the stipe 0.9-2.7 µm
wide, clamped, smooth for the greater part but towards the
apex of the stipe sparsely covered with scattered, detersile,
cylindrical excrescences 4.5-13.5 x 0.9-1.5 µm.
The holotype was growing on a stump of a deciduous
The description is adopted entirely from Maas
Geesteranus (1993: 343-345). The present species possesses
a combination of characters which is unique in sect. Fragilipedes:
vinaceous spots, cheilocystidia with a torulose neck, and
hyphae of the pileipellis whose excrescences form an uncommonly
No other records than the type collection.
This taxon needs to be recollected before a clear opinion
can be given. It could represent a deviating form of M. polygramma.
