POUL LARSEN
Pileus 1—2 cm broad, convex, often with undulate-dentate margin,
hygrophanous, tawny when moist (k 5), when dry more yellow (1 5),
cuticle even, covered with short yellow fibres. Flesh saffron-yellow or rusty
red, very thin, taste bitter. Stipe cylindrical or slightly expanded below,
pierced by a slender canal above, 2 cm long, 1.5—2.5 mm thick, the lower
two-thirds covered with a fibrous torn, tawny sheath, ending in a raised
very conspicuous ring, above which the stipe is shining, smooth and
purple violet (o 2 to o 3). — Gills rather broad, plane, emarginate-adnate,
rather thick and distant, at first pale purple (n 8), then cinnamon.
Basidia obtusely clavate, 6—7 /x broad, 4-spored. — Spores cinnamon-
coloured, ellipsoidal, punctate, 1-guttulate, 8—9X5—b.2/x, some few spores
up to 10X5.2/u. Caps breaking out in clusters or gregarious.
Distinguished by the clothing of the pileus, colour of the stem and
the small size of the pileus.

Pileus 3—5 cm broad, convex, gibbous, hygrophanous, dark brown
(between g 8 and f 6), covered with white hair-like scales especially along
the margin, veil strongly developed and pendent from the margin. Stipe
3—7 cm long, 4—5 mm thick, cylindrical, hollow. internally brown, exter-

Pileus 1.5—3 cm broad, at first conical, then expanded with verruci-
form centre, hygrophanous, at first dark violet, then reddish grey (k 4),
the centre long remaining dark, cuticle covered with a white fibrillose
layer, dense and fimbrillate along the margin. — Stipe cylindrical,
flexuose, stuffed, 4—7 cm high, 3—4 mm thick, at first all violet, then
only violet at apex, constantly covered with an often zone-like, fibrillose
white layer. — Gills rather distant, emarginate-adnate, at first violet, then
