— Cystidia at the edge of gills flask-shaped, with a short, thin stalk
below, neck 10 X 4—5 /t, head 5—6 /í in diameter.
Note. Cannot be referred to any species described in the literature,
but as the treatment of the Galera species by the different anthors is
very uncertain and dissimilar, it is difflcult to give any grounds for the
establishment of a new species in this genus.

This species is very common and occurs among moss and grass in
bogs, swamps, and wet tuffs [P. L.].
Pileus 1—2 cm broad, heinispherical, then expanded but always with
a raised centre, skin-like, with thin flesh, hygroplianous, pellucidly striate,
when moist, the colour is e 3, in the dry state b 7, the margin in young
specimens has a pendent white fibrillose veil. — Stipe subconical, 1—2 mm
thick above, 2—3 mm below, 4—6 cm long, covered with a silky white
coating, below which it is coloured like the cap. — Gills distant, adnate.
Edge of gills rather thick and somewhat fimbriflate. Colour of giffs b 6.
— Spores ellipsoidal, smooth, yellow, germ pore absent, length very
variable, viz. 10—15X6—7 ju. Cystidia at edge of gills rather variable
in shape, but mostly elongate-flaskshaped with a swollen apex, 45—50 /t
long, the greatest breadth near the base being c. 10 /t, the head up to
8 /t in diameter.
Crepidotus Fries.

On the island of Slutnes in
Mývatn [P. L.]. — Grows on dead
branches of Salix phylicifolia lying
on damp ground.
Pileus 5—8 mm broad, resu-
pinate, excentrically attached by
the upper side of the pileus, citron-

hairs on the raised and somewhat
incurved margin. — Gills crowded,
