FUNGI OF ICELAND 545 
— Cystidia at the edge of gills flask-shaped, with a short, thin stalk 
below, neck 10 X 4—5 u, head 5—6 x 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 difficult to give any grounds for the 
establishment of a new species in this genus.

ochre-brown. — Stipe cylindrical, somewhat undulate, pale, slightly dilated

This species is very common and occurs among moss and grass in 
bogs, swamps, and wet tuffs [P. L.]. 
Pileus 1—2 cm broad, hemispherical, then expanded but always with 
a raised centre, skin-like, with thin flesh, hygrophanous, 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 fimbrillate. Colour of gills b 6. 
— Spores ellipsoidal, smooth, yellow, germ pore absent, length very 
variable, viz. 10—15X6—7 u. Cystidia at edge of gills rather variable 
in shape, but mostly elongate-flaskshaped with a swollen apex, 45—50 u 
long, the greatest breadth near the base being c. 10 u, the head up to 
8 u in diameter.
