FUNGI OF ICELAND 533 
pierced, with a frayed ring like a Telamonia, above the ring yellow (1 4) 
and mealy, below ring of the colour k 2, towards the base sulcate and 
dilated. — Gills broad, emarginate, cinnamon, with yellow frayed edge. 
— Spores brown, smooth, ellipsoidal, the greater part 8—9X5 u, a few 
10—11%X5.5 u and very few 74.5 u. No coronate cystidia, but edge 
of gills densely beset with vesiculously inflated cells, some of which con- 
tain a yellow juice. 
Allied to I. dulcamara, but distinguished by form and colour.

Pileus 4—6 cm broad, at first conical, then expanded with a con- 
spicuous umbo, cuticle radiately fibrillose and rimose except in the centre 
where it is entire and even, colour of margin 12 to k 2, colour of the 
umbo k3 to f8. Flesh nearly white. Stipe cylindrical or somewhat 
attenuated at apex, stuffed, pale, fibrillose-lacerate. Gills rounded towards 
stipe, narrowly adnate or nearly free, greyish yellow, then olivaceous, 
edge of gills dentate-fimbriate at length nearly even. — Spores brown, 
smooth, broadly ellipsoidal or ovate, a few reniform, as a rule 2-guttu- 
late, 11-12 X 6.5—8 u (a very few up to 15 X 7.8 u.) No coronate 
cystidia, but numerous thick-walled, clavate or fusiform cells at the edge 
of the gills.

Pileus 2—4 cm broad, campanulate, somewhat hygrophanous, densely 
covered with squarrose scales, when moist the colour of the pileus is f 6, 
when dry f 8. A similar change takes place 
in the colour of the flesh, which is a 
pale greenish blue when moist (a 8), when 
dry b8. When crushed the flesh colours Q 
red (n 7). — Stipe cylindrical, 2—4 cm high, 
3—4 mm thick, occasionally flexuose, mealy | CN g ()

brown, at base strongly blue-green. — 
Gills broad, deeply emarginate, decurrent Fig. 10.

ovoid, sligthly curved, smooth, brown, 1- to 3-guttulate, 10—16.5%X6—8 u. 
No coronate cystidia, but the edge of gills closely beset with clavate, 
swollen cells.
