HYMENOMYCETES 
ground. The var. swavtzii is a firmer plant, differing in the 
almost plane, whitish pileus, with dark disc and whitish stem, 
with the apex tinged with violet. 
CLITOCYBE 
(Gr. klitos, a declivity ; kube, a head—from the 
decurrent gills) 
GROUP I.—PILEUS FLESHY, PALE AND MINUTELY SILKY 
WHEN DRY. FLESH FIRM | NOT HYGROPHANOUS 
C. nebularis (nebula, a cloud; the greyish pileus being 
frequently clouded with white mycelium), “ Cheese-cap.” 
P. 2-5 in., convex, then plane, often gibbous when young. 
Smoky-brown, becoming livid or grey ; sometimes pruin- 
ose. F. white, thick at the disc, thinner at the margin. 
G. slightly decurrent, arcuate, crowded; greyish-white. 
5 . 2-3 in., stout, a little attenuated upwards, fibrillosely 
seriate, firm, stuffed; dingy - white. Smells like curd 
cheese. Common in aut. amongst dead leaves in woods. 
The white mycelium on the pileus gives rise (rarely) to 
Volvaria Loveiana (see Plate XI. 7). 
C. clavipes ( clava , a club—from the shape of the stem) is 
the colour of the preceding, but only half the size. G. 
deeply decurrent. S. dark, solid, markedly attenuated 
upwards. Common in pine-woods. 
C. phyllophila (Gr. phullon , a leaf; philos, loving) is wholly 
whitish tan. 
P. 1-3 in. S. 2-3 in. A somewhat caespitose, tough 
species common amongst leaves (especially beech) in aut. 
C. pithyophila (Gr. pitus, pine ; philos, loving) is a wholly 
white species, frequent in pine-woods. “ Gregarious or 
slightly caespitose. Allied to C.phyllophila, but distinguished 
by the persistently white gills and white pileus. Smell 
pleasant. C. tuba closely resembles the present species, 
but differs in the deeply decurrent gills ” (Massee).
