M. vulgaris ( vulgaris , common). Plate X. 12. 
P. in., almost membranaceous, depressed at maturity, 
with a minute papillate umbo, viscid, pale brown or greyish, 
marked with dark lines. G. slightly decurrent, rather broad, 
white. S. f-ij in., slender, viscid, tough, pale. Common 
amongst pine-leaves and twigs. 
M. pelliculosa (from the thin, separable pellicle of the 
pileus), frequent amongst heather and in heathy fir woods; 
is larger than the above (P. up to 1 in.) ; also differs in the 
viscid, separable cuticle. 
M. epipterygia (from its frequent occurrence on bracken 
stalks— Ptevis aquilina) —P. in., S. 2-4 in.—is a yellowish- 
green species, common on branches and twigs in damp 
places. The pileus and stem are covered with a viscid,

umbo. G. adnexed, white or faintly green. 5 . 2-3 in., 
slender, rather fragile, greyish-black, base downy and root¬

M. haematopa (Gr. haima , blood; pous, a foot—from the 
blood-red juice of the stem), appearing in tufts on trunks 
and stumps in aut., may be easily known by the minutely 
toothed margin of the pileus (J-i in.) and the entire white 
gills. It gives out a dark-red juice when broken.
