Hoot-leaves minute, and, like the whole of the plant, of a glossy jelly-like 
appearance, resembling aTremella. Tubercles in clusters, large in pro¬ 
portion to the leaf, numerous, mostly on fruit stalks, lopped at the end, 
surrounded with a blunt border. Linn. Observable in October and 
November, forming roundish raised substances, with numerous tubercles 
rising from fleshy leaves interlaced and connected. Leaves examined 
separately, pellucid, dirty green, not one quarter of an inch long. Tu¬ 
bercles at first small, convex, the colour of the leaves: when larger, flat, 
or a little hollowed. Dill.

Dillenius remarks that it exists at all seasons of the year, but dries up like 
a Tremella, so as only to be found in wet weather. 
L. cris'pus. Saucers blackish green, changing to red brown; scol¬ 
loped : leaves tiled, lobed, lopped, scolloped. 
Dill. 19. 23— Jacq. Coll. iii. 10. 1— (E. Bot. 834. E.) 
Distinguishable from L. cristatus by its being more curled and less jelly- 
like, the lobes of the leaves being round, blunt, and not divided as in 
L. cristatus. Mr. Woodward. Leaves dark green, rather thick, divided 
into broad shallow lobes, innermost leaves smallest, curled. Lobes blunt, 
scolloped in the summer, hardly perceptibly so in the spring. Saucers 
dark green, lying flat on the leaves ; border granulated. Dill. 
(Crisped Lichen. E.) Shady places on stones and at the bottom of walls. 
L. rupes^tris. Tubercles blackish-green, roundish: foliage dark 
green, gelatinous; lobes oblong, thick, blunt. 
Dill 19.22. 
Gelatinous, dark green, somewhat transparent, prostrate, wide spreading, 
rather slippery, without roots, but adhering to the soil. Tubercles 
roundish, gelatinous, dark green. Blackish and shrinking when dry, so 
as hardly to be found, but swelling again when wet. Jacquin. Gelatinous, 
brown green: rigid. Segments lobed, blunt, oblong, thick, surface not 
w'rinkled. Tubercles rare, dull brown green, globular or flat; in the 
, extremities, or on the disc. Dill.
