Very beautiful. Saucers , the edges silvery white. Relhan. Saucers very 
numerous, bright brownish colour, the margins scolloped, white, shining, 
the younger flat, the older irregular and deformed, in age black. Mr. 
Woodward. Flat, expanded, rather thick; roundish when young, oblong 
when old, rather concave, smooth, brick colour, paler when dry. Iledwig.

on heaths, dry pastures, and barren places. Gogmagog Hills, Newmarket 
Heath, in Surrey, and Scotland. P. Jan.—Dec.

changing to tubercles, and becoming more yellow ; crust whitish, 
leaf-like, lobed, scolloped, and tiled at the edge.

Crust pure white, shining, divided into lobes so as to appear of the leafy 
kind, expanding into flat circular turfs. Saucers small, concave, at first 
of the same colour with the crust. Linn, the son, from Weber. Crust 
leafy. Saucers, at length becoming convex tubercles. Weber 192. Saucers 
the younger very small. Relh. Leaves cream-coloured, closely tiled. 
Saucers tawny. Mr. Woodward. 
(White Ground Lichen. Lecanora lerdigera. Achar. E.) Heaths and 
dry pastures. Gogmagog Hills, Newmarket, and a heath near New¬ 
market. Sometimes on stone walls. P. Jan.—Dec.

Crust spreading wide, often to a hand’s breadth, moderately thick, yellow. 
Leaves wrinkled, cloven, firmly fixed, lobes blunt, pulpy, with age uniting, 
and becoming powdery. Saucers very numerous, yellow to orange, greenish 
when wet. Hoffman. Fructifications when young slightly concave, or 
flat, of an orange yellow, bordered with a paler lemon yellow, the colour 
of the crust. When older the fructifications swell into the form of tuber¬ 
cles, the border disappears, and the crust changes to brown yellow. L. 
Jlavicans seems to be only a variety of this. Mr. Griffith, whose exten¬ 
sive knowledge of this genus, aided by long continued observation, 
stamps a high authority upon his opinions, tells me he has observed 
that the Lichens with farinaceous crusts become foliaceous, and that pro¬ 
bably L. candelarius, concolor, parietinus, and Jlavicans may be all the 
same plant under different circumstances.
