Bears the same relation to the species as var. contzceoides does to 
L. farinaria. Both may be only growth forms. The apothecia are 
generally numerous and crowded, in some places obscuring the thallus. 
Thallus and apothecial margins are firmer than in the species.

Thallus as in the species. ‘ Apothecia bright emerald-green.”

Exsicc. Larb. Lich. Hb. (without a number). 
The apothecia on our solitary specimen are now very dark, and 
the epithecium in section is a layer of brown granules; the paraphyses 
are stout, uneven and branched, the spores measure about 12 » long 
and 4 thick. It is reported from W. France on oak wood, and is 
recorded from Lamlash, Arran, by Wheldon and Travis in Journ. Bot. 
li. p. 251 (1913). ; 
Hab. On a decorticated stump of oak.—B. M. Chiltern Hills, 
Oxfordshire. 
Subsp. inversa Nyl. in Flora Ixii. p. 361 (1879).—Thallus 
nearly as in the species. Apothecia with a more prominent, sub- 
entire margin ; spores not seen.—Cromb. ll. ec. 
There is only one specimen in our herbarium, originally labelled 
Lecanora albo-flavida Tayl. It is too scanty for examination. 
Nylander thinks that if the spores were known it might be a new 
species. The reactions agree with those of L. expallens. 
Hab. On branches of furze.—B. M. Finnechy River, Kerry.
