Resembles L. vernalis, but differs in the more developed thallus 

 and the characters given of the apothecia. These are at times con- 

 glomerate and difform. 



Hah. On the ground in alpine situations. — Distr. Very local and 

 scarce. — B. M. Ben Lawers, Perthshire ; Ben Avon, Braemar, 

 Aberdeenshire.

 Thallus effuse, thickish, granulose, continuous or diffract-rimose, 

 the granules small, whitish or greenish-grey (K — , CaCl — ), 

 Apothecia submoderate, adnate, at first plane with thin, darker 

 margin, at length convex, immarginate and somewhat difform, 

 brownish-black ; hypothecium dark ; paraphyses colourless, in- 

 crassate and dark at the apices ; spores oblong or ovoid, 0,010-18

 iodine. — Cromb. in Grevillea xxii. p. 10 ; Leight. Lich. Fl. ed. 3, 

 p. 273. L. cuprea subsp. Berengeriana Cromb. Lich. Brit. p. 69

 Berengeriana Massal. Ric. Lich. p. 128, £. 254 (1852). 



Closely related to the preceding, differing chiefly in the colour of the 

 apothecia, the character of the paraphyses and the form of the spores. 



Hah. On the ground at high altitudes in mountainous districts, 

 very rare. — B. M. Ben Lawers and Mael Graedha, Perthshire ; Ben- 

 naboord, Braemar, Aberdeenshire. 



Var. p lecanodes Nyl. ex Cromb. in Grevillea xxii. p. 10

 in Journ. Bot. xx. p. 275 (1882). 



Well characterized by the spuriously lecanoroid apothecia. The 

 other characters are entirely as in the following, though the para- 

 physes are occasionally nearly simple. 



Hah. Incrusting decayed mosses on the ground. — B, M. Near the 

 summit of Ben Lawers, Perthshire (the only locality).
