Form 1. styracella Nyl. Lich. Scand. (1861) p. 62.—Thallus 
foliolose at the base, the leaflets minute, thin, lobed, subimbricate 
or somewhat scattered; podetia simple, slender, subuliform, white- 
pulverulent, the seyphi very minute with entire margin. Apothecia 
not seen rightly developed.cCromb. Grevillea, xi. p. 114.—Beo-

Differs chiefly in the thinly lobed basal folioles and in the simj] r 
podetia, which are attenuate upwards. The minute scyphi are rarely 
present, and the apothecia occur only in a young state. 
Hab. On mossy trunks of old trees in mountainous districts.— Distr. 
Local and rare in S., W., and N. England, more frequent among the 
Scottish Grampians; rare in the Channel Islands and in S.W. Ireland —

This form is as it were only a more turgid state of the preceding, with 
which also it agrees in the length of the clavato-ventricose podetia 
(though these are sometimes thick and stunted), which render it easily 
distinguished. It is apparently everywhere extremely rare with rightly 
developed apothecia. 
Hab. On the ground among mosses on heaths and on the dead stumps 
of trees in wooded upland districts —Distr. Found only in 8., W.,and N. 
England, N. Wales, and among the Grampians, Scotland—B. M.: New
