456 CYCLOCARPINE © [ CLADONIA 
Distinguished by the yellow colour of the under side of the basal 
squamules which takes on a*deep orange tint on the application of 
potash if followed by calcium chloride. 
Hab. On old mosses in high altitudes.—. M. Graygarth Fell, 
Lancashire (without podetia). . 
34. C. digitata Hoffm. Deutschl. Fl. ii. p. 124 (1795)? Scheer. 
p. 22 (1823).—Primary squamules rather large, roundly lobed or 
crenate, pale-green above, beneath usually whitish and pulveru- 
lent ; podetia subcylindrical, rarely branched, unequally corticate 
at the base, white or yellow, pulverulent above, scyphiferous, 
the scyphi rather narrow with the margin incurved, irregularly 
divided and proliferous (K + yellow, CaCl—). Apothecia 
small and scattered or confluent; spores 9-11 p long, 3°5-4 pw 
thick.—Cromb. Lich. Brit. p. 21 & Monogr. i. p. 166 (inel.

Somewhat like C. deformis, but sufficiently distinguished by the 
digitate branching, the more slender podetia (except in f. monstrosa), 
the incurved scyphi, and the pronounced yellow reaction with potash. 
In f. brachytes the podetia are slender with the basal squamules well 
developed. : 
Hab. On decaying trunks of trees among mosses in somewhat 
upland districts.—Dzstr. Local and rather scarce in the more hilly
