Form monstrosa Cromb. in Grevillea xix. p. 57 (1891) & 
Monogr. i. p. 474.—Thallus of small scattered round areole, 
somewhat convex and entire at the margins, white. Apothecia 
minute, undeveloped.—L. calearea var. monstrosa Lamy in Bull. 
Soc. Bot. Fr. xxx. p. 392 (1883). 
A very neat form, of small button-like white areole on a dark back- 
ground of gelatinous alg, etc. A central dark dot marks the position 
of the apothecia. Crombie has suggested that it may be only a young 
condition. 
Hab. On calcareous stones of a wall.—B. M. Glen Fender, Blair 
Athole, Perthshire (the only British locality). 
Var. Hoffmanni Sommerf. Suppl. Fl. Lapp. p. 102 (1826).— 
Thallus rather thick of squamule-like contiguous warts, or 
thinnish and cracked-areolate, whitish- or cinerous-grey. Apo- 
thecia generally prominent, the margin often crenulate ; spores 
21-34 p long, 16-20 » thick.—Cromb. Lich. Brit. p. 54 (excl.

the form of the thalline warts.
