Var. scabrosa Cromb. in Grevillea xii. p. 92 (1884) (incl. f. 
incrassata) & Monogr. i. 169 (incl. f. intwmescens)—Primary 
thallus of crowded granular squamules, greyish or glaucous, 
white beneath; podetia short or medium-sized, simple or 
variously divided, ascyphous, but blunt at the tips, covered with 
minute squamules or rough with granules. Apothecia small, 
. sometimes confluent.—Form scabrosa Cromb. in Grevillea xi. 
p. 115 (1883) ; var. scabrosa f. intumeseens Cromb. in Grevillea 
v. p. 46 (1886). Cladonia coccifera var. macilenta £. scabrosa 
Mudd Brit. Clad. p. 32 (1865). 
Exsicc. Johns. nos. 181 and 298; Mudd Clad. n. 73. 
Somewhat similar to f. scolecina in the slighter forms, and 
gradually approaching to the more squamulose stouter condition 
(f£. entumescens). 
Hab. On decaying stumps and on turf-walls in wooded districts.— 
Distr. Local and scarce in S.W. and N. England, N. Wales and 
Treland, frequent among the Scottish Grampians.—B. M. Near

Var. ostreata Nyl. Syn. Lich. i. p. 225 (1860).—Primary 
squamules crowded, ascending or subimbricate, usually rather 
sorediose on the margins and under surface; podetia short, 
stoutish, densely sorediose, obtuse at the apices. Apothecia 
minute, very rare.—Cromb. in Grevillea®xi. p. 115 (1883) & 
Monogr. i. p. 17. Cladonia digitata subsp. macilenta f. ostreati- 
formis Leight. Lich. Fl. p. 70 (1871) ; ed. 3, p. 64. 
Exsiec. Leight. n. 371. 
The basal squamules are somewhat like those of Lecidia ostreata, 
but larger, and with a different reaction with potash. Leighton has 
suggested that Lichen rubiformis Sm. Engl. Bot. t. 2112 (1810) 
might be the same as this variety, but though the squamules bear 
some resemblance, the red ‘ fruits’’ are rather those of some parasitic 
fungus. Hooker refers to it doubtfully as Psora? rubiformis (Sm. 
Engl. Fl. v. p. 193), and Mudd has recorded it as Cladonia coccifera 
var. macilenta f. rubiformis (Man. p. 62). : 
Hab. On old mossy stumps of trees.—Distr. Found sparingly here 
and there throughout England.—B. M. New Forest, Hants; Epping 
Forest, Essex ; Wrekin Hill, Shropshire.

v. p. 179 (1866).—Basal squamules rather small, crenate or
