CLADONIA. | CLADONIEL, 131 
often also pulverulent at the margins. It is not uncommon in a fertile 
condition, the apothecia being often confluent. 
Hab. Among mosses on the ground and old walls in maritime and 
upland districts—Déstr. General and common in Great Britain, and 
Lacon also in Ireland, though no specimens have been seen ; rare in the 
hannel Islands.—B. M.: Island of Guernsey. Wootton Common, Nor- 
folk; Epping Forest, Essex; Chislehurst, Kent; Leith Hill, Surrey ; 
Lustleigh Cleeve, Dartmoor, Devonshire; near Penzance and Helminton, 
Cornwall; Adderbury Church, Oxfordshire; Hale End, Malvern, Wor- 
cestershire ; Shrewsbury, Shropshire; Aberdovey and Dolgelly, Merioneth- 
shire; Ayton, Newton, and Kildale Moors, Cleveland, Yorkshire; Mor- 
peth, Northumberland. New Galloway, Kirkcudbrightshire; Pentland

Form 1. lepidophora Florke, Clad. (1828) p. 70.—Podetia 
densely covered with minute, crowded, inciso-crenate, glaucous-grey 
squamules.—Cromb. Grevillea, xi. p. 111.—Cladonia pywidata p. 
chlorophea c. phyllophora (Wallr.) Mudd, Brit. Clad. p. 9. 
This form seems quite distinct from the type, but the younger podetia 
are as in it granulato-pulverulent. Its distinctive character no doubt 
depends upon age and the nature of the habitat; in the type itself podetia 
sometimes occur bearing a few scattered squamules. In the few speci- 
mens seen the apothecia are not numerous, 
Hab. On old brick walls and thatched roofs in lowland _districts.— 
Distr. Probably general, though seen only from Central and W. England, 
N. Wales, and N.E. Scotland.—B. M.: Lechlade, Oxfordshire; near 
Cirencester, Gloucestershire ; Conway, Carnarvonshire. Kinnordy, For- 
farshire ; Cults, near Aberdeen. 
Form 2. myriocarpa Cromb. Grevillea, xi. (1883) p. 111.— 
Podetia somewhat short, subturbinate; scyphi subdilated, proli- 
ferous from the margins, the prolifications narrow, multifid. Apo- 
thecia sessile, small, aggregato-confluent.—Cladonia pymwidata var. 
JSimbriata f. myriocarpa Coem. Clad. Belg. (1863) n. 58 ; Mudd, Brit. 
Clad. p. 10.—Brit. Exs.: Larb. Cesar. n. 58. 
A well-marked form, referred to C. fimbriata by Coemans, but belonging 
to this variety of C. pyxidata, from which it is distinguished by the pro- 
lifications of the scyphi. The apothecia in well-fruited specimens are 
very numerous and crowded, from pale-brown becoming reddish-brown. 
Hab. On the ground and on wall-tops in maritime and upland situa- 
tions.— Distr. Local and scarce in the Channel Islands, W. England 
S. Scotland, and the S. and N. Grampians—B. M.: St. Ouen’s Bay, 
Island of Jersey. Ozleworth Park, Gloucestershire; Malvern and Bewd- 
ley, Worcestershire. Castle Douglas, Kirkcudbrightshire; Achmore, 
Killin, Perthshire ; Glen Cluny, Braemar, Aberdeenshire.

squa mulose at the base, pale-greenish ; squamules small, scattered,
