460 LICHEN ACEI. [LECANORA. 
from upland to alpine situations.—Distr. Local in E, and N. England, 
N. Wales, and 8. Scotland ; general and plentiful on the Grampians; not 
seen from Ireland—B. M.: Near Norwich, Norfolk ; near Bury St. Ed- 
mund’s, Suffolk; Cwm Bychan, Merionethshire ; Ayton Mvor, Cleveland, 
Yorkshire; Teesdale, Durham. Pentland Hills, near Edinburgh; Ben 
Cruachan, Argyleshire ; Ben Lawers, Ben Vrackie, Blair Athole, Perth- 
shire; Katelaw and Clova mts., Forfarshire; Morrone, Ben Macdhui, 
Glen Dee and mts. about Invercauld, Braemar, Aberdeenshire; Glen 
Nevis, Inverness-shire. : 
Var. y. gonatodes Ach. Lich. Univ. (1810) p. 372.—Thallus 
subramulose, the branches divaricate, tortuous, gibbous, lobato- 
verrucose, difform. Apothecia very rare; spores 0,036-40 mm. 
long, 0,025-27 mm. thick.—Leight. Lich. Fl. ed. 3, p. 176 (excel. 
il. cit.); Cromb. Grevillea, xviii. p. 70.—Lichen gonatodes Ach. 
Prodr. (1798) p. 89. 
A peculiar and well-marked plant, though probably only a monstrosity, 
as observed by Acharius (Lich. Univ. J.c.). It is apparently extremely 
rare in fruit, the spores having only been recently described by Nylander 
(Lich. Nov. Zeland. p. 145) from specimens gathered in the Falkland 
Islands. 
Hab, On decayed mosses on the ground in alpine situations. —Distr. 
Only a single specimen found on the N, Grampians, Scotland (Leighton’s 
specimens from Wales belong to var. 8).—B. M.: Summit of Ben Avon, 
Braemar, Aberdeenshire. 
Subsp. L. subtartarea Nyl. Flora, 1882, p. 550.—Thallus more 
or less variolose or at length leprose (K+yellow, the variole 
CaCl + reddish). Apothecia somewhat small or submoderate 
(CaCl+ reddish), the thallme margin inflexed.—Cromb. Journ. Bot. 
1882, p. 274.—Leeanora tartarea subsp. pallescens f. leprosa Nyl. 
Not. Sillsk. pro F. et Fl. Fenn. Forh. v. (1886) p. 135. Lecanora 
tartarea forma leprosa Leight. Lich. Fl. ed. 3, p.175. Var. 3. arborea 
Mudd, Man. p. 156 pro parte. Lichenoides tartareum farinaceum, 
scutellarum umbone fusco Dill. Muse. 182, t. 18. f. 12. 
The reactions of the thallus and apothecia show that this belongs to 
L. tartarea, of which it is a good subspecies. When sterile it is easily 
recognized by the variolarioid thallus, which at times becomes almost 
entirely leproso-dissolved (form leprosa Nyl. 2. ¢., Cromb. Journ. Bot. J. c.). 
The apothecia, seldom present, are few, usually small and difform, occa- 
sionally crowned with the leprose thallus. 
Hab, On the trunks of old trees and on rocks in upland and subalpine 
situations.— Distr. Probably common in Great Britain and Ireland, 
though seen only from comparatively few localities —B. M.. Fridge 
Rocks, Sussex; New Forest, Hants; Falls of Beckey, 8. Devon; 
Roughton, Cornwall; Lynn Gwernon, Merionethshire ; Rosedale, York- 
shire. New Galloway, Kirkcudbrightshire; Roslin, near Edinburgh ; 
Barcaldine, Argyleshire; Craig Calliach, Craig Tulloch, and Ben Vrackie, 
Perthshire ; Morrone, Braemar, Aberdeenshire. Ronayne’s Island, Kil- 
larney, co. Kerry; Clonmel, co. Tipperary; Killerey Bay, Connemara, 
co. Galway.
