Lichen Swartzii Ach. Prodr, (1798) p. 54, t. 1. fig. 2 (non bonum) ; 
Dicks. Crypt. fase. iv. p. 23. 
The form of the thallus at the cireumference and that of the apothecia 
are the distinguishing marks of this variety. In the former respect, how- 
ever, the radii are visible only in entire specimens and are sometimes 
absent even in the growing plant, The apothecia are occasionally much 
deformed. 
Hab. On rocks in mountainous districts.—Distr. Only very sparingly 
on the S. and N. Grampians, Scotland.—B. M.: Ben Cruachan, Argyle- 
shire; Morrone, Braemar, Aberdeenshire. 
Subsp. 1. L. subradiosa Nyl. Flora, 1872, p. 549.—Thallus and 
apothecia as in the type, but the former with different reaction. 
_ Thallus CaCl+ orange passing into reddish. Apothecia (epithecium) 
CaCl+ yellow.—Cromb. Grevillea, xix. p. 60. 
Nylander /. c. says that this may be only a state of Z. glaucoma, mixed 
up with which it frequently occurs in the E. Pyrenees, though not in 
the very few British specimens as yet detected. These, apart from the 
reactions, from a diagnosis given me by Mr. Johnson present no special 
marks of distinction. 
Hab. On stones of a wall in an upland district— Distr. Very local and 
scarce in N.E. England (Sinderhope, East Allendale, Northumberland). 
Subsp. 2. L. bicincta Nyl. Act. Soc. Sc. Fenn. vii. (1863) p. 398. 
—Thallus as in the type. Apothecia glauco-pruinose, with double 
margin, a thalline and within this a black proper margin; spores: 
0,011-14 mm. long. 0,007-8 mm. thick.—Lecanora bicincta Ram. 
Mus. Nat. Hist. Mém. xiii. (1825) p. 248. 
At least a good subspecies well characterized by the zeorine apothecia, 
though in other respects agreeing with L. glaucoma. The type does not 
occur in Britain, but only the variety that follows. 
Var. 3. lecideina Cromb. Grevillea, xviii. (1890) p. 68.—Apo- 
thecia small, lecideoid, black, more or less pruinose, the proper. 
margin slightly prominent and flexuose.—Lecanora rimosa b. lecidina 
Schaer, Enum. (1850) p. 71. ZL. glaucoma var. ceerulata (Flot.) 
Leight. Lich. Fl. p. 215, ed. 3, p. 204. 
Probably only a form, as in the single British specimen seen a few 
young apothecia are zeorine. Otherwise they are lecideine, convex and 
ageregate, with the thalline margin obliterated. 
Hab. On a quartzose rock in a mountainous district.—Déstr. Found 
only very sparingly on one of the N. Grampians, Scotland.—B. M.. 
Morrone, Braemar, Aberdeenshire. 
101. L. subcarnea Ach. Lich. Univ. (1810) p. 8365.—Thallus sub- 
determinate, yellowish. white, rimoso-areolato-granulate (K+ yellow, 
then deep orange-red). Apothecia moderate, plane or’ convex, some- 
times conglomerate and difform, flesh-coloured or livid-testaceous,
