Form pleorytis Ach. Syn. (1814) p. 161 (excl. syn.).—Thallus 
determinate, thickish, granulate, yellow. Apothecia crowded, con- 
colorous, the thalline margin inflexed and crenulate.—Cromb. Gre- 
villea, xviii. p. 69.—Parmelia varia 8. pleorytis Ach. Meth. (1803) 
p. 178. 
Differs chiefly in the character of the thalline margin, which is as if 
incised. This, however, is less visible in the young apothecia of the only 
British specimen (fragmentary). 
Hab. On old pales in an upland district.—Distr. Only very sparingly 
in the 8, Grampians, Scotland.—B. M.: Lawers, Killin, Perthshire. 
116. L.-conizea Nyl. Flora, 1872, p. 249.—Thallus effuse, 
thickish, leproso-pulverulent, whitish-yellow (K + yellow, CaCl—). 
Apothecia lecanorine, small or moderate, plane or somewhat: convex, 
pale or pale flesh-coloured, at length brownish ; the thalline margin 
entire or flexuose, somewhat thickish, pulverulent ; spores ellipsoid, 
0,010-14 mm. long, 0,0045 mm. thick; hymenial gelatine bluish, 
then tawny-yellow with iodine.—Cromb. Trans, Essex Field Club.

Well distinguished from Z. varia by the paler, leprose thallus and the 
pulverulent margin of the apothecia. In a young state the thallus is 
thinnish, but subsequently becomes rather thick and spreads extensively. 
The apothecia are numerous when present (for the plant is often sterile), 
and become dark-brown and flexuose in age. 
Hab. On old pales, chiefly oak, in lowland and upland districts.— Distr. 
Local in 8., Central, W. and N. England, but abundant where it occurs.

117. L. conizeoides Nyl. ea Cromb. Journ. Bot. 1885, p. 195.— 
Thallus effuse, somewhat thickish, leprose or subleprose, pale- or 
whitish-yellow (Kf+ yellowish, CaCl—). Apothecia lecanorine, 
submoderate, innato-sessile, pale-yellow or livid-brownish ; the thal- 
line margin persistent, crenulate and often inflexed ; spores oblong, 
0,009-11 mm. long, 0,005-7 mm. thick ; hymenial gelatine bluish, 
then sordid with iodine. 
Intermediate between Z. varia and ZL. conizea, to which latter the 
thallus is almost similar, though the spores are more turgid. From Z,
