4. C. juniperina Ach. Meth. Lich. p. 298 (1803) (excel. var. 
pinastri).—Thallus of crowded ascending lobes, crisp and deeply 
crenate at the upturned margins, generally marked with brown 
papille, citrine or greenish-yellow, rather paler beneath, the 
medulla more deeply coloured (K —, CaCl—). Apothecia 
marginal on the upper surface of the laciniz, rather small, 
reddish or brown, with narrow corrugate or denticulate 
margin ; spores ellipsoid, 6-9 » long, 4-6 p thick.—S. F. Gray

The few authentic specimens in the herbarium are less highly 
developed than those collected in higher altitudes. Only one of the 
specimens (from Teesdale) is sparingly fertile. The spermatia are 
elongate and slightly thicker at one end; they measure 7p long, 
ly thick. Hudson’s Lichen juniperinus according to Smith (Engl. 
Fl. t. 194) as well as Lightfoot’s plant (Fl. Scot. ii. p. 836) are forms 
of Xanthoria parietina. 
Hab. On the trunks of old pine trees in mountain woods.— 
Distr. Extremely local and rare in N. England and among the 
N. Grampians, Scotland.—B. M. Near High Force Inn, Teesdale,

appressed, the lobes roundish, plane and sometimes imbricate, 
greenish-yellow, the margins intensely yellow-pulverulent, the 
medulla also deeply coloured ; beneath concolorous (K —, CaCl—). 
Apothecia as in the preceding species, very rare.—C. juniperina

are sterile. 
Hab. On the trunks of old firs and on larch palings in upland

among the Grampians, Scotland.—B. M. Framlingham, near Norwich,
