PLATYSMA. | CRTRARIEL, 221 
from the preceding in the narrower laciniss, connivent at the margins, 
and when fertile in the position of the apothecia. With us it is sterile. 
Hab. On the ground among mosses in alpine places.— Distr. Known 
only from the summits of some of the higher N. Grampians, Scotland. 
—B.M.: Cairntoul and Cairngorm, Braemar, Aberdeenshire. 
b. Thallus subascending or appressed, more or less closely 
adherent, subdiscolorous ; Jacinise somewhat narrow. 
3. P. sepincola Nyl. Act. Soc. Linn. Bord. sér. 3, i. (1856) 
p. 295.—Thallus small, smooth, laciniato-lobed, olive- or chestnut- 
brown, beneath paler; laciniz decumbent or ascending, somewhat 
plane, the margins undulato-sinuate or crenate (K_, CaCl_), 
Apothecia submarginal, adnate, small or moderate, dark-brown or 
subconcolorous, shining, the margin thin, crenate; spores ellipsoid 
0,006-10 mm. long, 0,005—6 mm. thick.—Cromb. Lich. Brit. p. 26 
pro parte; Leight. Lich. Fl. p. 100 pro parte, ed. 3, p. 94 pro parte.

f. 2.—To this, from specimens in herbaria, is not referable the 
Lichen ov Cetraria sepincola of other British authors, which refers 
to the following species. 
A small plant, with the thallus rosulate, pulvinate, or sometimes effuse, 
and generally smaller when fertile than when barren. The small and 
crowded apothecia are rare in this country, as also the spermogones, 
which have the spermatia 0,006 mm. long, scarcely 0,001 mm. thick. 
Hab. On old pales and branches of trees, mostly firs, in mountainous 
districts.— Distr. Very local and scarce, in the N. Grampians, Scotland ; 
very doubtfully in N. England—B. M.: ? Teesdale, Durham. Glen 
Quoich and Glen Dee, Braemar, Aberdeenshire. 
4, P, ulophyllum Nyl. Flora, 1869, p. 442.—Thallus moderate, 
smooth or isidio-furfuraceous, lacero-laciniate, greyish- or pale chest- 
nut-brown, beneath paler ; laciniz subappressed or ascending, some- 
what narrow, variously divided, the margins undulato-crisp and 
white sorediato-pulverulent (K_,CaCl._). Apothecia submarginal, 
small, the margin subcrenulate or entire; spores as in the preceding 
species.—Cromb. Grevillea, xii. p. 75.-—Platysma scepincola var.

From P. sepincola, of which it has generally been regarded a variety, 
this is distinguished by the longer and broader, sometimes isidio-furfu- 
raceous laciniz, which when fully developed are somewhat flaccid, and 
by their crisp sorediate margins. The states by which it has been sup- 
posed to be connected with the preceding are merely young and non- 
isidiiferous conditions of this plant.. The small apothecia have only once 
been met with in this country rightly developed.
