EPHEBEIA. ] MAGMOPSFI. 29 
1. E. hispidula Nyl. Flora, 1877, p. 321.—Thallus decumbent, 
very much branched, rugulose, opaque, spinulose or verruculose 
towards the apices, olive-green or dark-brown. Apothecia ex- 
ternally subgloboso-tuberculose, pale, the epithecium impressed ; 
spores oblongo-ellipsoid, 0,010-0,015 mm. long, 0,004-5 mm. 
thick.—Cromb. Grevillea, xii. p. 89; Journ. Bot. 1885, p. 195.—Cor- 
nicularia hispidula Ach. Lich. Univ. (1810) p. 617. Cornicularia 
pubescens 8. hispidula Gray, Nat. Arr. i. p. 406.—To this belongs 
also Ephebe spinulosa Fr. fil. fide Nyl.l.c. ~ 
The thallus is somewhat stellately expanded, with the branches verti- 
cillately proliferous. From Ephebe pubescens it differs in being hispid and 
moncecious, as also in the structure of the apothecia. Of the few British 
specimens seen, only one is sparingly fertile. 
Hab. On damp quartzose and schistose rocks in subalpine districts.— 
Distr. Apparently local and scarce, being known only from N. Wales, and 
the 8. and Central Grampians, Scotland. B. M.: Cader Idris, Merioneth- 
shire; Snowdon, Carnarvonshire. Ben Lawers and Craig Tulloch, Perth- 
shire. 
Subsp. E. Martindalei Cromb. ea Nyl. Flora, 1883, p. 104.— 
Thallus scarcely spinulose: apothecia with the receptacle smarag- 
dine above (or somewhat bluish in thin section); spores 0,009- 
14 mm. long, 0,004-6 mm. thick.—Cromb. Grevillea, xii. p. 89; 
Journ. Bot. 1885, p. 195. 
This differs from the type, of which, as suggested by Nylander (J. c.), it 
is almost a variety, in the nearly smooth thallus and the colour of the 
receptacle. From Ephebe pubescens it could consequently with difficulty 
be distinguished in a sterile condition. 
Hab, On moist rocks in mountainous districts—Distr. Very local and 
scarce, having been gathered only in N.W. England.—B. M.: Mardale, 
Westmoreland. 
Tribe IV. MAGMOPSEI Nyl. Flora, 1875, p. 103. 
Thallus pyrenopsidian, consisting of syngonimia; gonimia mo- 
derate, without order. Apothecia forming a peridium; spores 
8nee, oviform, in oblong thece. Spermogones not seen rightly 
developed. 
This is a somewhat peculiar tribe, distinguished from all others in this 
family by the apothecia (if not parasitic, as Nylander is now rather 
inclined to think) constituting perdia—that is, a closed pyrenium without 
any true ostiole. It consequently holds an analogous relation among 
the Ephebacet to Peridiei among the Lichenacei. From the Phylliscodet 
it differs in the characters of the apothecia and the gonimia. 
7, MAGMOPSIS Nyl. Flora, 1875, p. 103.—Thallus indeter- 
minate; syngonimia glomerulose or granuloso-difform, greenish- 
yellow, gonimia pale-glaucous or concolorous with the rest of the 
thallus. Apothecia small, the peridium (under the microscope)
