108 LICHENACEI. [GoMPHILLUS, 
superficial resemblance to the Calicie?, yet, unless it constitutes a separate 
and intermediate tribe, it may, from its general habit, be referred as an 
aberrant genus to the Beomycetet. 
1. G. calicioides Nyl. Act. Soc. Linn. Bord. sér. 3, i. (1857) 
p. 146; Syn. i. p. 175, t. 7. £.3.—Thallus very thin, somewhat 
varnished, effuse or obsolete, greyish or greyish-green. Apothecia 
small, pale ; stipes narrowly canaliculate ; capitulum subturbinate, 
dark or blackish; spores very long, cylindrical, fasciculately con- 
stipate in vertical canaliculi of the thalamium, 60-100-septate, 
0,160-0,200 mm. long, and sometimes of even greater length._—

Beomyces calicioides Del. in Dub. Bot. Gall. (1830) p. 636. 
This plant has a somewhat fungoid aspect, but analysis shows it to be 
a lichen. The thallus is normally orbicular; but is at length more or 
less widely spreading. Its varnished appearance and the numerous 
beomycetoid apothecia easily distinguish it. The frequent spermogones 
are brownish-black, the spermatia about 0,001 mm. long, scarcely 
0,0005 mm. thick. 
Hab. Incrusting decaying mosses on the ground in upland situations.

smaller, more shortly stipitate-—Carroll, Journ. Bot. 1867, p. 254;

In this form, differing from the type only in the smaller apothecia, the 
stipes is occasionally so short that the apothecia are almost sessile on 
the thallus. 
Hab. Incrusting decaying mosses on trees and boulders in shady places 
in wooded upland tracts.—Distr. Local and scarce in the W. Highlands, 
Scotland, and in 8.W. Ireland.—B. M.: Barcaldine, Argyleshire. Di-

27. BHEOMYCES Pers. Ust. Ann. 1794, p. 19; Nyl. Syn. 1. 
p. 175.—Thallus crastaceous, granuloso-pulverulent or squamose. 
Apothecia sessile or stipitate, opaque, biatorine, the stipes formed 
of the constricted extended hypothecium and of longitudinal fila- 
mentose elements; hypothecium pale; spores usually 8ne (in 
elongato-cylindrical thecee), ellipsoid or fusiform, simple or septate, 
colourless ; paraphyses slender, not very discrete ; hymenial gelatine 
either not tinged, or pale bluish with iodine. Spermogones tuber- 
cular, with jointed sterigmata and straight, cylindrical spermatia. 
Although the apothecia are more or less stipitate, this genus, were it 
not for the spermogones, might be included amongst the Lecideei. No 
doubt the spermogones equally differ from those of this series, so that
