100 LICHENACEI. [conrocyBR. 
Durham; Bassenthwaite Lake, Cumberland. Calderbank, near Glasgow ; 
Blair Athole and Aberfeldy, Perthshire. 
Form fulva Fr. Lich. Eur. (1831) p. 382.—Stipes short, some- 
what stout, capitulum hemispherical ; otherwise as in the type.— 
Mudd, Man. p. 262; Leight. Lich. Fl. ed. 3, p. 46; Cromb. Gre- 
villea, xv. p. 14.— Mucor fulvus Linn. Sp. Pl. ed. 3 (1764) p. 1655, 
This form differs only in the shorter, stouter stipes and the form of the 
capitulum. Where the plant is abundant, transition-states may be seen 
in the same specimen. 
Hab. On dead stems and mosses on walls and on the ground in up- 
land tracts.— Distr. Local and scarce in W. England, and amongst 
the Central Grampians, Scotland—B. M.: Oswestry, Shropshire. Blair 
Athole, Perthshire. — 
2. C. sulphurea Nyl. ex Cromb. Grevillea, xv. (1886) p. 14.— 
Thallus effuse, leprose, very thin, greyish or greyish-white, often 
obsolete. Apothecia small, sulphureo-pulverulent ; stipes short, very 
slender ; capitulum minute, globose; sporal mass yellow; spores 
0,0025-0,003 mm. in diameter.— Lichen sulphureus Retz. Vet. Ak. 
Handl. 1769, p. 249. Coniocybe furfuracea c. sulphurella Fr. Mudd, 
Man. p. 262; Cromb. Lich. Brit. p. 14; Leight. Lich. Fl. p. 47, 
ed. 3, p. 46. 
Though regarded as a variety of the preceding, differing chiefly in the 
colour of the thallus and the smaller apothecia, this appears to be specifi- 
cally distinct. It definitely and constantly preserves its own proper type, 
and it has smaller gonidimia. In the British specimens the thallus is 
well developed, with the apothecia somewhat scattered. 
Hab. On semiputrid trunks of old oaks in wooded upland tracts. — 
Distr. Extremely local and scarce, in 8. and N. England.—B. M.: New 
Forest, Hants; Teesdale, Durham. 
3. C. pallida Fr. Sched. Crit. i. (1824) p. 3.—Thallus very thin, 
leproso-pulverulent, white, often obsolete. Apothecia small; stipes 
moderate, stout, hyaline or yellow, rarely brownish above ; capitu- 
lum globose ; sporal mass white or pale; spores 0,004-10 mm. in 
diameter.—Mudd, Man. p. 262; Cromb. Lich. Brit. p. 14; Leight. 
Lich. Fl. p. 47, ed. 3, p. 46.—Calicium pallidum Pers. Ust. Ann. 
(1794) p. 20, t. 3.ff£.1, 2. Calicium peronellum Turn. & Borr. Lich. 
Br. p. 158; Sm. Eng. Fl. v. p. 141. Phacotiwm cantherellum Gray, 
Nat. Arr. i. p. 484. Lichen cantharellus Eng. Bot. t. 2557. 
This may easily be recognized from the preceding, to which in the 
colour of the thallus it approximates, by the hyaline and stout stipes, 
and the colour of the sporal mass. 
Hab. On stumps and trunks of old decayed trees in shady places in 
upland tracts.—Distr. Only a few localities in Central and N. England, 
though what appears to be the barren thallus has been met with else- 
where.—B, M.: Teesdale, Durham; near Hexham, Northumberland.
