Allied to L. erysibe, which it resembles in the appearance of the 
thallus, but differing in the early disappearance of the apothecial 
margin and in the more slender colourless paraphyses. It has not 
been recorded on the Continent as a distinct species, but may have 
been overlooked or included as a form of L. erysibe. LL. accessitans 
differs only in the more scanty thallus, probably owing to the shady 
habitat. 
Hab. On schistose rocks and walls in maritime and inland districts. 
—Distr. Rare in the Channel Islands, §.W. England and W. Ireland. 
—.M. Near Rozel, Jersey; Moulin Huet Bay, Guernsey; St. John’s,

16. L. umbraticula A. L. Sm.—Thallus effuse, thin, sub- 
leprose, greenish (K —,CaCl —). Apothecia small, rather plane, 
the margin disappearing, yellow ; paraphyses conglutinate, rather 
slender, the epithecium colourless ; spores fusiform, at first simple, 
becoming l-septate, 8-16 » long, 2-3 p» thick ; hymenial gelatine 
blue then wine-red with iodine.—Lecanora umbraticula Nyl. in 
Flora lxii. p. 205 (1879) ; Cromb. in Grevillea viii. p. 28 (1879)

Exsicc. Larb. Lich. Hb. (without a number) as Lecidea 
umbraticula. 
Not unlike a “ Biatora,” but with gonidia below the hypothecium. 
It is distinguished by the leprose thallus, the brightly coloured 
apothecia and the narrowly fusiform spores.
