Thallus effuse, thin, opaque, subleprose, rimoso-diffract, greyish- 
brown (K—, CaCl—). Apothecia small, blackish, the thalline 
margin subentire; spores ellipsoid, usually 1-septate, 0,011—16 mm. 
long, 0,006-7 mm. thick ; paraphyses slender, brown at the clavate 
apices; hymenial gelatine bluish, then violet, with iodine.—Cromb. 
Grevillea, v. p. 106; Leight. Lich. Fl. ed. 3, p. 221. 
A peculiar plant having the aspect of some ally of Z. sophodes. In 
the two specimens seen the thallus is rather scattered and little visible, 
being overrun by a foreign plant, but the apothecia are frequent. 
Hab. On sandstone rocks in maritime tracts,— Distr. Local and scarce 
in N.W. Ireland.—B. M.; Killery Bay and Kylemore Lake, Connemara,

Usually not rightly separated by authors from LZ. exigua and L. 
roboris. The thallus is generally small, macular, thin, distinctly limited 
by the hypothallus, rarely thickish and more expanded. It is always well 
fertile, the apothecia being chiefly central and becoming angulose from 
mutual pressure. 
Hab. On trunks of trees, especially ash, in wooded maritime and upland 
tracts.—Dist. Local and scarce in 8., W., and N. England, and in 8. 
Wales.—B. M.: New Forest, Hampshire ; near Anstey’s Cove, Torquay,
