eucarpa Nyl. Bot. Not. 1863, p. 163. 
Looks as if it descended from ZL. glaucocarpa (athalline), but from the 
type of the apothecia it belongs to this section. These are either simple 
and umbilicately affixed or several connate in a common umbilicus. The 
lower stratum of the hypothecium, as observed by Nylander, is thin, 
black. The peculiar fructification at once distinguishes it from all the 
allied species. 
Hab. On granitic rocks in maritime districts.—Distr. Very local and 
scarce in the Channel Islands and those of S.W. England.—B. M.: West 
coast of Guernsey. Scilly Islands, Cornwall. 
195. L. privigna Nyl. Flora, 1873, p. 69.—Thallus obsolete. 
Apothecia plane, small or submoderate, usually approximate, rounded 
or angulose, brick-red when moist, blackish when dry, the margin 
black, entire or flexuose, persistent; spores 0,003-4 mm. long, 
0,0015 mm. thick; hypothecium colourless ; paraphyses slender, 
jointed, brownish at the conglutinate apices; hymenial gelatine 
bluish, then sordid or slightly tawny with iodine.—Cromb. Grevillea, 
xix. p. 58.—Lecanora fuscata var. privigna Cromb. Lich. Brit. p. 56.

Apparently a distinct species intermediate as it were between L. 
pruinosa form nuda and less plicate states of L. simplex. From both, 
however, it differs in the characters given, though more nearly allied to 
the latter. The apothecia are frequently in groups with the margin 
constantly black. 
Hab. On arenaceous and granitic rocks in maritime tracts.— Distr. 
Only here and there in the Channel Islands, 8. and N. England, and the 
E. coast of Scotland.—B. M.: St. Brelade’s Bay, Island of Jersey ; Island 
of Alderney. Tyneside, near Bywell, Northumberland. South of Bay 
of Nigg, Kincardineshire ; Old Machar, near Aberdeen. 
196. L. hypophwa Nyl. Flora, 1870, p. 34.—Thallus effuse, thin, 
granulato-unequal, greyish or greyish-green (K —). Apothecia 
submoderate, lecideine, blackish or dark-sanguineous, at first plane 
with the margin subcrenulate or unequal, black, at length convex 
with the margin excluded; paraphyses moderate or thickish, jointed, 
amber-brown at the apices; hypothecium colourless, infuscate 
beneath ; spores oblong, 0,005-6 mm. long, 0,0015 mm. thick; 
hymenial gelatine bluish, then wine-red or tawny-reddish with iodine. 
—Cromb. Journ. Bot. p. 97; Leight. Lich. Fl. p. 186, ed. 3, p. 172. 
Very near the preceding species, but differs in the character of the 
paraphyses and the darker lower stratum of the hypothecium, It would 
differ also externally in the presence of a thallus were this really proper, 
which is rather doubtful. The two British specimens are well fertile. 
Hab. On granitic stones of a wall in a lowland submaritime district.— 
Distr. Extremely local and rare in N.E. Scotland.—B. M.: Near Old 
Machar Cathedral, Aberdeen.
