LECANORA. | LECANO-LECIDEEI. 447 
what plane, biatoroid, fleshy-yellow or subyellowish, colourless 
within; paraphyses submoderate; epithecium colourless; spores 
fusiform, simple, or at times thinly 1-septate, 0,008-16 mm. long, 
0,002-3 mm. thick ; hymenial gelatine wine-reddish with iodine.— 
Cromb. Grevillea, viii. p. 28. 
Allied to var. 8 of the preceding species, but differs in the thallus and 
the thinner spores, the form of which Nylander says are as in Lecidea 
globulosa. The single fragmentary specimen seen is well fertile. The 
spermogones have the spermatia 0,014-19 mm. long, 0,0005 mm. thick. 
Hab. On shady calcareous rocks in a maritime district.—Distr. Ex- 
tremely local and scarce in N. W. Iveland.—B. M.: Kylemore, Connemara, 
co. Galway. 
138. L. spodophxiza Nyl. Flora, 1873, p. 290.—Thallus deter- 
minate, moderate, granuloso-verrucose, greyish, thinly white-fim- 
briate at the extreme circumference (K—, CaCl—) Apothecia 
small, somewhat plane, badio-reddish, the thalline margin subentire ; 
spores oblong or fusiformi-oblong, simple or often spuriously 1-septate, 
0,009-18 mm. long, 0,004—6 mm. thick ; epithecium pale-brownish ; 
hymenial gelatine pale-bluish, then wine-coloured with iodine.— 
Cromb. Grevillea, ii. p. 89; Leight. Lich. Fl. ed. 3, p. 220. 
_ Has much the appearance of a young state of LZ. poliophea. In the 
specimens seen the thallus occurs chiefly in small patches, which at times 
become more or less confluent. The apothecia are only sparingly present, 
with the thalline margin persistent and scarcely prominent except in a 
young condition. The spermogones have the spermatia 0,018-25 mm. 
long, scarcely 0,0005 mm. thick. 
Hab. On granite maritime rocks.—Distr. Confined to one of the 
Channel Islands, and there very sparingly—B. M.: Mont Orgueil, Island 
of Jersey. 
139. L. act#a Nyl. Flora, 1873, p. 290.—Thallus determinate, 
moderate or thinnish, unequal, rimoso-diffract, greyish-leaden- 
coloured, bluish and thinly white-fimbriate at the circumference 
(K—,CaCl—). Apothecia small, somewhat prominent, at length 
convex, biatorine, blackish; spores ellipsoid or subfusiform,,1-sep- 
tate, 0,012-14 mm. long, 0,0045 mm. thick ; epithecium dark bluish ; 
paraphyses thickish, jointed; hymenial gelatine bluish (the thecz at 
length violet) with iodine.—Cromb. Grevillea, ii. p. 89. 
A peculiar species, externally similar to Z. Ralfsi, but differing in the 
character of the thallus at the circumference, and in the colour of the 
epithecium. More important anatomical differences are the smaller 
spores and especially the character of the spermogones, which latter 
places it in this section. In the two fragmentary specimens seen the 
apothecia are very sparingly present. The spermogones also are rare, 
with the spermatia, 0,016-20 mm. long, 0,001 mm. thick, 
Hab. On rocks in a maritime district.—Distr. Very rare in one of the 
Channel Islands.—B. M.: Boulay Bay, Island of Jersey.
