6. C. g leb u le n tum Nyl. ex Cromb. Grevillea, xv. (1886) p. 12.
■—Thallus effuse, thickly isidiose, glomuloso-diffraot, sublobate, and
membranaceous a t th e ciroumforonoe, olive-brown or blackish ; lobes
very small, subcntire or lacerate a t th e margins. Apotheoia and
spermogones unknown.— Lejotogium glebulentum Nyl. Cromb. Journ.
Bot. 1882, p. 272.
A peculiar plant externally diverse, but nearly allied to the preceding.
The thallus is rather thin, except where it is covered -with the
gvaniiloso-crustose isidia, by which it is almost obliterated, unless at the
circumference. Apotbecia aud spermogones are absent in tlie few specimens
seen.
Ilah. On moist limestone rocks in subalpine and alpine localities.—
Distr. In S. and N. Graiiipians, Scotland, rare.—B. AI.: Above Loch-
na-Gat, Ben Lawers, Perthsliire; Craig Guie, Braemar, Aberdeeiisliire.
7. C. tu rg id um Nyl. ex Lamy, Bull. Soo. Bot. F r. t. x xv. (1878)
p. 342.—Thallus thickish, roundly lobed, naked or granulate, d a rk -
olive or reddish-bla ck; lobes turgid, rugulose, ascending and somewhat
imbricate in th e centre, concave and undulato-plioate a t tho
circumference. Apotheoia moderate, urceolate or a t length somewhat
plane, reddish-brown or dark-brown, th e th allin e margin
turgid, more or less g ran u la te ; spores oblongo-ovoid, 3-soptate and
murali-looular, 0 ,0 2 3 -3 2 mm. long, 0 ,0 1 0 -1 2 mm. thick.—Lepto-

From all states of Collema pulposum or Collemodium plicatile this is
distinguisbed by the peculiar sublobato-fruticiilose thallus, which when
dry appears as if minutely verrucmformi-lobed. The apothecia, which
are sessile and normally urceolate, are usually numerous.
Ilah. On limestone and brick walls, also on calcareous and cretaceous
soil, in upland tracts.—Distr. General, though nowhere common, throughout
England, rare in the S.W. Highlands of Scotland, not seen from Ireland.—
B. AI.: Dunwich, Suffolk; Cbelsfield, K e n t; Reigate Hill and
Shiere, Surrey; near Hastings, Sussex ; Shanklin, Isle of Wight; Plymouth,
Devonshire; Wadebridge, Cornwall; Chew Alagiia, near Bristol,
Somersetshire ; Cliarfield, Gloucestershire ; Sevenhampton, Wiltshire ;
Barrington Hill and Alalvern, AVorcestershire ; Tetswortli, Oxfordshire ;
near Shiffiial, Shropshire. Appin, Argyleshire.
Var. p. dep ressum Cromb. Grevillea, xv. (1886) p. 12.—ThaUus
depressed, somewhat rosulate, very small, much scattered. Apotheoia
minute.
This peculiar variety evidently depends upon the nature of the habitat,
aud is probably a starved form of tlie typo. jAUlioiigb the thallus is
little developed, the apothecia are rather numerous.
