Similar to the preceding but differs in the large apothecia which
are pale-coloured from the beginning, and in the usually stouter
spores.

Yar. albovirella A. L. Sm.—Thallus effuse, thin, subleprose,
continuous, bright-green, a t times nearly evanescent, otherwise
as in the species.—Lecidea albovirella Nyl. in Flora Ix. p. 567

district.—E. M. Above Lough Feagh, Connemara, Galway (the only

Var. alboruhella A. L. Sm.—Thallus effuse, very thin, or
evanescent, whitish or greenish-white (K —, CaCl — ). Apothecia
small, convex, immarginate, yellow- or reddish-flesh-coloured,
within ^ colourless ; paraphyses slender, clavate a t the apices;
epithecium and hypothecium colourless ; spores linear- or fusiform-
oblong, 3-septate, thinner th an in the species, 0,014-21 mm. long,
0,002 mm. thick ; hymenial gelatine tawny-wine-reddish with
iodine.—Lecidea alborubella Nyl. in Flora Ixii. p. 205 (1879) ;
Cromb. in Grevillea vii. p. 28.
Nylander observes that while the thalline gonidia are normal
(glomerulose), there are also present hymenial gonidia consisting of
cylindrical erect syngonidia,—a not unfrequent occurrence in species
of this order. In the two specimens seen, which are very sparingly
fertile, the thallus is little visible, being for the most part overrun
by a Lepraria.
Hab. On calcareous rocks in a cave in a maritime locality.—E. M.
Derryclare, Connemara, Galway (the only locality).
Subsp. chlorotropoides A. L. Sm.—Thallus effuse, very thin,
subleprose, greenish (K —, CaCl — ). Apothecia minute, margined,
reddish-yellow, the margin usually darker ; perithecium violet in
th in section; hypothecium often pale-violet; paraphyses sub-
discrete, clavate a t the apices; spores fusiform-oblong, 1—3-
septate, 0,014—20 mm. long, 0,002—3 mm. th ick ; hymenial
gelatine bluish, the asci wine-red with iodine.—Lecidea cltloro-
tropoides Nyl. in Flora Ix. p. 567 (1877); Cromb. in Grevillea
VI. p . 112 ; Leight. Lich. PI. ed. 3, p. 346.
Subsimilar to the species, but differs in the colour of the apothecia
and m that of the excipulum and hypotheoium. In our specimen
6y Larbalestier the few apothecia are oohraceous or somewhat
reddish-yellow and immarginate. The spores are narrow and become
3-septate when mature. One of the two specimens from Kylemore is
associated with minute patches of a bright purple alga, which may
explain the sometimes pale-violet colour of the hypotheoium.

15. B. herbidula A. L. ,Sm.—Thallus effuse, thinnish, subleprose,
rimulose or rimulose-diffract, opaque, yellowish-green
(K + yellowish, CaCl — ). Apothecia minute, plane or somewhat
convex, pale-reddish, pale within, the margin thin, d a rk e r;
paraphyses not well discrete ; epithecium and hypothecium colourless
; spores fusiform, 1-3-septate, 0,011-18 mm. long, 0,0025
mm. th ic k ; hymenial gelatine bluish with iodine.—Lecidea
herbidula Nyl. in Flora Ix. p. 563 (1877); Cromb. in Grevillea
vi. p. 112 ; Leight. Lich. PI. ed. 3, p. 357.
A doubtful species perhaps referable to E. cuprea. Nylander has
described the thallus as having the characters of Qongrosira Kuetz.
with subohroolepoid filaments containing numerous large rotundate
greenish granules. Our specimen consists of a dense layer of cells of
some Palmellaceous alga ; I have been unable to find any apothecia.

16. B. byssoboliza A. L. Sm.—Thallus indeterminate, very
thin, continuous, opaque, greenish or greyish-green. Apothecia
small, somewhat prominent, yellow-flesh-coloured, concolorous
within, the margin paler, a t length undulate or scarcely distinct,
with a white, pubescent b a se ; paraphyses slender, discrete;
epithecium and hypothecium colourless; spores fusiform, 3-5-
septate, 0,023—27 mm. long, 0,003-4 mm. th ic k ; hymenial
gelatine pale-bluish then tawny-wine-coloured with iodine.—

Readily recognized by the pubescence at the base of the apothecia.
The specimen seen is only sparingly fertile.
