paraphyses ; there is no specimen of it at tlic British Museum.
Nylander {I. c.) gives Sagedia (enea in Anzi Lich. Min. rar. n. 395 as a
synonym, but that plant lias been identified by him in MS. as
Verrucaria grisea.

7. A. stigmatella A. L. Sm. (non Alassal.).—Thallus greyish
or brownish, effuse, thin, smooth and shining. Perithecia black,
small, varying in size, often a mere point, semi-immersed and
liemispherical or more emergent and somewhat convex ; peritheciai
wall dimidiate ; paraphyses usually indistinct ; asci, elongate-
elliptical ; spores colourless, eloiigate-oblong, usually tapering a t
one or both ends, often becoming brownish, large, 1-septate,
0.027-40 mm. long, 0,007-010 mm. thick.—Lichen stigmatellus

Easily recognized by the large 1-septate spores, and usually by the
mixture of larger and smaller perithecia and spermogonia dotted over
the thallus.

8. A. analeptoides A. L. Sm.—Thallus whitish-grey, thin,
effuse. Perithecia black, moderate in size, hemispherical,
semi-immersed and slightly spreading a t the base, or small,
emergent and subglobose ; peritheciai wall dimidiate ; paraphyses
numerous, septate, lax or coherent ; asci elongate-clavate ; spores
elongate, fusiform-clavate, 1-septate, the cells with several guttulæ
and spuriously 3-5-septate, colourless or slightly tinged yellowish,
0,023-35 mm. long, 0,006-7 mm. thick.— Verrucaria analeptoides

Not to be confused with A. submiaans, the spores of which are
4-guttulate but finally 3-septate. It differs from A. stigmatella, with
which it has been associated, in the greyer more superficial thallus
and in the narrower guttulate spores. Nylander gives the size of the
spores at 0,086-50 mm. long, 0,007-010 mm. thick, but these measurements
are not borne out by an examination of Carroll’s specimen.

Dinish and Toro Mt., Killarney, Kerry ; Loughcooter, Galway.
9. A byssacea A. L. Sm.—Thallus filmy, whitish, thin, effuse.
Perithecia minute, black, globose, semi-immersed ; peritheciai
wall dimidiate ; paraphyses numerous, branched, free ; asci
elongate-clavate, about 0,070 mm. long, 0,017 mm. thick ; spores
8 in the ascus, fusiform, 1-septate (?), colourless, 0,015 mm. long,
0,004 mm. thick.— Verrucaria byssacea Tayl. in Mackay El. Hib,
ii. p. 89 11836) (non Ach. fide Leight. Angioc. Lich. p. 38).
Leighton suggests {I. c.) that Taylor’s species is identical with
Acrocordia hiformis, but the minute perithecia and the structure of
asci and spores are entirely distinct. There is only one small specimen
in the herbarium of the British Museum collected by Dr. Taylor ; the
spores are somewhat imperfectly developed, but so far as can be
determined they are 1-septate.
