—lh a llu s effuse, white or yellowish, somewhat granular or
mealy, with scattered raised roundish flat verrucæ. Apothecia
immersed in the verrucæ, black, small, punctiform, angular or
flexuose, often confluent, base confluent, blackish-brown ; spores
elongate-fusiform, slightly bent, colourless, 2- or 3- (?) septate,
0,036-48 mm. long, 0,004 mm. th ic k .-L e ig h t. Angioc. Lich,

Essentially an inhabitant of southern lands (S. France, &c.). The
only specimen in the British Museum is imperfectly developed, and
it has been impossible to find spores ; it agrees externally with the
diagnosis given for the species.

Thallus whitish, thin, granular, continuous, with small roundish
verrucæ. Apothecia black, aggregate in the verrucæ ; hypothecium
blackish ; paraphyses not distinct, spores oblong-clavate,
3-septate, 0,011—16 mm. long, 0,0035 mm. thick, ra th e r thicker
upwards ; hymenial gelatine bluish, then sordid-yellow with
iodine.—Cromb. in Grevillea viii. p. 29.

lh a llu s crustaceous. Algal cells Trentepohlia. Apothecia
immersed in more or less prominent verrucæ, roundish or
elongate, simple or branched ; apothecial wall well-developed,
forming a dark margin ; paraphyses simple ; asci elongate, 4-8-
spored, ra th e r thickened a t the tip s ; spores elongate, pluriseptate,
colourless.
Essentially a tropical genus only sparingly represented in Europe.
Owing to the elongate apothecia it is perhaps more characteristically
graphideine than the other genera of the order. The spermogones
are unknown.
1. G. labyrinthica Ach. Syn. p. 107 & in Trans. Linn.
Soc. xii. p. 38, t. 2, f. 1 (1818).—Thallus whitish or brownish-
olivaceous, thin, with white rather flat subprominent pulverulent
verrucæ. Apothecia small, elongate, forming a reticulation of
black lines on the verrucæ; hypothecium brownish, darker
downwards ; paraphyses slender, crowded, rather in d istin c t;
spores linear-oblong, 3-5-septate, becoming slightly brownish.—

Thallus foliaceous, squamulose or crustaceous,^ sometimes
developed under the bark (hypophloedal), or wanting. Algal
cells Cyanophyceæ or Chlorophyceæ. Fruiting body a roundish
perithecium immersed or superficial, usually opening above by a
pore (ostiole)-
The series is marked by the character of the fruits resembling th at
of the Pyrenomyoetes among fungi. The genus Strigidla (see Part I.
p. 12) is omitted, as the only British species referred to it, Str. Bahing-
tonii, is a fungus. The genera classified by Crombie {I. c.), under
Ser. vii. Peridiodei, have also been included under Pyrenodei, with
the exception of the genus Endoooccus, which is now recognized as
consisting of species of fungi parasitic on the thallus and fruits of
various Lichens.
Myriangium (Family IV. M y r ia n g i a c b i ) (see Part I. p. 15) is also
now regarded as a genus of Fungi.
Tribe XX. P Y R E N O C A R P E I .
Thallus foliaceous, squamulose or variously crustaceous, sometimes
obsolete. Perithecia immersed in the thallus or more or
less superficial, scattered or united in a stroma, the outer wall
soft and waxy or carbonaceous ; contents soft and mucilaginous,
often interspersed with oil-drops, sometimes enclosing hymenial
gonidia ; paraphyses simple or branched, sometimes disappearing
or altogether wanting.
AVith tlie exception of the Order Pyrenidiaceæ (Tribe iii. Pyremdiei,
Part I. pp. 8 , 81), the lichens of this tribe contain gonidia belonging
to the group of green Algæ, Chlorophyceæ. The Order Astrotheliaoeæ
is not represented in the British Isles. Astrothelium parmularia
Leight. Lich. Fl. p. 467 ; ed. 3, p. 499 (SpJuma parmidana Berk, m
Hook. Journ. Bot. iii. p. 19 (1851)) is a fungus.
The following N atu ral Orders are British : —
