32 MUSCI-ACROCARPI-PERISTOMI. [Trichostomum.
15. D. cylindricus, (cylindrical Didymodon); stem short
simple, leaves from a broad base setaceo-capillary spreading on all
sides flexuose, capsule cylindrical inclined, lid conical blunt.
Trichostomum cylindr. Hedw. Sp. Muse. p. 107. t. 24. f. 7— 13.
Wahl. Lapp. p. 332.— Dicranum cylindricum, Web. et Mohr.
Ditch bank, near Orange Grove, Belfast, Mr. Drummond. Fr.
Nov.—For the addition of this species likewise to the British list,
we are indebted to Mr. Drummond. It is entirely distinct from any
other of this country : and bears fruit very sparingly in the station just
mentioned.
17. Trichostomum. Hedw. Fringe-Moss.
Seta terminal. Peristome single, of 16 equal teeth divided to
the base, or 32 placed together in pairs. Calyptra mitriform.
(Muse, Brit. t. 2.)—Named from Sg/g, a hair, and (fro^x, the
mouth, on account of the slender capillary teeth at the mouth
of the capsule.
* Fruitstalks curved.
1. T. patens, Schwaegr. (spreading Fringe-Moss); stems
elongated procumbent, leaves lanceolate acuminate carinated
their margins recurved, fruitstalks curved, capsule oblongoovate
furrowed, lid rostrate. Schwaegr. Suppl. v. I. p. 152.
t. 37. Drum. Muse. Scot. v. 1. n. 43. Muse. Brit. ed. 2. p. 104.
t. 19. (excl. var. (3.)—Dicranum patens, Fl. Brit. p. 1213.
E. Bot. t. 1900. Bryum patens, Dicks. Or. Fasc. 4. t. 4.

Dill. Muse. t. 17. /. 30.
Rocks in mountainous regions, frequent. Fr. Summer.—The upper
leaves are sometimes slightly piliferous at the points.
2. T. ? fundle, Schwaegr. (cord-like Fringe-Moss); stems
elongated ascending, leaves lanceolate acuminate carinated
their margins recurved hair-pointed, fruitstalks curved, capsule
oblongo-ovate furrowed, lid rostrate, teeth often cleft only
at the point. Schwaegr. Suppl. v. 1. p. 150. t. 37.— T. patens,
/S. Muse. Brit. ed. 2. p. 104.
Rocks, rather scarce. Argyleshire, Capt. Carmichael. Clova, Mr. T.
Drummond. Near Plymouth, and near Penzance, Rev. J. S. Tozer. Fr.
Summer.—I agree with my valued correspondent last mentioned, that
this is a very puzzling moss. That gentleman has shown the peristome
to be very different from that of T. patens, with which I had
united it, and indeed that in many respects it is more allied to Grimmia
trichophylla : but it is much stouter in all its parts and has the leaves
more lax.
** Fruitstalks straight.
• 3. T. lanuginosum, Hedw. (woolly Fringe-Moss); stems elon-
gated subpinnate, leaves lanceolato- subulate acuminate their
long diaphanous points serrated, margins recurved, capsule
ovate, fruitstalks short on lateral branches, lid rostrate. Hedw.
St. Cr. v. 3. L 2. Turn. Muse. Hib. p. 38. Fl. Brit. p. 1240.
