FOLIA undique erecto-patentia, inferiora breviora conco-
loria, omnia madore luteo- vel soepe nigro-yiridia,
lanceolata, concava, margine plerumque subm-
Curvo, apice longe acuminata, incana, serrulata,
nervo valido concolore, sub apicem incanum
evanescente, instructa; siccitate nigricantia, âp-
pressa, quandoque contorta.
Seta terminalis, foliis longior, sed longitudine mire

quandoque torta. .
Capsula erecta, ovata, primum luteo-vindis, demum
fusca, lævis, ore rubro. . .
Operculum conico-subacuminatum, rectum, basi rubrum.
Annulus simplex. . .
Calyptra mitræformis, basi quadn-quinquenaa, pai-
lide fusca, apice intense fusca.
Peristomium simplex, rubrum, dentibus sedecim, li-
beris, transversim striatis, bifidis vel integris, rarius
rimis longitudinaliter perforatis.
Root small, between fibrous and tomentose, reddish
brown.
Stems about an inch high, erect, branched, above some-
times in a fastigiate manner, and forming small
and thick, somewhat cushion-like patches.
Leaves ou every side, erecto-patent, the lower ones
shorter, of one colour, all of them yellow or often
a blackish green, lanceolate, concave, generally
Somew hat incurved at the margin, the apex much
lengthened put, hoary and serrulate, furnished
with a strong nerve of the same colour, vanishing
- just below the hoary point; when dry they become
blackish, appressed, and sometimes twisted.
Fruitstalk terminal, longer than the leaves, but it
varies much in length, from two to three lines,
erect or a little curved, never arcuate, yellowish;
when diy somewhat twisted.
Capsule erect, ovate, at first yellow-green, at length
brown, smooth,- red at the mouth.
Operculum conical, somewhat acuminate, straight, red
at the base.
Annulus simple.
Calyptra mitrceform, the base four- or five-cleft, pale
brown, the apex deep brown.
Peristome simple, red, of 16 unconnected teeth,
transversely striated, bifid or entire, rarely perforated
with longitudinal openings.

has the operculum more obtuse, and the teeth of the peristome quite entire, not even peifoiated.

In all these a regular gradation may be observed in the length of the fruitstalks.
