Trig, recuti'ta. Capsule on a stem, globular; wool black. 
(Plant stipitate, minute. Stipes dark-coloured. Sporangium mostly nod¬ 
ding, umbilicated, purplish-brown. Peridium curiously formed of a 
membrane intimately united with a series of longitudinal, parallel fibres, 
which are again connected by short transverse ones. After bursting the 
membrane gradually falls away from the interstices, leaving the skeleton 
a beautiful reticulated case, through the openings of which the sporidia 
escape. A highly beautiful microscopic object. Grev. 
Grev. Scot. Crypt. 153. E.) — Batsch 232. 
Head roundish, after bursting the lower half remains white and membra¬ 
naceous, and upon it rests an egg-shaped mass of a cotton-like texture. 
Linn. Suec. n. 1264. The figures of Bulliard are rather egg-shaped 
than globular, and taper downwards so as to form a stem, but in the 
plants now before me, the stem is thinnest upwards, and there is a hollow 
dot at the top of each unopened head. In an elegant drawing, by Mr. 
Knapp, which accompanied his specimens, the stem is equally distinct as 
in the figures of Batsch.

Trig, lichenoi'des. Permanent: stem awl-shaped: black: capsule

(E. Bot. 414. E.)— Dill. 14. 3. 
The basis black, pithy, elevated. Head hemispherical above, underneath 
plano-concave, with a round edge, resembling the crab’s eye of the 
apothecaries; ash-coloured, of the size of poppy seed. Linn. Suec. n. 
128T. I was favoured with specimens by Mr. Knapp, who remarks that 
he has never seen it grey, but always black.
