FUNGI 
The epidermis which remains in shreds, and the fibres, 
which, on account of their hardness, resist the devasta- 
tion, were formerly to be the seed-vessel, and 
the filaments parasitical plant. 
Secr. 2. Powder yellow.’ Uredo linearis, Sower. tab. 
189. This ies grows on the leaves of many of the 
grasses, forming linear patches visible on sides, 
rising under the epidermis, which at last bursts in the 
direction of the nerves. The powder is at first yellow, 
afterwards brown, com of ovoid globules. 
Secr. 8. Powder white. Uredo tragopogi. This is 
found on the leaves of the goat’s-beard, in the form of 
a white powder. _ 
Famity II. Pertdium membranaceous, filled with Pow= 
der not intermingled with Filaments. 
Genus XXVIE. Ecipium. The fungi of this genus 
+ em at first as simple tubercles, which soon open at 
@ summits into a circular orifice, more or less 1 
toothed. The inside contains a farinaceous neoth 3 
They are all parasitical, growing upon the leaves of 
living plants. 
+ Secr. 1. Tubercles scattered. Ecidium anemones. 
Lycoperdon anemones, Pultn. Lin. Trans. vol. ii. p 
311. This grows on the inferior surface of the leaves of 
the Anemone nemorosa, in the form of scattered tu- 
bercles. They appear at first under the cuticle, and 
afterwards burst forth like white buds, witha pore in 
the summit, and then expand into a cup with a laci- 
niated border. The powder is white, and com 
of ovoid globules, scarcely cohering. This. plant can 
searcely be mistaken for any of the. other parasitical 
fungi with which this anemone is infested, as.the Eci- 
dium punctatum, in which the. powder is brown, the 
Uredo anemones, and the Puccinia anemones. 
Secr. 2. Tubercles closing into a circular ring. Eci- 
dium tussilaginis. Sower. tab. $97, fig. 1. This grows 
upon the under surface of the leaves of several. species 
—— . The leaf appears with a reddish-white 
spot on the upper surface, and below the receptacles 
are disposed in spots, rounded and serrated, or of- 
“ formed into a ring. Powder orange, sometimes 
white. 
Seer. 3. Branched in irregular cluslers. Ecidium 
berberidis. Sower. tab. 897, fig. 5. This grows upon 
_ the back of the foliage of the common barberry, in 
rounded convex tufts, the space of each appearing on 
the upper surface like a red spot. ‘The common base is 
reddish, supporting small yellow tubercles, which di- 
vide at the summit into-a circular opening, the margin 
ee with fine oe Powder yellowish-orange. 
Found principally in the spring. 
Guus XXVIIL, Mucor. The:plants of this genus 
have a membranaceous globular or tufted receptacle, 
seated on a stem, at first watery and transparent, af- 
terwards opake, and full of naked powder, not mixed 
with filaments, and but little cohering. 
Mucor mucedo. Sower. tab. 378, fig. 6. This 
cies, which every one knows, is common on all fer- 
ee decaying vegetable or animal matter. 
The are simple and slender, bearing upon their 
summits a globular seed-vessel, at.first white and trans- 
parent, afterwards brown and opake, The seeds are 
numerous, round, and greenish while inclosed inthe 
seed-vessel.. This vessel bursts with an elastic 
force, as.:may be seen when viewing it under the mi- 
eroscope.

Genus XXIX. Liesa. The fungi here referred to 
have a sessile, membranaceous, brittle peridium, burst- 
ing in various ways, and containing a powder without 
en They are ‘destitute..of a membranaceous 
ase. 
Licea circumsissa.' Sower. tab, 258. \ This plant is 
sessile, rounded, and a little flattened. It opens irre- 
gularly across, and contains a golden yellow powder, 
a which one or two filaments may be discerned 
ata: It grows at the.end of autumn on dead 
wood, 
Genus XXX. .Tusvuuina. | The plants. of this ge- 
nus ss a membrane which supports. many sessile 
peridiums, whicli are generally cylindrical. The pow- 
der is destitute of filaments, 
Tubulina cylindracea, Bull. tab. 470, fig. 3. The 
peridiums are sessile, and rest upon a white obvious 
membrane: They are cylindrical and lengthened, and 
terminate in an obtuse point, of a rusty brown colour, 
with a white point: These burst irregularly towards 
the upper end, and allow. the rusty brown powder to 
escape.. This plant grows upon moist dead wood.. 
Famity III. Peridium membranaceous, filled with Pow= 
der, intermingled with Seeds. 
Genus XXXI. Tricuia. }The peridiums of this ge- 
nus are sessile or pedunculated, supported upon a mém- 
brane which is very. apparent in the young state of the 
plant. These inclose the filaments, which are attach- 
ed to a.stem, or to the partitions of the peridium, and 
oe pulverulent: globules. They are di- 
vided into several sections, which might with propriety 
be constituted into genera. 
Sgecr. 1. Peridium ovoid, spherical, sessile, or 
dunculated, bursting irregularly. These form the Sphe- 
rocarpus of Bulléard.  Trichiaturbinaia. Bull. tab. 481, 
fig. 1. The base is white, membranaceous, and very a) 
parent ; the stems are simple, smooth, slender, Tengthe 
ened, cylindrical, terminating in an orange-coloured 
peridium, at first in the form of a rounded tuft, after- 
wards as-if truncated, and finally concave at the sum- 
mit; at which time it might be taken for a Peziza, if 
the interior of the peridium were not filled with long- 
haired network, covered with a greyish-red powder. 
It grows on dead wood. ; 
Sect..2. Peridium bursting in such a manner as ta 
form a persisting calyx on the summit of the stalk. This 
is the Arcyria of Persoon.. Trichia nutans. Sower, 
tab. 260. The base consists.of a white coriaceous mem- 
brane, supporting the little fungi; the peridium is 
lengthened, becoming cylindrical, and at the same time 
decaying at the top, Tene at liberty the powder and 
the filaments. It grows upon dead wood. 
Szor. 3. Peridium destroyed in whole or in part, 
in such a manner as to leave anastamosing nerves, through 
which. the pomder issues, The Crebraria of Persoon. 
Trichia semi-cancellata, Sower. tab. 400. fig. 5. The 
base is a coriaceous white membrane, supporting nu- 
merous stalks, which are simple, striated, of a brown- 
ish-black colour, tapering towards the summit, straight, 
or leaning in old age. The peridium is globular at 
first, opake, of a fine yellow before and reddish after 
the emission of the seeds. The lower part is membra- 
naceous, and persisting in the form of a denticulated 
calyx ; the upper part is formed of fibres, disposed in a 
net-work, vanishing after the emission of the powder, 
which is yellow.
