Genus XXXII. Stemonrres.: The plants of this)ge- 
nus dre usually inserted upon a membrane a 
the peridiums are spedunculated, and traver by an 
axis, which consists of a lengthening of the pedun- 
cle. 
 Stemonites typhoides. Sower. tab. 50. The white 
membrane of the common base supports a number of 
slender stalks, which traverse the peridium, and re- 
-main after the escape of the powder. The peridium is 
cylindrical, soft, of a milk-white colour when young, 
but becoming black afterwards. It bursts laterally m 
many places, and throws out a brown powder. ° It 
grows during the summer on rotten trunks of trees. 
Genus XKXIIL, Diverma. In this genus many in- 
dividuals arise from a common membrane, having a pe- 
ing, containing powder in- 
ridium with a double ore 
termingled with filaments. This genus bears the same 
relation to the Trichia as the Geastrum does to the Ly- 
on. 
Diderma floriforme. Bull. tab. 371. This plant is 
“altogether of a coriaceous ‘consistence, and of a: pale 
yellow colour. The base consists of a thick cbaious 
membrane, supporting many slender, smooth, cylindri- 
cal stalks, with a globular smooth head.’ At length the 
-outer bark opens into five or six unequal rays, exposing 
a true peridium, pear-shaped, wrinkled, and perma- 
nent, bursting irregularly, and emitting a brownish- 
coloured powder. 
Genus XXXIV. Rericutarta. This genus con- 
sists of plants, which are at first pulpy, shapeless, and 
soft. . Internally they present cells full’of powder, form- 
‘ing a kind of slender net-work ; finally, they are redu- 
ced into a fine powder. 
Reticularia hortensis. Sower. tab. 399. This is com- 
mon-on tan in hot-houses. It at first appears to fer- 
ment as it were in a kind of whitish froth, in afew 
hours becoming yellowish, and acing ae mixed with 
a powder ; at Hag oan grows fragile, flattens, and as- 
sumes a lightish n colour on the outside, being 
replete with dark powder, or seeds in irregular divi- 
sions within ; after which it soon falls to pieces. In 
the fresh state it smells not unlike rotten cheese, 
Genus XXXV. Spumaria. The plants of this ge- 
nus resemble the preceding, but their pulp conceals co- 
riaceous and membranaceous cases, inclosing the seeds. 
Spumaria mucilago. Sower. tab. 280. This plant is 
of a white colour, soft, and flaky like scum. Inter- 
nally the coriaceous cases are shaped like coral, and in- 
close a black powder. It dries up quickly, and by the 
touch is reduced to powder, nothing remaining but-the 
black cases. It grows upon the stalks and leaves of 
dead and living plants, 
Genus XXXVI. Levcogatta. In this genus the 
ridium is membranaceous, rounded, and filled while 
young with a liquid pulpy mass, afterwards changed 
into a powder mixed with a few filaments. This pe- 
ridium opens in a regular manner at the sides, or on the 
‘summit, 
Leucogalia argentea, Sewer. tab.272. This plant is 
sessile, or prolonged at the base into a very short pe- 
duncle. Its form approaches to spherical ; its colour is 
white when young, afterwards it turns red or brown: 
The pulp changes into a powder, at first grey, after- 
wards rust coloured, and at last brown. The seed. 
vessel bursts.at the side. This species grows solitary, 
on putrid trunks, in autumn. 
Genus XXXVII. Lycorerpon. The plants of this 
genus are composed of a peridium generally. globular, 
solid when young, with whitish close flesh, changing

into a powder intermingled’ with filaments. At matu- Fungi. 
rity it opens at the summit, in a manner more or less 7 
regular. Several species of this genus are so well known 
in this country by the name of Puff-balls, ‘as to render 
any farther description unnecessary. ; 
Genus XXXVII. Geasrrym. The plants of this 3S. Gras 
genus are globular at-first, then the external covering TRUM. 
opens at the top, and divides into many rays, curling 
backwards, and raising the peridium on a vaulted pe- 
destal. The peridium is globular, and at the 
summit by an orifice bordered by fading on The 
inside is full of brown powder, intermingled with fila- 
ments, dispersed, and indistinct. The. external cover= 
ing is coriaceous and thick, the internal is membrana- 
ceous ; between these there is sometimes found a fuga- 
ceous wrapper. ‘ : 
Geastrum hygrometricum. Sower. tab. 80. The ex- 
ternal covering is of a chesnut.colour, divided into five 
or six nearly equal rays, which are bent, backwards. 
The peridium is spherical and sessile, mouth ciliated, 
and usually bordered with a circle of a paler colour. 
For a more minute account of the species of this genus, 
the reader is referred to an excellent paper of Mr 
Trans. vol. ii. p. 32—62. ;

Tulostoma brumale. Bull. tab, 294, and 471. fig. 2. - 
This plant is of a white colour, the stem is cylindrical, 
generally glabrous, sometimes imbricated ; peridium 
globular, opening at the summit by a round orifice 
which is flat, ora little prominent. t grows in sandy 
grounds in winter, andin the beginning of spring.

Genus XL. Cyaruus. The fungi of this ge- 40. Cya-_ 
nus consist of little cups, the orifice of which, at first, is "vs. 
vested with a membrane, and the inside filled with a : 
viscid limpid juice ; afterwards the membrane. bursts, 
the liquid evaporates, and there remain-in the bottom 
of the cup from three to five lenticular capsules, adhe- 
ring to the base by a slender filament, and filled with 
jelly, in which grains are observed supposed to be 
seeds. ’ 
Cyathus striatus, Nidularia striata of Sower. tab. 
29. This plant is conical, woolly on the outside, and 
scored within. The capsules are smooth above and 
woolly beneath. It grows on the ground, and on rot- 
ten wood. . 
Genus XLI. Sricris. This genus exhibits little 41. sre 
membranaceous cups, half way inserted into the barks 11s. 
of trees, full of a substance not powdery, inclosing the 
seeds ; these are closed when young,. but open afters — 
wards into a cup. 1
