Under trees. Bristol, Dr. Stephens. Sometimes half exposed,
as pointed out to me at Bristol by Mr. Broome and
Mr. Thwaites. Colour exactly that of a carrot. Communicating
to paper a lemon-coloured stain.
56. HYSTERANGIUM, Fitt.
Peridium indéhiscent, distinct, separable. Cavities at first
empty. Substance cartilagineo-glutinous. Spores minute.
1. H. nephriticnm, B. ; depressed, springing from a white,
flat, branched, membranous mycelium ; peridium firm, elastic,
distinct, tomentose ; substance pale blue or grey, here and
there greenish ; cavities radiating from the base ; spores minute,
oblong, pale clay-cojour.—Ann. Nat. Hist. xiii. p . 350.
Under trees. Clifton, C. E .B . Smell at first like that of
some Hypericum, then exactly that of a decaying Puff-ball.
The spores in the closely allied H. Pompholyæ, Tul., are rose-
coloured.
2. H. Thwaitesii, B. and Br. ; subglobose, white, rufous
when bruised ; peridium membranaceous ; spores oblong api-
culate.—Ann. of Nat. Hist. ser. 2. ii. p. 267.
Under trees. Bristol, C. E. B. Mycelium white, fibrillose.
Seldom flattened. Cavities brownish-olive. The liy-
.menium of Hysterangium is very like that of a young Phallus.
57. RHIZOPOGON, Tul.
Peridium continuous or cracked, adhering to creeping
' branched fibres, which traverse its surface. Cavities distinct,
at first empty. Spores smooth, oblong-elliptic.
I. R. rubescens, Tul. ; white, then reddish, and at length
livid-olive, furnished with a few fibrillæ ; substance very lacunose,
dirty-white, then olive ; cavities always empty.
In sandy fir-woods. Chudleigh, C. E. B. At first nearly
transparent, with white roots, and pink when touched. Smell
something like that of Melanogaster ambiguus when old,
when young like that of sour ham.
58. HYMENOGASTER, Tul.
Peridium fleshy or thin, running down into an absorbing
base. Cavities at first empty, radiating or irregular. Trama
composed of elongated cells, but not of byssoid flocci, and
therefore not easily separable. Spores various.
1. H. Klotzsohii, Tul.; ohovate, fibrillose at the base,
dirty-white, witliin dull rufous-ochre; spores small, elliptic,
obtuse at either extremity, nearly even.—Fl. Regn. Bor.

Amongst soil. Very rare. In the Glasgow Botanic Garden,
Klotzsch.
2. H. mutieus, B. and B r .; globose, quite white when
young, then tinged with brown and cracked, pale yellow-
brown within; spores obovate, oblong, very obtuse.—Ann. of

Under trees. Stapleton Grove, Bristol, C. E. B. Smell
very slight. Spores quite blunt.
3. H. luteus, V itt.; peridium very thin, soft and silky,
white, then brownish, bright yellow within; spores even,
ovate or elliptic, oblong, yellow.— Tul. t. \ . f . 3.
