em, quite wide, at length plane,
blackish or with varying tints of black.

The stem is three to four inches long, slender, firm, equal, hollow,
powdered above, whitish, sometimes tinged with red or yellow, slightly
striate at the top, as will be seen in the photograph with a glass,
generally stained with the spores.

The specimens in Figure 279 were found in a garden that had been
strongly manured. It is usually found on dung and on grassy lawns during
May and June. Captain McIlvaine in his book speaks of this mushroom
producing hilarity or a mild form of intoxication. I should advise
against its use.

_Anellaria. Karst._

Anellaria is from _anellus_, a little ring. This genus is so called
because of the presence of a ring on the stem.

The pileus is somewhat fleshy, smooth, and even. The gills are adnexed,
dark slate-colored, variegated with black spores. The stem is central,
smooth, firm, shining, ring persistent or forming a zone around the
stem.

_Anellaria separata. Karst._

Separata means separate or distinct.

The pileus is somewhat fleshy, bell-shaped, obtuse, even, viscid, at
first ochraceous, then dingy-white, shining, smooth, wrinkled when old.

The gills are firmly attached to the stem, broad, ventricose, thin,
crowded, clouded, cinereous, margin nearly white, slightly deliquescent.

The stem is long, straight, shining, white, thickened downward, ring
distant, top somewhat striate, bulbous at the base. The spores are
broadly elliptic-fusiform, black, opaque, 10x7u.

It is found on dung from May to October. It is not poisonous.

_Bolbitius. Fr._

Bolbitius is from a Greek word meaning cow-dung, referring to its place
of growth.

The pileus is membranaceous, yellow, becoming moist; gills moist but not
deliquescing, finally losing their color and becoming powdery; stem
hollow and confluent with the hymenophore. As the generic name implies
the plant usually grows on dung, but sometimes it is found growing on
leaves and where the ground had been manured the year before. The spores
are of a rusty-red color.

_Bolbitius fragilis. (L.) Fr._

Fragilis means fragile.

The pileus is membranaceous, yellow, then whitish, viscid, margin
striate, disk somewhat umbonate.

The gills are attenuated, adnexed, nearly free, ventricose, yellowish,
then pale cinnamon.

The stem is two to three inches long, naked, smooth, yellow. The spores
are rust-colored, 7x3.5, Massee. 14-15x8-9u. Saccardo.
