_Hypholoma. Fr._

Hypholoma is from two Greek words, meaning a web and a fringe, referring
to the web-like veil which frequently adheres to the margin of the cap,
not forming a ring on the stem and not always apparent on old specimens.

The pileus is fleshy, margin at first incurved. The gills are attached
to the stem, sometimes notched at the stem. The stem is fleshy, similar
in substance to the cap.

They grow mostly in thick clusters on wood either above or under the
ground. The spores are brown-purple, almost black.

This genus differs from the genus Agaricus from the fact that its gills
are attached to the stem and its stem is destitute of a ring.

_Hypholoma incertum. Pk._

THE UNCERTAIN HYPHOLOMA. EDIBLE.

Plate XXXVII. Figure 262.--Hypholoma incertum.]

Incertum, uncertain. Prof. Peck, who named this species, was uncertain
whether it was not a form of H. candolleanum, to which it seemed to be
very closely related; but as the gills of that plant are at first
violaceous and of this one white at first, he concluded to risk the
uncertainty on a new species.

The pileus is thin, ovate, broadly spreading, fragile, whitish, margin
often wavy and often adorned with fragments of the woolly white veil,
opaque when dry, transparent when moist.

The gills are thin, narrow, close, fastened to the stem at their inner
extremity, white at first, then purplish-brown, edges often uneven.

The stem is equal, straight, hollow, white, slender, at least one to
three inches long. The spores are purplish-brown and elliptical. It is
found in lawns, gardens, pastures, and thin woods. It is small but grows
in such profusion that one can obtain quantities of it. The caps are
very tender and delicious. It appears as early as May.

_Hypholoma appendiculatum. Bull._

THE APPENDICULATE HYPHOLOMA. EDIBLE.

Appendiculatum, a small appendage. This is so called from the fragments
of the veil adhering to the margin of the cap.

The pileus is thin, ovate, expanded, watery, when dry, covered with dry
atoms; margin thin and often split, with a white veil; the color when
moist dark-brown, when dry nearly white, often with floccose scales on
the cap.

The gills are firmly attached to the stem, crowded, white, then
rosy-brown, and at length dingy-brown.

The stem is hollow, smooth, equal, white, fibrous, m
