Campanulatus is from _campanula_, a little bell.
The pileus is an inch to an inch and a quarter broad, oval or bell-shaped, sometimes slightly umbonate, smooth, somewhat shining, grayish-brown, sometimes becoming reddish-tinted, the margin often fringed with fragments of the veil.
The gills are attached, not broad, ascending, variegated with gray and black.
The stem is three to five inches long, hollow, slender, firm, straight, often covered with frost-like bloom and often striate at the top, the veil remaining only a short time. The spores are subellipsoid, 8-9×6µ.
The gills do not deliquesce. It is widely distributed and is found in almost any horse pasture.
Captain McIlvaine says in his book that he has eaten it in small quantities, because larger could not be obtained, and with no other than pleasant effect. I have found it about Chillicothe quite frequently but have never eaten it. It is found from June to August.
Fimicolus is from fimus, dung; colo, to inhabit. The pileus somewhat fleshy, convex-bell-shaped, obtuse, smooth, opaque; marked near the margin with a narrow brown zone; the stem is fragile, elongated, equal, pallid, covered with frost-like bloom above; the gills are firmly attached to the stem, broad, variegated with gray and brown. _Fries._
The plant is very small and unimportant. It is found on dung, as its name indicates, from June to September. The caps appear lighter in color when dry than when wet.
Plate XLI. Figure 278.--Panaeolus solidipes.]
Solidipes is from solidus, solid; pes, foot; and is so called because the stem of the plant is solid. The pileus is two to three inches across; firm; at first hemispherical, then subcampanulate or convex; smooth; white; the cuticle at length breaking up into dingy-yellowish, rather large, angular scales. The gills are broad, slightly attached, whitish, becoming black. The stem is five to eight inches long and two to four lines thick, firm, smooth, white, solid, slightly striate at the top. The spores are very black with a bluish tint. _Peck._ 23d Rep. N. Y. State Bot.
This is a large and beautiful plant and easily distinguished because of its solid stem, growing on dung. Sometimes minute drops of moisture will be seen on the upper part of the stem. The plant is said to be one of the best of mushrooms to eat.
