f a
large size have been gathered in the fir woods near Mattapoisett,
Massachusetts. Cap 3 to 5 inches broad; stem 3 to 5 inches long. The
variety _immaculatus_ differs from the typical form in not becoming
spotted and in the broader gills, which are serrated.

FIGS. 7 to 9.--=Ag. (Collybia) velutipes= Curt. "_Velvet-Footed
Collybia_."

Cap fleshy, thin, at first convex, then plane, obtuse, smooth, viscid,
tawny or brownish yellow, turning dark; flesh yellowish and soft; gills
slightly adnexed, pale yellow; stem tough, stuffed, externally
cartilaginous, sometimes slender, but usually thick, covered with a
brown velvety down, dark bay color. This is a very common species in
some localities. It is densely caespitose, growing in heavy clusters on
old logs and tree trunks in parks, woods, and gardens. The plants are
quite gelatinous when cooked. Group figured from illustration by M. C.
Cooke.

Collybia _radicata_ Rehl. is recorded as an edible species. The plants
have a thin, slightly fleshy cap, slightly umbonate, wrinkled, and
glutinous at maturity; distant, white, adnexed gills, and tall, slender,
rigid stem. The latter is often twisted and usually attenuated upwards,
color pale brown. It has a long tapering root entering deeply into the
soil. This species is solitary in habit, and is commonly found in grass,
or near decayed stumps. Cap from 2 to 3 inches in diameter, stem 6
inches to 10 inches in length.

Collybia _esculenta_ Jacq., a small species found in pine woods as well
as in pastures in the spring, is recorded as edible by a number of
authors. In this species the cap is nearly plane, obtuse, and smooth,
brownish; gills adnate, whitish; stem very slender, fistulose, equal,
tough, smooth, reddish clay color, deeply rooting.

APPENDIX.

As Chief of the Division of Microscopy, U. S. Department of Agriculture,
the author prepared for the World's Columbian Exposition at Chicago a
collection of models of edible and poisonous mushrooms, for which a
medal and diploma were there awarded. The same collection, which now
belongs to the Museum of the Department of Agriculture, was exhibited at
the Atlanta Cotton Exposition in 1895, where a diploma was again awarded
for it, and has since been exhibited at the exposition of 1897 in
Nashville, Tenn. The models composing this collection, about one
thousand in number, were made from actual specimens and colored to
nature, the same species being generally r
