99—COLLYBIA TENUIPHS. 
Pileus expanded, flat, very slightly viscid, smooth, yellowish- 
brown color, margin striate. Flesh yellow. Gills broad, pale yellow, 
rounded behind, strongly venosely connected. Stipe dark brown (almost 
black below, lighter brown above), minutely densely velvety, stuffed or 
hollow, tough, strongly cartilaginous. I find this plant about Cincinnati 
almost every season, usually in May or 
June. I have also seen it in the Cum¬ 
berland Mountains. Its features are 
the strict, tough, slender, velutinate 
stem, the yellow gills, and especially 
the strong venose connection between 
the gills. It usually grows somewhat 
gregarious on logs. It is closely re¬ 
lated to velutipes (more closely than 
generally supposed since a knowledge 
of the growing plant shows it to be 
very slightly viscid), but differs in its 
slender stem, its slight viscidity, and 
its mode of growth (hardly csespi- 
tose.) I have described the pileus as 
smooth, for though it has a velutinate 
appearance to the eye, well shown in 
our photograph, no hairs are shown 
even with the microscope on the speci¬ 
men at hand. I have such a strong 
impression, however, of having col¬ 
lected it with pileus velutinate that I 
suspect it varies in this regard.

Collybia tenuipes, (natural size.) 
This is one of the few American 
agarics named by Schweinitz. Peck 
has redescribed it from dried specimens 
under the name Collybia amabilipes. 
Prof. Morgan informs me it is the plant 
on which his record of Agaricus cerinus 
was based.

100—COFFYBIA STIPITARIA. 
Pileus expanded, plane, umbilicate, under a 
glass squamulose with appressed tawny hairs 
arranged somewhat in zones. Stipe slender, 
tough, dark brown, shaggy fibrillose. Gills 
white, separating free, broad (relatively), dis¬ 
tant (relatively.) 
It is liable to be taken for a Marasmius, as it 
has the Marasmius habit of reviving with moist¬ 
ure after having dried up. Its usual habitat is 
dead grass culms or twigs in woodland pastures.
