rinkles over the center of the cap. In size it agrees
with the smoky lactarius.

The =pileus= is convex, then plane, or somewhat depressed in the center,
dry, sometimes with a small umbo, dark brown or sooty (chocolate to seal
brown as given in Ridgeway's nomenclature of colors), covered with a
very fine tomentum which has the appearance of a bloom. The margin of
the cap, especially in old plants, is somewhat wavy or plicate as in
_Lactarius fuliginosus_. The =gills= are moderately crowded when young,
becoming distant in older plants, white, then cream color or yellow,
changing to reddish or salmon color where bruised. The =spores= are
yellowish in mass, faintly so under the microscope, globose, strongly
echinulate, 6--10 mu. The taste is mild, or sometimes slowly and slightly
acrid. The plants from North Carolina showed distinctly the change to
reddish or salmon color when the gills were bruised, and the taste was
noted as mild.

Blue Ridge Mountains, at Blowing Rock, N. C., September, 1899.

=Lactarius fuliginosus= Fr.--The smoky or dingy lactarius occurs in
woods and open grassy places. It is widely distributed. The plants are
4--7 cm. high, the cap 3--5 cm. broad, and the stem 6--10 mm. in
thickness. The light smoky color of the cap and stem, the dull yellowish
white color of the gills, and in old plants the wavy margin of the cap
make it comparatively easy to recognize the species.

The =pileus= is thin, at first firm, becoming soft, convex, then plane
and often somewhat depressed in the center, usually even, dry, the
margin in old plants crenately wavy, dull gray or smoky gray in color,
with a fine down or tomentum. The =gills= are adnate, distant, more so
in old plants, white, then yellowish, sometimes changing to salmon color
or reddish where bruised. The =spores= are yellowish in mass, faintly
yellow under the microscope, strongly echinulate or tuberculate,
globose, 6--10 mu. The =stem= is usually paler than the pileus, firm,
stuffed. The milk is white, slowly acrid to the taste.

Blowing Rock, N. C., during September, 1899.

=Lactarius gerardii= Pk.--This plant was described by Dr. Peck in the
26th Repo
