tinarius is so called because of the cinnamon color of the entire
plant, especially of the cap and stem. It grows in the woods during
summer and autumn. It is a very pretty plant, and varies from 5--8 cm.
high, the cap from 2--10 cm. broad, and the stem 4--6 mm. in thickness.

The =pileus= is conic, or convex, and nearly expanded, sometimes nearly
plane, and again with a prominent blunt or conic umbo. Sometimes the
pileus is abruptly bent downward near the margin as shown in the plants
in Fig. 155, giving the appearance of a "hip-roof." The surface is
smooth, silky, with innate fibrils. Sometimes there are cinnabar stains
on parts of the pileus, and often there are concentric rows of scales
near the margin. The flesh is light yellowish and with stains of
cinnabar. The =gills= are adnate, slightly sinuate, and decurrent by a
tooth, easily separating from the stem, rather crowded, slightly
ventricose. The color of the gills varies greatly; sometimes they are
the same color as the pileus, sometimes reddish brown, sometimes blood
red color, etc. This latter form is a very pretty plant, and is var.

Figure 155 is from plants (No. 2883 C. U. herbarium) collected at
Ithaca. The species is widely distributed in this country as well as in
Europe.

=Cortinarius (Dermocybe) ochroleucus= (Schaeff.) Fr.--This is a very
beautiful plant because of the soft, silky appearance of the surface of
pileus and stem, and the delicate yellowish white color. It occurs in
woods, on the ground among decaying leaves. The plants are 4--12 cm.
high, the cap 4--7 cm. broad, and the stem above is 6--10 mm. in
thickness, and below from 2--3 cm. in thickness.

same as in Figure 156, this represents older plants.]

The =pileus= is convex to nearly expanded, and sometimes a little
depressed, usually, however, remaining convex at the top. It is dry, on
the center finely tomentose to minutely squamulose, sometimes the scales
splitting up into concentric rows around the cap. The cap is fleshy at
the center, and thin at the margin, the color is from cream buff to
buff, d
