Detroit. A number of this species form a prize for the table.

_Cortinarius Atkinsonianus. Kauff._

[Illustration: Figure 244.--Cortinarius Atkinsonianus. Caps waxy-yellow,
bulbous stem, spider-like veil.]

Atkinsonianus is named in honor of Prof. Geo. F. Atkinson.

The pileus is 8 cm. broad, expanded, _wax-yellow_ or _gallstone-yellow_
to _clay-colored and tawny_ (Ridg.), colors very striking and sometimes
several present at once; viscid, smooth, even, somewhat shining when
dry. Flesh thick, except at margin, bluish-white like the stem, or
paler, scarcely or not at all changing when bruised.

The gills are comparatively narrow, 6-8 mm., width uniform except near
outer end, adnate, becoming slightly sinuate, _purplish_ to yellow, then
cinnamon.

The stem is _violaceus-blue_, 8 cm. long, 12-15 mm. thick, equal or
slightly tapering upward, bulbous by a rather thick, marginate bulb 3
cm. thick, hung with fibrillose threads of the universal veil, which is
a beautiful pale-yellow and clothes the bulb even at maturity;
violaceous-blue within, solid. Spores 13-15ux7-8.5u, _very
tubercular_. _Kauff._

The specimens in Figure 244 were found in Poke Hollow near Chillicothe.
I have found them on several occasions. They are edible and of very good
flavor. Found from September to frost. The specimens illustrate the
spider-like veil that gives rise to the genus.

_Cortinarius umidicola. Kauff._

[Illustration: Figure 245.--Cortinarius umidicola. One-half natural
size. Caps pinkish-buff.]

Umidicola means dwelling in moist places. Pileus as much as 16 cm. broad
(generally 6-7 cm. when expanded), hemispherical, then convex and
expanded, with the margin for a long time markedly incurved; young cap
heliotrope-purplish with umber on disk, or somewhat fawn-colored, fading
very quickly to pinkish-buff, in which condition it is usually found;
margin when young with narrow strips of silky fibrils from the
universal veil; pileus when old covered with innate, whitish, silky
fibrils, hygrophanous; surface punctuate, even when young. Flesh of stem
and pileus lavender when young but soon fading to a sordid white, thick
on disk, abruptly thin towards margin, soon cavernous from grubs. The
gills are very broad, as much as 2 cm.; at first lavender, soon very
pale-tan to cinnamon; rather distant, thick, emarginate w
