ost soft, glutinous, at first concealing the
tubes, then collapsing and forming a narrow whitish or brownish band
around the stem. Our Boletus had a brownish ring. The cap was covered
with a sticky, skin-like layer, called the pellicle or cuticle, both
terms having the same meaning.

+BOLETUS AFFINIS = related.+
+The Related Boletus.+

+Cap+ reddish-brown, fading to yellow, 2 to 4 inches broad, convex above
and almost plane, nearly smooth, flesh white. +Tubes+ plane or convex,
adnate or slightly compressed around the stem, at first white and
stuffed, then yellowish, turning to rusty ochraceous when wounded.
+Stem+ 1 1/2 to 3 inches long, 4 to 8 lines thick, nearly equal, even,
smooth, paler than the cap. Our specimen had a few yellowish spots on
the cap, and is called Var. maculosus. (Edible.)

+PAXILLUS LEPTOPUS = thin and a foot.+
+The Thin-stemmed Paxillus.+

This is the only specimen of the genus Paxillus that we have found.
There is another species, P. involutus, which Professor Peck says is
edible. Stevenson says that P. leptopus is a remarkable species, that it
is distinguished from P. involutus by having the gills simple at the
base, not united by interlacing or transverse veins (anastomosing).
+Cap+ was a light brownish-yellow; it varies from 1 1/2 to 3 inches in
breadth, eccentric or lateral, depressed in the middle, dry, covered
with dense down, soon torn into scales, which are a dingy yellow. Flesh
yellow. +Stem+ short, scarcely 1 inch, tapering downward, yellow inside.
+Gills+ decurrent, tense and straight, crowded, narrow, yellowish, then
darker in color. It was growing on the ground in September.

+CORTINARIUS ALBO-VIOLACEOUS = white and violet.+
+The Violet-colored Cortinarius.+

+Cap+ whitish-violet, 2 to 3 inches broad, fleshy, convex, broadly
umbonate or gibbous, dry, beautifully silky and becoming even; flesh
juicy, a bluish-white color. +Stem+ 2 to 4 inches long, solid, firm,
bulbous, club-shaped, 1/2 to 1 inch thick. It is, both outside and inside,
of a whitish violet color, often fibrillose above, with the cortina, and
sometimes with the white veil, in the form of a zone at the middle.
+Gills+ adnate, 2 to 3 lines broad, somewhat distant, slightly
serrulated, of a peculiar ashy violaceous color, at length sl
