only; colored like the pileus or a little
paler, sometimes slightly furfuraceous. Spores subfusiform,
brownish-ochraceous. _Peck_, Boleti of U. S.

The specimens in Figure 299 were found at Londonderry, about fifteen
miles east of Chillicothe, in a grassy woods near a stream. The taste is
agreeable when raw and quite good when cooked. This might appropriately
have been called the lilac Boletus, for that shade of color is usually
present in it, somewhere. August to October.

_Boletus auripes. Pk._

YELLOW-STEMMED BOLETUS. EDIBLE.

[Illustration: Figure 300.--Boletus auripes. One-half natural size. Caps
yellowish-brown. Tube surface and stem yellow.]

Auripes is from _aureus_, yellow or golden; _pes_, foot; so called from
its yellow stem.

The pileus is three to four inches broad, convex, nearly smooth,
yellowish-brown, the flesh often cracking in areas in old plants; flesh
yellow at first, fading to a lighter color, in age.

The tubes are nearly plane, their mouths small, nearly round, at first
stuffed, yellow.

The stem is two to four inches long, nearly equal, often reticulated,
solid, a bright yellow on the surface and a light yellow within. The
spores are ochraceous-brown, tinged with green, 12x5u.

The whole plant, except the upper surface of the cap, is a golden
yellow, and even the surface of the cap is more or less yellow. It
favors one form of the B. edulis. It is sometimes found in mixed woods,
especially if there are mountain laurels in the woods (_Kalmia
latifolia_). It is found in July and August.

_Boletus retipes. B. and C._

THE BEAUTIFUL-STEMMED BOLETUS. EDIBLE.

[Illustration: Figure 301.--Boletus retipes. Natural size.]

Retipes is from _rete_, a net; _pes_, a foot; so called from the
delicate net-work seen on the stem.

The pileus is convex, dry, powdered with yellow, sometimes rivulose or
cracked in areas. The tubes are adnate, yellow.

The stem is subequal, cespitose, reticulate to the base, pulverulent
below. The spores are greenish-ochraceous, 12-15x4-5u. _Peck_, Boleti.

B. retipes is very close to B. ornatipes, but its manner of growth, its
pulverulent cap, and its greenish-ochraceous spores will at once
distinguish it. I have found them on Ralston's Run, a number from the
same mycelial cluster, as in Figure 301. The caps only are good. The
specimens in the figure were found near Ashville, N. C., and
photographed by Prof. H. C. Beardslee.
