same as they appear to be for T. sordidus-but more observations are
required to establish this. It is close to B. alutaceus, which is exactly the
position in which Peck placed it. The smoky buff pileus, reddish base of
the stipe with a red line at the apex, and lack of reticulation are the
main field characters. It may possibly have been confused with B. badius
as a yellowish brown variant. We have had such a bolete in the state,
and it does not react with NH40H in the same way as the red variant.
Smith 57612 from Tahquamenon Falls State Park appears to be
this species. It was mistaken for a slender specimen of B. badius.
165. Boletus albocarneus (Peck) Peck

Boletus chrysenteron var. albocarneus Peck, Bull. N. Y. State Mus. 54:185. 1901.
"Pileus 1-2.5 in. broad, convex, fleshy, dry, subglabrous, varying
from brick-red to bay-red, flesh white, sometimes tinged with red near
the surface, rarely rimulose. Tubes rather long, adnate or slightly depressed around the stem, greenish yellow, their mouths small, subrotund,
becoming blue to greenish blue when bruised. Stipe 1-2 in. long, 2-4
lines thick, equal or nearly so, solid, subglabrous, colored like or a little
paler than the pileus, white within. Taste pleasant."
Spores 12-15 X 4-5 /, smooth, lacking an apical pore, shape in
face view subfusoid to subelliptic, in profile obscurely to somewhat
inequilateral, color in KOH yellowish hyaline, in Melzer's merely yellowish, wall about 0.2 p thick.
Basidia 4-spored, 8-10 / broad, clavate, hyaline in KOH. Pleurocystidia 30-45 X 9-15 u, clavate to clavate-mucronate, content ochraceous in KOH and merely ochraceous-brown in Melzer's fading to ochraceous.
Pileus cutis a layer of interwoven hyphae 4-8 p wide, the end-cells
cylindric or weakly cystidioid (rarely over 11 p broad), cells elongate,
walls thin and smooth, content yellowish in KOH or Melzer's and not
rounding into globules. Some amyloid debris present in the layer.
Hyphae of the subcutis yellowish in Melzer's also. Clamp connections
absent.
Observations.-The type specimen gives one the impression that it
is the same as Tylopilus subpunctipes, but neither Peck's description nor
the microscopic data support this conclusion. It is close to B. badius but
smaller, and was described as having a dry pileus. We have had small
specimens of B. badius that might key out here. However, we need to
