Figure 314.—Boletinus cavipes.
Cavipes is from two Latin words meaning a hollow stem.
The pileus is broadly convex, rather tough, flexible, soft, subumbonate, fibrillose-scaly, tawny-brown, sometimes tinged with reddish or purplish, flesh yellowish. The tubes are slightly decurrent, at first pale-yellow, then darker and tinged with green, becoming dingy-ochraceous with age. The stem is equal or slightly tapering upward, somewhat fibrillose or floccose, slightly ringed, hollow, tawny-brown or yellowish-brown, yellowish at the top and marked by the decurrent dissepiments of the tubes, white within. Veil whitish, partly adhering to the margin of the pileus, soon disappearing. The spores are 8–10×4µ. Peck, in Boleti of the U. S.
This plant grows in New York and the New England states, under pine and tamarack trees. The caps are convex, covered with a tawny-brown fibrillose tomentum. The stems of those I have seen are hollow from the first. The plants in Figure 314 were sent me from Massachusetts by Mrs. Blackford.
Boletinus porosus. (Berk.) Pk.
Figure 315.—Boletinus porosus. Two-thirds natural size. Caps nut-brown, yellowish-brown or olivaceous.
These form a small but interesting species, not usually exceeding three and a half inches in diameter nor more than two inches in height.
