Figure 312.—Strobilomyces strobilaceus. Two-thirds natural size.
Strobilaceus, cone-like. This is especially emphasized from the fact that both the genus and the species are named from the fancied resemblance of the cap to a pine cone. It is ever readily recognized because of this character of the cap.
The pileus is convex, rough with dark umber scales drawn into regular cone-like points tipped with dark-brown; margin veiled, flesh grayish-white, turning red when bruised, and finally black.
Pore-surface grayish-white in young specimens, and usually covered with the veil; tubes attached to the stem, angular, turning red when bruised.
The stem is equal or tapering upward, furrowed at the top, covered with a woolly down. Spores dark-brown, 12–13×9µ. Found at Londonderry. Common in woods. August to September.
Boletinus. Kalchb.
Boletinus is a diminutive of Boletus.
Hymenium composed of broad radiating lamellæ, connected by very numerous and narrow anastomosing branches or partitions, forming large angular pores. Tubes somewhat tenacious, not easily separable from the hymenophore and from each other, adnate or subdecurrent, yellowish. Peck.
