Figure 299.—Boletus separans. One-half natural size.
Separans, separating, alluding to the tubes sometimes separating from the stem by the expansion of the pileus.
The pileus is convex, thick, smooth, subshining, often pitted or corrugated; brownish-red or dull-lilac, sometimes fading to yellowish on the margin; flesh white and unchangeable.
Tubes at first are nearly plane, adnate, white and stuffed, then convex, depressed around the stem, ochraceous-yellow or brownish-yellow and sometimes separating from the stem by the expansion of the pileus.
The stem is equal or slightly tapering upward; reticulated, either wholly or in upper part 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.
