Wet places and sphagnous mossy swamps. New York, Peck. Maine, Harvey. Peck, Boleti of the U.S.
Angora, West Philadelphia and Mt. Gretna, Pa. September. McIlvaine.
A few specimens found at Mt. Gretna had stems slightly reticulated. Its taste is sweet, smell mild, and cooked it is of excellent body and flavor.
B. deci´piens (B. and C.) Pk. Pileus dry, minutely silky, whitish-yellow or pale-buff, flesh buff, one-third in. thick; hymenium plane or somewhat concave, yellow, consisting of large, unequal, flexuous radiating tubes resembling multiseptate lamellæ. Stem equal, solid but spongy. Veil floccose, evanescent, adhering for a time to the margin of the pileus. Spores rather minute, oblong, ochraceo-ferruginous (rusty yellow), 8–10×3.5–4µ.
Pileus 2 in. broad. Stem 2–2.5 in. long, 3–4 lines thick.
Thin woods. North and South Carolina. M.A. Curtis.
Specimens of this species have not been seen by me. The authors remark that its affinities are clearly with Boletinus flavidus and its allies, from which it is distinguished by its large radiating pores. They also say that when dry it is scarcely distinguishable from Paxillus porosus Berk., except by its spores. This would imply that its stem is eccentric or lateral, and I have been informed by Mr. Ravenel that it is sometimes so. But specimens of this kind, labeled Boletinus decipiens B. and C., have been received, which show by their spores that they are Paxillus porosus. Besides, Professor Farlow informs me that authentic specimens of B. decipiens in the Curtisian Herbarium have only central stems, from which things I suspect that the two species have been confused. The spore dimensions here given are derived from a specimen in the Curtis Herbarium, through the kindness of Professor Farlow. Peck, Boleti of the U.S.
I have not recognized this Boletinus. Its affinities are with excellent edible species.
