Polyporaceae 



BOLETINUS PALUSTER. 



Natural size. (After Peck.) 



B. palus'ter Pk. Pileus thin, (Plate cxm.) Boietinns. 



broadly convex, plane or slightly 

 depressed, sometimes with a small 

 umbo, floccose-tomentose, bright red. 

 Tubes very large, slightly decurrent, 

 yellow, becoming ochraceous or dingy 

 ochraceous. Stem slender, solid, sub- 

 glabrous, red, yellowish at the top. 

 Spores pinkish-brown, 8-9x4^1. 



Pileus 1-2 in. broad. Stem 1-2 in. 

 long, 2-3 lines thick. 



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. Mcllvaine. 



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. (leci'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 lamellae. 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), 8-10x3.5-4^. 



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 eccen- 

 tric or lateral, and I have been informed by Mr. Ravenel that it is some- 

 times 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
