The Mycologic Flora of the Miami Valley^ O. 179 



5. C. ALBO-vioLACEDS,' Pers. — Pileus fleshy, silky with innate fibrils, 

 at length gibbous, violaceous-whitish. Stipe clavate, somewhat annu- 

 late, violaceous, whitish. Lamellag attached, rather distant, serrulate, 

 at first cinereous-violaceous. 



In woods. Pileus 2 3 in. broad, stipe 3 4 in. high. Inodorous, the 

 stipe being violet above and white below the obscure annulus, some- 

 times appears as if sheathed with a white silky covering; flesh juicy, 

 blue-white. 



Genus V. — Paxillus, Fr. 



Hymenophore contiguous with the stipe, decurrent. Lamellae mem- 

 branaceous, easily split, somewhat branched and anastomosing behind, 

 discrete from the hymenophore and easily separating from it. 



a. Pileus entire, the stipe central. 



1. P. FLAViDDS, Berk. — Pileus fleshy, plane then depressed, some- 

 what tomentose; the margin thin, involute, even or somewhat repand. 

 Stipe solid, tough, curved and crooked, tapering downward. Lamellae 

 long-decurrent, thin, sparingl}' branched, connected b}^ veins, bright 

 yellow. Spores sordid, somewhat fusiform, .010X.005 mm. 



On hillsides in woods. Pileus 2-3 in. across, stipe 1^-2 in. long. 

 Pileus reddish, brownish or alutaceous, more or less tomentose and 

 soft to the touch; stipe yellowish or reddish. This is one of Mr. Lea's 

 new species; it is quite common on the wooded bluff's about Cincin- 

 nati. It is readily known by its bright j^ellow decurrent lamellae, 



h. The stipe excentric or lateral. 



2. P. POROSUS, Berk. — Pileus flesh}^ excentric, irregular, somewhat 

 reniform, reddish or yellowish-brown, somewhat tomentose or glabrous. 

 Stipe short excentric or lateral, curved, more or less reticulated by the 

 decurrent pores. Hymenium bright 3^ellow, porous, formed by 

 numerous thin radiating folds which are crossed b}' other narrower 

 folds so as to form large angular pores. Spores bright j-ellow. 



On the ground in woods. Pileus 2-5 in. in diameter, a half to an 

 inch thick; stipe I^ in. or less in length. This is a very curious 

 species closel}' allied to Boletus. It is liable at the first glance at the 

 hymenium to be taken for a Boletus, but the pores are not easily 

 separable from each other. It has a ra<^her leathery feeling and 

 appearance though quite flesh}'. I have not observed the disagreeable 

 odor that Mr. Berkele}' speaks of. 



3. P. PANDOiDEs, Fr. — Pileus fleshy, dimidiate, conchate, downy
