The Mycologic Flora of the Miami Valley, 0. 197 



On trunks and bianclies of beech. Pileus 2-4 in. broad, stipe less 

 than an inch in length. Always known b^- its conchate form and 

 tough substance. It is not hirsute or villous like Lentinvs lecomtei. 



2. P. DEALBATUS, Berk. — Pileus coriaceous-soft, flabellitorm, some- 

 times lobed, umber, striate. Stipe lateral, rather long, compressed or 

 channeled, dilated above. Lamellse decurrent, distinct, umber. Spores 

 white. 



On branches of elm. Pileus ^-\ in. broad, the stipe an inch or less in 

 length. The pileus and stipe when dry are white and minutely 

 cracked, as if whitewashed; a dark border encircles the pileus, and the 

 lamellae are brown with a white edge. When moist the pileus is tough 

 and pliable, umber-brown and striate. Sometimes the stipe is forked, 

 and each division produces a pileus. There are few prettier fungi than 

 this. 



h. Lamellce determinate. 



3. P. STiPTicus, Bull. — Pileus coriaceous, reniform, cinnamon then 

 expallent; the cuticle seceding into furfuraceous scales. Stipe lateral, 

 short, dilated upward. Lamellae determinate, thin, close, reticulate- 

 connected, cinnamon. Spores white, .00J:6X-0025 mm. 



On stumps, trunks and branches, everywhere, very common, persist- 

 ing from autumn to spring. Pileus 1-1|- in. broad, stipe about ^ of an 

 inch long. Gregarious or caespitose; pileus semiorbicular, the margin 

 entire or lobed and involute. Taste styptic. This is distinguished 

 from Polyporus rhipidium b}^ its different hymenium. 



.4. P. FARiNACEDS, Schum. — Pilcus somewhat coriaceous, flexuous, 

 cinnamon-umber; the cuticle seceding into a whitish-lavender scurf 

 Stipe lateral, short, concolorous. Lamellae determinately free, distinct, 

 rather pale. Spores white. 



Upon trunks of hickory. Pileus f-l:^ in. broad, stipe about \ of an 

 inch long. The pileus is brown or blackish with a dense white 

 pubescence. What I have found grew out of the cracks in the 

 hickory bark. 



B. Pileus sessile or nearly so. 



5. P. ANGUSTATUS, Berk. — Pileus fleshy-coriaceous, thin, spatulate 

 or flabelliform, minutely pubescent, white, dirty white or yellowish. 

 Stipe extremel}' short or none. Lamellae very narrow, close, decurrent, 

 white or yellowish. Spores white. 



In woods on old logs, common. Pileus ^1^ in. long by ^1 in.
