The Mycologic Flora of the Miami Valley, O. 197 
On trunks and branches of beech. Pileus 2-4 in. broad, stipe less 
than an inch in length. Always known by its conchate form’ and 
tough substance. It is not hirsute or villous like Lentinus lecomtei. 
2. P. pEAaLBatus, Berk.—Pileus coriaceous-soft, flabelliform, some- 
times lobed, umber, striate. Stipe lateral, rather long, compressed or 
channeled, dilated above. Lamelle decurrent, distinct, umber. Spores 
white. 
On branches of elm. Pileus 3-1 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 
lamelle 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. 
b. Lamelle determinate, 
3. P, stipticus, Bull.—Pileus coriaceous, reniform, cinnamon then 
expallent; the cuticle seceding into furfuraceous scales. Stipe lateral, 
short, dilated upward. Lamelle determinate, thin, close, reticulate- 
connected, cinnamon. Spores white, .0046.0025 mm. 
On stumps, trunks and branches, everywhere, very common, persist- 
ing from autumn to spring. Pileus 1-14 in. broad, stipe about i of an 
inch long. Gregarious or cespitose; pileus semiorbicular, the margin 
entire or lobed and involute. Taste styptic. This is distinguished 
from Polyporus rhipidium by its different hymenium. 
4, P. FaRINACEUS, Schum.—-Pileus somewhat coriaceous, flexuous, 
cinnamon-umber; the cuticle seceding into a whitish-lavender scurf. 
Stipe lateral, short, concolorous. Lamellze determinately free, distinct, 
rather pale. Spores white. 
Upon trunks of hickory. Pileus 3-14 in. broad, stipe about + of an 
inch long. The pileus is brown or blackish with a ene white 
pubescence. What I have found grew out of the cracks in the 
hickory bark. 
B. Pileus sessile or nearly so. 
5. P. ancustatus, Berk.—Pileus fleshy-coriaceous, thin, spatulate 
or flabelliform, minutely pubescent, white, dirty white or yellowish. 
Stipe extremely short or none. Lamelle very narrow, close, decurrent, 
white or yellowish. Spores white. 
In woods on old logs, common. Pileus 3-14 in. lopg by 4-1 in.
