flesh ; margin rounded; pores very minute, conve.x,
stratose, cinnamon, at first whitish.—Sow. t. 133.

as by other characters, it is clearly distinguished from P. fo-
mentarhis. Often resupinate.
43. P. Ribis, F r .; pileus corky, coriaceous, rather soft,
flattened, velvety, nearly even, ferruginous, tlien umber, tawny
within, as well as the sharp margin, and short, small, naked

the last, which also grows on willows. Both are frequently
resupinate. Crust black.
