344 MurRILL: POLYPORACEAE OF NortTH AMERICA 
American plant Cooke referred it to P. odlectans, while Peck soon 
discovered that P. sp/endens was preoccupied by a Brazilian species 
and changed the name to P. sudsericeus.

This species appears to be common throughout the northern 
hemisphere in temperate regions, occurring in woods on dry ex- 
posed soil, especially where fires have been kindled, or rarely in 
moss or leaves. When young, it is ferruginous-cinnamon in color 
with punctiform tubes and thin substance; as it grows older the 
pileus becomes more depressed, the tubes longer and more decur- 
rent, the sterile marginal band disappears and the whole plant ap- 
pears thicker and firmer; in age the color becomes hoary, the 
zones are more marked, much of the tomentum disappears and the 
tubes and margin become more or less fimbriate. These changes 
often appear very marked when collections made in autumn are 
placed beside those of midsummer. 
The present species is at once distinguished from C. parvula 
by its much smaller tubes and from C. cixnamomea by its larger 
size, more deeply depressed center and less shining surface. Speci- 
mens have been examined for the principal herbaria and published
