American plant Cooke referred it to P. oblectans, while Peck soon 

 discovered that P. splcndens was preoccupied by a Brazilian species 

 and changed the name to P. subsericius.

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. cinnamomea by its larger 

 size, more deeply depressed center and less shining surface. Speci- 

 mens have been examined for the principal herbaria and published
