Polyporus admirabilis Pk, 



Wood of appletrees. Lake George Mrs R. B. VanAlstyne. The 

 specimen here recorded is less regular and less deeply depressed in the 

 center than the typical form, which was found growing from the base of 

 an appletree in Maine. 



Fomes roseus {A. ^ S.) Fr. 



Decaying trunks and wood of spruce. Indian pass and Floodwood. 

 The pores have nearly the same color and size as the pores of F. 

 c a rn e u s , and the young pileus and newly grown margin also resemble 

 those of F. carneus in color, but in shape the pileus is different. It 

 is thicker, triquetrous or ungulate, not imbricate nor laterally confluent, 

 the surface is more even and covered with a corneous crust after the first 

 year. The pileus becomes blackish or cinereous and is somewhat marked 

 by concentric furrows or depressions showing the limits of the yearly in- 

 crements. The substance is similar to that 'of F. carneus, but the 

 color of it is slightly paler.
