Polyportis chioneus Fr. Common on birch logs and on fallen or 

 dead limbs. P. a 1 b e 1 1 u s Pk. is considered the same by some 

 authors. Lloyd says it is not the true P. chioneus of Fries. 



Polyporus circinatus Fr. Under spruce and balsam, on the 

 ground; sometimes intergrown with Lycopodium among which it 

 may be growing. The pileus is rarely 15 cm broad, more commonly 

 smaller. 



Polyporus elegans Fr. On decaying logs. 



Polyporus galactinus Berk. On logs and fallen branches of spruce 

 and on sticks of other wood. This was at first thought to be 

 P. b o r e a 1 i s , but that species was not discovered in this locality. 



Polyporus gilvus Fr. On an alder trunk. 



Polyporus glomeratus Pk. On log of some deciduous tree. The 

 greenish color when fresh is distinctive. It is at first resupinate and 

 widely spread and when dry may be passed over as a young 

 P. a d u s t u s ; the greenish color disappears. 



Polyporus guttulatus Pk. On some conifer logs and a white pine 

 stump. 



Polyporus intybaceus Fr. On stump of tamarack tree. The spores 

 measure 5-6 by 2-3 microns. The specimen had only three pileoli, 

 each 3-5 inches broad, on an extended, connate stipe about 5 inches 

 long. According to Saccardo it is normally very much branched 

 with numerous pilei. 



Polyporus nidulans Fr. On wood, probably maple. Infrequent. 



Polyporus picipes Fr. Common on decaying logs. 



Polyporus pubescens Fr. Common on birch, willow, alder etc. 



Polyporus radiatus Fr. On birch; frequent. The pore surface of 

 the fresh plant is mostly smoky gray (Ridg.). Pileus sometimes 

 with a golden yellow margin. P. aureonitens Pat. et Pk. is 

 probably the same, as the colors vary considerably even on the same 

 branch. 



Polyporus schweinitzii Fr. On white pine and spruce logs and 

 stumps. Frequent. 



Polyporus spumeus Fr. On ash logs. This white species is re- 

 duced to a small size when dried and then becomes dingy yellowish 

 brown. 



Polyporus sulphurens Fr. On trunks and logs of deciduous trees. 



Polyporus weinmanni Fr. On decaying conifer logs. 



Polystictus hirsutus Fr. On dead wood of deciduous trees. 



Polystictus perennis Fr. In open ground or clearings. 



iPolystictus velutinus Fr. On dead beech limbs. Much like 

 P. pubescens, but thinner, more zonate, not so radiately
