in thickness. One side was reflexed about 1.5 cm. The surface of the 

 pileus in this case was minutely tomentose.

Trametes stereoides (Fries) Bres. (Plate III, fig. 14). 



Pilei imbricated, leathery, thin, stiff, effuso-reflexed, reniform, at 

 first tomentose, then glabrate, grayish-brown, with concolorous zones, 

 1 to 1.5 cm. long, 0.5 to 1 cm. broad. Pores short, quite large, obtuse, 

 variously formed, white. 



Trunks of conifers. 



This species seems to be quite abundant in the forests of Northern 

 "Wisconsin. Our specimens were collected in pine and mixed woods in 

 Oneida County, near Hazelhurst, at Shanagolden, Ashland County, 

 and in the Star Lake region. The specimens were found chiefly on 

 fallen hemlock or spruce branches and decayed logs. They were much 

 imbricated, effused and reflexed and laterally confluent, so that the 

 largest specimen measured about 12 cm. in length and 5 to 6 cm. in 

 breadth, being reflexed to about 2 to 3 centimenters. 



The pilei are thin, leathery but stiff; the surface very uneven, and 

 of a dark gray-brown. The zones are sometimes blackish, making the 

 surface look very much like that of Polystictus planus Pk., from 

 which, however, this species differs in its larger and coarser structure 

 and the larger pores. 



Fries (9) places the species in the genus Polyporus, but Bresadola 

 (in litt) calls it a Trametes and regards it as identical with T. mollis 

 Fries. 



This species is easily recognized by the very uneven, thin leathery 

 grayish-brown pileus and the large, shallow white pores which soon 

 tarn gray. 



Our specimens agree very well with Fig. 3, Taf. 187 of Fries Icones 

 II, page 86.

Trametes scutellata Schw. 



''Pileus pulvinate, narrow, zonate, yellowish- white, tomentose, but 

 at length laccate-glabrate, context thin, almost concolorous ; hymen- 

 ium concave, white; pores punctiform, dissepiments wide, rigid." 



This is another small whitish Trametes. The pileus is pulvinate, 

 hard corky; sometimes sc-utellate or even hoof-shaped with a narrow
