CLASSIFICATION OP AH IRICS 



Caespitose, often imbricate, Bometimes solitary, on ven rotten 

 wood of birch, hemlock, etc., <»r northern Michigan. Baj View, 

 Houghton, Negaunee. Julj August. Infrequent. Probably edible. 



This species has much the appearance of l'i< urotus p< taloidi s and 

 Pleurotus (ilhohniiiius. When fresh 11 is hard i«i tell whether ii 

 ought in be ceferred to Panus or Pleurotus. I have found ii only in 

 the region of conifer or ini.\<'<l woods.

"PILEUS 8-12 mm. broad_, firm, thin, convex, deflexed or Bubpen 

 (hint. hygrophanous } minutely farinaceus-tomentose, pinkish-gray. 

 GILLS moderately broad and close, converging t<> an eccentric 

 point, '/"//,■ ferruginous. STEM very shorl below or obsolete, obli- 

 quely attached i<> the vertex of the pileus." 



"Gregarious. Trunks df (lend willows."

 of Science. I have given Peck's description.

Tough, even somewhat woody in age, Lignicolous and polymorph 

 ous. They approach the fleshy Pleuroti on one side, and the woodj 

 Lenzites mi the other. From Panus tin- thin, lacerate edge of the 

 ^•ills alone distinguishes them. They are very abundant in the 

 tropics inn there are relatively few species with as. 



The PILEUS varies in size, being quite large in /-. lepideiis and 

 /.. rul/iintis, or only about a centimeter broad in our small forms. 

 It is often scaly spotted, by the breaking up of'the cuticle. Tin. 

 GILLS are thin ;is compared with our species of Panus, and be 

 come lacerated-serrate on the edge. Their texture is homogeneous 

 with the trama of the pileus and ao1 a1 ;ill separable from it. at

 decurrent or become so at maturity. Tin- STEM is tough, ol
