The Mycologio Flora of the Miami Valley^ 0. 199 



coriaceous, obsoletely zonate, tomentose, pallid. Lamellae straight, 

 somewhat branched, aoastomosing, sordid white. 



On stumps and logs in autumn, persisting till the following spring. 

 Common. Pileus 2-4 in. broad, projecting 1-2 in. Solitary or often much 

 imbricated and confluent; the pileus deeply and concentrically grooved, 

 clothed with dense pubescence or coarse velvet)^ down, grayish, j'ellow- 

 ish or brownish, sometimes with distinct colored zones, often green 

 with minute Algae. Lamellae at first thick, somewhat porose, sordid; 

 afterward thinner, the edge acute becoming yellowish. 



2. L. viALis, Peck. — Pileus coriaceous, sessile dimidiate, obscurely 

 zonate, somewhat tomentose, brown or grayish-brown, the margin 

 cinereous. Lamellae thin, abundantl}' anastomosing, pallid, cinereous- 

 pruinose on the edge. 



Very common on railroad ties. Pileus 13 in. in breadth, projecting 

 nearly an inch. Often much imbricated and confluent. The plants 

 are commonly much blackened by the grease and dirt of the passing 

 trains. I have a suspicion that this fungus is not diflE"erent from 

 Doedalea palUdo-fulva, Berk. 



3. L. s.ffiPiARiA, Schaeff. — Pileus dimidiate, sessile, coriaceous, hard, 

 zonate, strigose-tomentose, rough, bright-brown; the margin yellowish. 

 Lamellae rather thick, branched, anastomosing, yellowish. 



This plant which properly grows on pine wood, I have only seen on 

 white poplar stumps. Pileus 1-3 in. broad, projecting nearlj' an 

 inch. Often confluent, deeply zoned; substance coriaceous, fibrous, of 

 a fine ocher or rhubarb color. Hymeninm composed of brownish 

 plates, tolerabl}" regular, but here and there slightly branched. 



Note. — Lenzites cookei, Berk., and L. cratcegi, Berk., which are 

 found in this region, are considered by Prof. Chas. H. Peck to be only 

 forms of the Protean species Doidalea confragosa, Bolt. To this 

 opinion, from my own observation, I am willing to subscribe, 1 have 

 in my possession, of ra v own collecting, forms representing the three 

 genera, Lenzites, Trametes, and Dcedalea.
