2. I. LACTEUS, Fr. Pileus effuso-reflexed, coiaiceous, \ilIous, 

 concentricaliy sulcate, white, teeth < lose, seriately arranged, acute, 

 more or less incised, white. 



On trunks of Oak, rare. Pileus, nearly an inch in width and 

 projecting about half an inch, but the pilei are usually more or less 

 confluent. The teeth are short, denticulate, and often with a con- 

 centric rather than a lamellate arrangement. 



3. I. TULiPiFER^, Schw. Pileus very extensively effused, 

 shortly reflexed, villous, azonate, while. Teeth porose, connected 

 at the base, irregular, denticulate and incised, white. 



On trunks and branchesiof Liriodendron, Hickory, etc , very 

 common. By far the greater part resupinate, with a long and 

 narrow reflexed margin, often on both edges. It remains a long 

 tmie porose, the dentate dissepiments finally lengthen inio 

 flat irregular teeth. It was first described by Fries as a Polyporus, 

 and this is what it should have been allowed to remain. 



II. Resupinati. Pileus none ; wholly resupinate. 



4. I. FUSCESCENS, Schw. Coriaceous membranaceous, olivace 

 ous then cervine, at first orbicular, then confluent and extensively 

 effused, with a narrow fimbriate border. Teeth irregular, unequal, 

 compressed, setulose, cervine. 



On dry Oak branches; very common. Effused along the under 

 side of a branch sometimes for several feet. The hymenium is 

 si-nuose-plicate, the folds broken into very unequal and irregular 

 teeth, varying from narrow and pointed to broad, flat, and even 

 sinuous; it is invested with minute brownish bristles; these are the 

 "ascisprominulis fuscis", of Schweinitz's description ; they are of the 

 same nature as those which occur in some species of Stereum 

 (Hymenochsete). Old weathered specimens became cinnamon or 

 brownish, and these are said to be /. einnamof neons, Fr. 



5. I. LABTicoLOR. B. and C. Memljranaceous, separable, 

 widely effused, the border byssine, white. Teeth compressed, 

 dentate and lacerate at the apex, seriately arranged, reddish o( lira 

 ceous. 



On dry Elm branches, rare. Effused for several inches on the 

 under side, and more or less separable, with a white subiculum and 

 a white byssine margin. The teeth are thin, flat, and coriac eous, 

 and it seems to me best recognized as an Irpex. It is //vJ/ni/n
