dead branches of Liriodendron and Juglans at Bethlehem, Penn- 

 sylvania : 



" P. longissime effusus, angustatus, albo-marginatus et effi- 

 guratus, margine tenui subfimbriato nec tamen byssino. Tubis 

 obliquis brevioribus, poris angustis, subflexuosis. Longitudine 

 4-6 unciali, y 2 -i unciali latitudine. Totus unicolor, eleganter 

 cinereus." 



There are no types, either at Philadelphia or at Kew, and no 

 one can say just what Schweinitz included under this name. 

 Morgan reports the species from Ohio and his specimens are 

 preserved (See P. Caryae). Ellis was probably influenced by 

 Morgan when he published his exsiccati. It is just possible, 

 though not probable, that P. cinerea and P. Caryae are synonyms, 

 but there is no way to prove it. 



6. Poria Caryae (Schw.) Cooke, Grevillea 14: in. 1886 



Polyporus Caryae Schw. Trans. Amer. Phil. Soc. 4: 159. 1832. 



Schweinitz found this species spreading a foot or more over a 

 fallen trunk of Carya alba at Nazareth, Pennsylvania. His de- 

 scription — an unusually long one for him — is as follows : 



" P. junior'*Tuberculoso-elevatus, interruptus, substantia spon- 

 giosa-tomentosa, margine sterili saepe tumido. Demum late 

 effusus, magis aequabilis et subindurescens, margine tunc tenuis- 

 simo, submembranaceo, candido, praeditus. Tubis brevibus, 

 parietibus crassiusculis, poris minoribus subrotundis et sub- 

 flexuosis ; interdum regulariter effusis, interdum pulvinatim .in 

 tuberculos elevatis. Ex fuliginis cinerascit. Ad pedalem longi- 

 tudinem sub trunco effusus." 



Fortunately, portions of the type are preserved, both at Phila- 

 delphia and at Kew, and they appear to match up perfectly with 

 what Morgan called P. cinereus Schw. and described as follows : 



" Widely effused, adnate, firm ; the border narrow, thin, white- 

 fimbriate. Pores small, unequal, subrotund, obtuse, cinereous. 



" In woods on the lower side of old logs ; common. The whole 

 of a uniform ashen hue except the minute whitish fringe of the 

 border. The growing specimens are somewhat moist, but they 

 shrink little in drying and become quite firm. The pores measure 

 about .20 mm. in diameter. It is an elegant species."
