299 MuRRiLL : Polyporaceae of North America 



Polyporus sclerodermciis Lev. Ann. Sc. Nat. Bot. III. 5 : 129. 



1846. 



Polyporus marmoratus Berk. & Curt. Proc. Am. Acad. 4 : 122. 



1858. 



Fomes fasciatus Codk&, Grevillea, 14: 21. 1885. 



Specimens examined : Ellis & Everhart, N. A. Fungi, no. 

 1702; Florida (Martin, Calkins, Rolfs, Lloyd, Rau), Louisiana 

 (Langlois), Alabama (Underwood, Earle, Baker), Texas (Egel- 

 ing), Jamaica (Earle). 



This plant is fairly abundant in tropical America, being known 

 from nearly all localities that have been explored. Earle found it 

 at three different points in Jamaica growing on Cedrela and cocoa- 

 nut logs. It replaces E. fomentaria in the south, but cannot be 

 confused with it as some have supposed.

 Price), Indiana (Underwood), Virginia (Murrill, Mrs. Murrill), 

 North Carolina (Memminger), Alabama (Underwood, Earle), 

 Louisiana (Langlois). 



When first sent to Kew this plant was determined as P. appla- 

 natus Pers., a closely allied European species. Later it was placed 

 by Cooke under P. incrassatus Berk., a plant indigenous to Aus- 

 tralia ! It may be said, however, that the specimens now at Kew 

 are not fairly representative even of the form and much less of the 

 habit of Morgan's species. The following extract from one of D. 

 L. James' letters written in 1882 refers to the peculiarities of P. 

 reniformis : " I am rather surprised at my fungus turning out to 

 be P. applanatus. It grows at the foot of old oak stumps and trees 

 and seems to be an annual, the previous year's growth being found 

 distinct and above the new growth in a decayed condition. The 

 pileus does not harden as in P. applanatus:' By P. applanatus is, 

 of course, meant our ordinary species, P. niegaloma Lev. " Again, 

 the hymenial surface instead of being flat, is curved upwards in 

 every case, this feature being well shown in the specimen sent.
