MurRILL: POLYPORACEAE OF NORTH AMERICA 299 
Polyporus sclerodermeus Lév. Ann, Sc. Nat. Bot. III. 5: 129. 
1846. 
Polyporus marmoratus Berk. & Curt. Proc. Am. Acad. 4: 122. 
1858. : 
Fomes fasciatus Cooke, 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 Cedre/a and cocoa- 
nut logs. It replaces £. fomentaria in the south, but cannot be 
confused with it as some have supposed. 
3. Elfvingia reniformis (Morg.) 
Polyporus reniformis Morg. Jour. Cincinnati Soc. Nat. Hist. 8: 
103. 1885. 
Fomes reniformis Sacc. Syll. 6: 187. 1888. 
Collections examined: Ohio (Morgan), Kentucky (Miss 
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. zxcrassatus 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: “1 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. megaloma Lev. “ Again, 
the hymenial surface instead of being flat, is curved upwards in 
every case, this feature being well shown in the specimen sent.
