MurkILL ; PoLyPORACEAE OF NortH AMERICA 113. 
cultivated, in America in Alabama (Underwood), Colorado (Bethel, 
Cameron, Crandall), Kansas (Bartholomew, Cragin), Missouri (?), 
Nebraska (Webber), Ohio (Lloyd), Tennessee (Schrenk). 
This fungus is very uniform in habit and appearance both in 
Europe and America, where it occurs on various species of Prunus 
and its near allies. Although confused in literature with Poly- 
porus igniarius L.., it is very distinct and always easily recognized. 
In an orchard near Mauritzberg, Sweden, where P. igniarius was 
abundant on apple trees, P. fu/vus was confined to the stumps and 
dead or dying trunks and branches of plum trees. 
3. Pyropolyporus crustosus sp. nov. 
An ungulate plant of medium size with brown tubes, ferrugi- 
nous substance and smooth encrusted dark brown surface. Pileus 
woody, convex above, plane below, somewhat compressed ungu- 
late, 7 12 § cm.; surface glabrous, horny encrusted, dark brown, 
concentrically sulcate, marked with narrow black concentric lines ; 
Margin rounded, yellowish brown, sterile: context hard, concen- 
trically banded, ferruginous, 2 cm. thick behind ; tubes indistinctly 
stratified, o.5—1 cm. long each season, 5-6 to a mm., drab-colored 
within, mouths polygonal, concolorous, edges thin, acute, entire : 
spores globose to ovoid, smooth, thin-walled, hyaline, 3.5-4 4 +, 
hyphae darker, cystidia none. 
Collected by Earle on a standing tree trunk at an altitude of 
4,000 feet on Rose Hill, Jamaica, October, 1902. 
4. Pyropolyporus Calkinsii sp. nov. 
A large ungulate fungus glabrous and furrowed above and 
uniformly hard and fulvous within. Pileus very hard woody 
throughout, ungulate, 10 X 10 X 10 cm.; surface glabrous, dark 
brown to black, marked with rather shallow concentric furrows, 
crust thin, horny, never rimose; margin rounded, concolorous 
with the hymenium: context very hard woody, fulvous, I cm. 
thick ; tubes in many indistinct layers, slender, minute, 7 to a 
mm., fulvous, mouths nearly circular, obtuse, entire: spores 
ovoid, hyaline, with thick, smooth, pale ferruginous wall, 3-5 X 
5-7 #, hyphae ferruginous, cystidia none. 
This species occurs on living trees of live-oak in Florida, where 
it was collected in considerable quantity by Major Ww. W. Calkins 
during the winters of 1886 and 1887. Several specimens are in 
the herbarium of the New York Botanical Garden and a single
