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 ancF appearance both in 

 Europe and America, where it occurs on various species of Pritnus 

 and its near allies. Although confused in literature with Poly- 

 porus igtiiarius L., it is very distinct and always easily recognized. 

 In an orchard near Mauritzberg, Sweden, where /'. igniarius was 

 abundant on apple trees, P. fulviis 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, 7X 12X5 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, 0.5-1 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, 3.5-4X4/^, 

 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 h\-menium : 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 11., hyphae ferruginous, cystidia none. 



This species occurs on living trees of live-oak in Florida, where 

 it was collected in'considerable quantity by Major W. W. Calkins 

 during the winters of 1886 and 1887. Several specimens are in 

 the herbarium of the New York Botanical Garden and a single
