TROPICAL POLYPORES 75 



1. FOMES ROSEUS (Alb. & Schw.) Cooke 



Pileus woody, dimidiate, varying from conchate to ungulate, 

 often imbricate and longitudinally effused, 2-4 X 6-30 X 0.5-3 

 cm.; surface rugose, subfasciate, slightly sulcate, rosy or flesh- 

 colored, becoming gray or black with age; margin acute, becoming 

 obtuse, sterile, pallid, often undulate; context floccose-fibrous to 

 corky, rose-colored, 0.2-2 cm. thick; tubes indistinctly stratose, 

 1-2 mm. long each season, mouths circular, 3-4 to a mm., edges 

 obtuse, concolorous; spores ellipsoid, smooth, thick-walled, 

 subhyaline, 3.5 X 6 ju. 



Found once at Jalapa, Mexico, and a few times in the Ber- 

 mudas; reported once from Cuba by Wright. It is easily con- 

 fused with F. Sagraeanus. 



2. FOMES SAGRAEANUS (Mont.) Murrill 



Pileus corky to woody, dimidiate, sessile, conchate or appla- 

 nate, often irregular, 4-6 X 5-10 X 0.5-2 cm. ; surface anoderm, 

 velvety, azonate, avellaneous, subsulcate, becoming glabrous, 

 brown or black, and horny-encrusted with age; margin thin, 

 concolorous; context corky, flesh-colored or light-brown, 1-3 mm. 

 thick; tubes indistinctly stratified, pale-rose-colored, 3-5 mm. 

 long each season, often found in one layer only, mouths circular, 



5 to a mm., edges obtuse, entire, roseous, becoming discolored 

 with age; spores globose, smooth, subhyaline or slightly smoky, 



6 |i. 



Frequent in many parts of the region on dead logs and stumps. 



3. FOMES TURBINATUS (Pat.) Murrill, comb. nov. 



Pileus usually conic, pendant, and vertically attached, but 

 sometimes dimidiate-sessile and ungulate, 1-2 cm. broad and 

 high; surface smooth or slightly sulcate, glabrous, pale-yellow 

 to brownish-yellow, margin entire, white; context thin, soft- 

 corky, pale-isabelline ; tubes very long, reaching I cm., not 

 distinctly stratified, isabelline within, mouths minute, con- 

 stricted, milk-white when young, the edges at first very obtuse; 

 spores globose, smooth, hyaline, 4-6 ju; conidia ovoid, smooth, 

 hyaline, 12-14 X 6-8 /*. 



This species was originally described from Venezuela, occurring 

 there on decayed branches. It has since been collected occa- 

 sionally in Guadeloupe ; at Castleton Gardens and Chester Vale, 

 Jamaica; and on dead limbs and decayed standing trunks in 

 western Cuba. It greatly resembles F. ohiensis in appearance 

 and habit, but has much longer, smaller tubes.
