10. FULVIFOMES EXTENSUS (Lev.) Murrill, comb. nov. 



Pileus corky to woody, dimidiate to flabelliform, applanate, 

 10-20 X 15-30 X 1-3 cm.; surface velvety, thinly encrusted, 

 rugose, zonate, sulcate, fulvous to castaneous, becoming dark 

 and rimose with age; margin thin, acute to subobtuse, sterile, 

 velvety, isabelline to fulvous, undulate to lobed; context corky 

 to woody, yellow, slightly zonate, becoming darker, with dendroid 

 markings, in age, 0.5-1 cm. thick; tubes evenly and distinctly 

 stratified, 2-4 mm. long each season, fulvous, mouths circular, 

 minute, 5 to a mm., edges obtuse, entire, ochraceous to fulvous; 

 spores globose, smooth, fulvous, 4-5 ju; cystidia few, ventricose, 

 fulvous, about 15 X 7 /*. 



Common throughout on decayed trunks of various trees. The 

 type at Paris from Guadeloupe is well preserved, although the 

 color of the context is not quite so bright as in fresh specimens. 



ii. FULVIFOMES SUBLINTEUS Murrill, comb. nov. 



Pileus corky to soft-woody, dimidiate, applanate, 6-8 X 7-10 

 X 1-2 cm.; surface finely tomentose to glabrous, very thinly 

 encrusted, smooth, almost free from markings of any kind, 

 light-bay to almost black; margin thin, rarely lobed, tomentose, 

 ferruginous; context corky, slightly zonate, melleous, 3-10 mm. 

 thick; tubes distinctly stratified, separated by layers of context, 

 2-6 mm. long each season, umbrinous within, mouths subcircular, 

 7 to a mm., edges thin, entire, becoming umbrinous; spores 

 globose, smooth, brown, 5ju; cystidia none. 



Found once on decayed wood of mesquite at Tepolobampo, 

 Mexico. 



12. FULVIFOMES HYDROPHILUS Murrill, comb. nov. 



Pileus small, woody, ungulate, usually laterally attached, 

 2-3 X 2-4.5 X 2-3.5 cm.; surface uneven, rugose, many times 

 sulcate, bay to chestnut with fuliginous lines, finely tomentose to 

 nearly glabrous, horny-encrusted; margin subobtuse, melleous, 

 entire; context scarcely I cm. thick, woody-punky, deep-fer- 

 ruginous to fulvous ; hymenium glistening, melleous when looked 

 at from the side, olivaceous-umbrinous when viewed perpendicu- 

 larly; tubes indistinctly stratified, fulvous with a grayish tint, 

 2-3 mm. long each season, mouths circular, 4-5 to a mm., edges 

 obtuse, entire; spores subglobose, smooth, fulvous, uniguttulate, 

 copious, thick-walled, 3.5-4.5 ^; cystidia none. 



Collected twice at Morce's Gap, Jamaica, on dead standing 

 saplings.
