60 TROPICAL POLYPORES 



fuliginous to jet-black; margin pallid, thin, entire to undulate, 

 velvety; context membranous, fibrous, umbrinous to fuliginous, 

 1-2 mm. thick; tubes short, 1-2 mm. long, chalk- white within, 

 mouths circular to angular, becoming more or less irregular 

 and uneven, about 3 to a mm., edges avellaneous to cinereous, 

 firm, subentire, rather thin. 



Found once on an old pole on the summit of El Yunque, Cuba. 



14. CORIOLOPSIS CAPERATA (Berk.) Murrill 



Pileus thin, coriaceous, flexible, dimidiate to flabelliform, 

 narrowly attached, often laterally connate and subimbricate, 

 sometimes decurrent, 4-7 X 5-8 X 0.2-0.3 cm.; surface con- 

 spicuously tomentose, becoming aculeate, zonate, especially 

 with age, uneven, isabelline to umbrinous, with bay or blackish 

 zones; margin thin, undulate to lobed, sterile, almost white; 

 context thin, punky above, corky below, umbrinous-chestnut, 

 2-4 mm. thick; tubes short, avellaneous within, 1-2.5 mm. long, 

 mouths circular to subangular, regular, even, 3-4 to a mm., edges 

 rather thick, firm, entire, pale-isabelline or grayish-avellaneous 

 to pale-umbrinous ; spores 8-10 X 3-4 M- 



Common on dead wood throughout. 



15. CORIOLOPSIS SUBGLABRESCENS Murrill 



Pileus slightly flexible to rigid, sometimes reviving for several 

 seasons and presenting the appearance of a very thin Pyro- 

 polyporus, dimidiate to reniform, narrowly attached, decurrent, 

 usually applanate, 4-6 X 7-12 X 0.4-1 cm.; surface tomentose, 

 sulcate, umbrinous to bay or blackish, becoming glabrous and 

 bay-black; margin pallid, entire, acute; context thin, corky, 

 purplish-umbrinous, 2-3 mm. thick, becoming indurate and 

 blackish-encrusted above with age; tubes grayish-umbrinous, 

 often stratose, especially behind, 2-4 mm. long, mouths circular, 

 minute, regular, 5-6 to a mm., edges thick, entire, firm, avel- 

 laneous-isabelline to pale-umbrinous. 



Frequent on dead wood in Cuba, Porto Rico, and Jamaica. 



24. FUNALIA Pat. 



Hymenophore annual, epixylous, sessile, dimidiate, often semi- 

 resupinate; surface anoderm, hairy to aculeate; context light- 

 brown, more or less duplex, spongy above, coriaceous to woody 

 below; tubes usually large, thin- walled, more or less lacerate;
