62 TROPICAL POLYPORES 



widely separated by thick dissepiments when young, 0.5-1 mm. 

 broad, pale-ferruginous, becoming darker with age. 

 Found several times on dead wood in Cuba. 



4. FUNALIA ACULEIFER (Berk. & Curt.) Murrill 



Pileus irregularly effused to imbricate and dimidiate, triangular 

 in section, 0.5-1 X 1-2 X 0.5-1.5 cm.; surface isabelline, very 

 uneven, broken up into projections, which vary in size and are 

 decorated with rigid cylindric or flattened latericeous aculeae; 

 margin thin, pallid, often indefinite or very irregular; context 

 white, spongy, 0.5-1 mm. thick, penetrated by the aculeae; 

 tubes very irregular in size and shape, 2-3 mm. long, white 

 within, mouths polygonal to radially elongate, averaging about 

 I mm. in width, edges thin, uneven to toothed or lacerate. 



Collected a few times on dead wood in Cuba and once at 

 Jalapa, Mexico; also in South America. 



25. TRICHAPTUM Murrill 



Hymenophore annual, epixylous, sessile, dimidiate; context 

 brown, firm and leathery below, very loosely fibrous and darker 

 above; tubes short, thin-walled, mouths polygonal, at times 

 becoming labyrinthiform ; spores smooth, hyaline. 



i. TRICHAPTUM TRICHOMALLUM (Berk. & Mont.) Murrill 



Pileus effused-reflexed, laterally connate, sometimes covering 

 the entire under surface of dead logs, the reflexed portion dimid- 

 iate, conchate, i-io cm. long, 5 to many cm. broad, 5-10 mm. 

 thick, thicker by overlapping ; surface fuliginous to almost black, 

 sometimes zonate, very conspicuously ornamented with long 

 intricately-branched hairs; margin thin, sterile, concolorous, 

 somewhat inflexed on drying; context light-brown, membranous 

 below, very loosely fibrous and darker above, the entire plant, 

 with the exception of the tubes and the very thin layer to which 

 they are attached, being composed of the loose branched fibers 

 mentioned above; tubes short, 1-3 mm. long, avellaneous within, 

 mouths angular, often irregular and sometimes daedaleoid, about 

 0.5 mm. broad, edges thin, entire, avellaneous, soon becoming 

 lacerate or irpiciform. 



Frequent throughout on dead logs. A very striking species. 



26. HAPALOPILUS P. Karst. 



Hymenophore annual, rarely perennial, epixylous, sessile, 

 dimidiate, simple or imbricate; surface anoderm, rarely pellicu-
