52 TROPICAL POLYPORES 



reddish-miniatous, scarcely a mm. long, mouths circular to 

 angular, regular, minute, 3-5 to a mm., edges thin, firm, entire, 

 concolorous with the interior; spores oblong, 3-4 X 1-2 /i. 



Extremely common throughout on all forms of dead wood. 

 A few specimens have been seen from Mexico and the Bahamas 

 which greatly resemble P. cinnabarinus.

 flabelliform, yellow throughout; surface anoderm, margin thin; 

 context very thin and friable; tubes small, thin-walled, fragile; 

 spores smooth, hyaline or yellowish. 



i. FLAVIPORELLUS SPLITGERBERI (Mont.) Murrill 



Pileus thin, dimidiate to spatulate-cuneate, densely imbricate, 

 gibbous behind, 2-4 X 3-8 X 0.1-0.2 cm.; surface anoderm, 

 fibrose-radiate, subzonate, smooth, flavous-luteous with reddish- 

 fulvous spots or zones, fulvous or umbrinous behind; margin 

 very thin, subfibrous, inflexed or folded when dry, broadly sterile, 

 golden-yellow; context radiate-fibrous, corky to woody, very 

 hard next to the tubes, I mm. thick, shining-flavous ; tubes 

 annual, melleous within, scarcely a mm. long, mouths circular 

 to angular, 4-6 to a mm., pale-luteous to melleous, edges very 

 thin, becoming dentate-lacerate with age; spores ovoid or ellip- 

 soid, subhyaline or pale-luteous, 4-5 X 3 M- 



Occasional on dead wood in Mexico, Panama, and Cuba; also 

 in South America. 



20. LAETIPORUS Murrill 



Hymenophore annual, epixylous, fleshy, anoderm, cespitose- 

 multiplex; context cheesy to fragile, light-colored; tubes thin- 

 walled, fragile, bright-yellow, mouths irregularly polygonal; 

 spores smooth, hyaline. 



i. LAETIPORUS SPECIOSUS (Batt.) Murrill 



Hymenophore cespitose-multiplex, 30-60 cm. broad; pileus 

 cheesy, not becoming rigid, reniform, very broad, more or less 

 stipitate, 5-15 X 7-20 X 0.5-1 cm.; surface finely tomentose to 

 glabrous, rugose, anoderm, subzonate at times, varying from 

 lemon-yellow to orange, fading out with age; margin thin, fer- 

 tile, concolorous, subzonate, finely tomentose, undulate, rarely
