Murrill: Polyporaceae of North America 331 



10. Hexagona caperata (Pat.) 



Favolus caperatus Pat. Bull. Soc. Myc. 18 : 171. 1902. 



Described from Guadeloupe collections. Easily recognized 

 by the abundant villosity which covers the cap. Plants recently 

 collected by Earle at Port Antonio, Jamaica, agree well with the 

 description. 



11. Hexagona brunneola (B. & C.) 



Favolus britiineolus B. & C. Jour. Linn. Soc. Bot. 10 : 321. 1868. 

 Collected on dead wood in Cuba by Wright. One small speci- 

 men is at Kew. The tubes are merulioid in their brevity, the dis- 

 sepiments being mere lines. I was at first inclined to consider the 

 species an undeveloped stage of H. purpurascens , but the two 

 species were originally described at the same time and declared 

 by their authors to be most distinct. 



12. Hexagona purpurascens (B. & C.) 



Favolus purpurascens B. & C. Jour. Linn. Soc. Bot. 10 : 321. 1868. 

 Collected by Wright on trunks in Cuba. Easily distinguished 

 from most other species by its purple color. 



13. Hexagona portoricensis sp. nov. 



Pileus centrally stipitate, circular, deeply umbilicate, x 4 0.3 

 cm.; surface subglabrous, umbrinous, the centre concolorous ; 

 margin entire, not very thin, much indexed when dry : context 

 white, fibrous, 1 mm. thick, opaque ; tubes somewhat decurrent, 

 white, 2 mm. long, 4-6 angled, mouths 1 x 3 mm., smaller and 

 more regular near the margin, edges thin, fimbriatulate ; spores 

 ellipsoidal, smooth, hyaline, 2-guttulate, 3-5 x 8-1 Otx\ stipe cen- 

 tral, compressed, slightly tapering downward, subconcolorous, 

 minutely tomentose, 2 cm. long, 4 mm. thick. 



The above description is based on no. i^j of Enrle's Porto 

 Rican collections. The plant was found upon decaying wood in 

 the mountains at an altitude of 2,000 feet. It has many characters 

 in common with H. hondurensis. 



14. Hexagona hondurensis sp. nov. 



Pileus centrally stipitate, circular, slightly umbilicate, 2-4 x 

 O.05 cm. ; surface faintly radiate-striate, subglabrous, fulvous, the 

 center fuliginous ; margin thin, regular, tessellate, inflexed when
