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 brunneolus 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 inflexed 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 8-10; stipe cen- 
tral, compressed, slightly tapering downward, subconcolorous, 
minutely tomentose, 2 cm. long, 4 mm. thick. 
The above description is based on wo. r45 of Earle’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 
M common with A. hondurensis. 
14. Hexagona hondurensis sp. nov. 
Pileus centrally stipitate, circular, slightly umbilicate, 2-4 x 
°.05 cm. ; surface faintly radiate-striate, subglabrous, fulvous, the 
center fuliginous ; margin thin, regular, tessellate, inflexed when
