332 MURKILL : POLYPORACEAE OF NORTH AMERICA 



dry, fringed with numerous short, fugacious cilia : context white, 

 fibrous, 0.25 mm. thick, translucent near the margin ; tubes adnate, 

 white, 0.3 mm. long, hexagonal, radially elongated, mouths 1 x 2 

 mm., much smaller near the margin, edges thin, subentire ; spores 

 ellipsoidal, smooth, hyaline, 3.5 x 9 ( « ; stipe central, equal, con- 

 colorous, pruinose to glabrous, 2-3 cm. long, 2 mm. thick. 



This species is described from plants collected in Honduras by 

 Percy Wilson {no. 64.0) March, 1903. They grew on dead logs 

 by the shore of a lagoon not far from the coast. All stages are 



represented. 



15. Hexagona indurata (Berk.) 



Favolus induratus Berk. Ann. Nat. Hist. II. 9: 198. 1852. 



Collected on wood in San Domingo. The type plants are at 

 Kew. If the tubes alone were considered, this species would 

 belong rather with Favolus. It differs from H. cucullata in having 

 larger tubes, and being purple in color. 



16. Hexagona cucullata (Mont.) 



Favolus cucullatus Mont. PI. Cell. Cuba, 378. pi. 14. f. 2. 1842- 

 Montagne's type from Cuba is well described and figured in 

 the work cited. Although the tubes are regularly hexagonal, it 

 seems best to place the species in Hexagona because of general 

 appearance, structure and habit. Berkeley considered Favolus 

 curtipes B. & C. (Kew Misc. I : 234. 1849) a synonym of Mon- 

 tagne's species, remarking that plants collected in San Domingo 

 exactly connect the Cuban species with that described from South 



Carolina. 



17. Hexagona Taxodii sp. no v. 



Pileus reniform, applanate, umbonate-sessile, 3-6 x 6-8 x 0.2 

 cm.; surface glabrous, radiate-striate, cream-colored to ochraceous, 

 marked with two or three broad undulations from center to mar- 

 gin, which is thin, entire, irregularly undulate or lobed and de- 

 flexed when dry: context tough, white, homogeneous, 0.5 mm. 

 thick; tubes dark fulvous, hexagonal, not radially elongated, 1.5 

 mm. long, I mm. wide, edges thin, finely denticulate ; spores 

 ellipsoidal, smooth, hyaline, 14x7/', copious; stipe a mere 

 scutate disk nearly a centimeter in breadth. 



The type collection of this species was made by Small & Wil- 

 son near Miami, Florida, May, 1904. The sporophores were
