330 MurRILL: POLYPORACEAE OF NORTH AMERICA 
quite thick for the genus, nearly regular in outline, usually in- 
flexed when dry, partly hygrophanous at times, beset with short, 
fimbriate, fugacious hairs: context thin, white, partially translu- 
cent, quite fragile when dry; tubes decurrent, white, 2-3 mm. 
long, 4-6 angled, mouths 1x 4 mm., becoming radially confluent 
and gill-like, edges thin, lacerate, the divisions fimbriate ; spores 
ellipsoidal, smooth, hyaline, 4-5x 10 #2; stipe lateral, subequal, 
concolorous, hispid, short, 5 mm. long, 2.5 mm. thick, rarely um- 
bilicate above. 
About twenty specimens of this plant were collected by Earle 
(xo. 585) during a recent visit to Jamaica. They were found on 
fence-posts made of ‘‘ star-apple”’ (Chrysophyllum). 
8. Hexagona floridana sp. nov. 
Pileus flabelliform, applanate, depressed behind, 2x 2.5—3 x 0.2 
cm.; surface finely hispid, pure white becoming straw-colored on 
drying, faintly radiate-striate ; margin slightly undulate, tessellate 
at times, fringed with numerous slender cilia : context very thin, 
white, membranous, wholly translucent ; tubes decurrent, white, 
becoming ochraceous, 1.5-2 mm. long, normally hexagonal, 
mouths 0.5—I x 2-3 mm., not radially confluent, edges thin, fim- 
briate; spores ellipsoidal, smooth, hyaline, 9x4; stipe lateral, 
subequal, scutate at the base, concolorous, hispid, 2-5 mm. long, 
I—2 mm. thick, always umbilicate above. 
This species was collected by Small & Wilson near Miami, 
Florida, May, 1904. About thirty sporophores in various stages 
of development were taken from an old decaying log in rich 
shady woods. 
9. Hexagona tessellatula sp. nov. 
Pileus flabelliform, convex, depressed behind, 1-3 x 2-4 0-2 
cm.; surface delicately and closely tessellate, finely hispid, becom- 
ing glabrous, white, yellowish when dry ; margin thin, denticulate, 
slightly incurved when dry, frequently brown and hygrophanous : 
context white, membranous, translucent; tubes decurrent, white, 
2 mm. long, 4-6 angled, mouths 1x 3 mm., at length radially 
confluent, edges thin, lacerate ; spores ellipsoidal, smooth, hyaline, 
2-guttulate, 3x 104; stipe lateral, short, slightly enlarged below, 
concolorous, hispid, 3-5 mm. long, 2-3 mm. thick, usually um- 
bilicate above. 
This species was recently collected on dead wood in Cuba by 
Underwood and Earle (xo, 7272). About twenty fruit-bodies were 
preserved.
