ous deciduous trees. In New York it appears to be most common 
on species of hickory: Canada, Dearness, Macoun ; New Hamp- 
shire. Lobenstine ; Connecticut, White, Earle; New York, Under- 
wood, Clinton, Brown, Murrill, Overacker, Earle; Pennsylvania,

2. Hexagona micropora sp. nov. 
Pileus flabelliform to reniform, convex, usually umbilicate or 
depressed behind, 2-4 x 2.5 x 0.2-0.4 cm.; surface smooth, gla- 
brous, straw-colored to cream-colored, margin acute, undulate or 
slightly lobed, rarely reflexed, irregularly denticulate, dark brown, 
as if scorched: context white, 1-2 mm. thick ; tubes decurrent, 
somigir ai 1-2 mm. long, mouths 4-6 angled, 0.3-0.5 x 0.6—-I 
edges rather firm, beset with pial sharp teeth ; spores 
ellipsoidal, smooth, hyaline, 3X 9/3 stipe lateral to excentric, 
slightly enlarged below, concolorous, minutely tomentose to sub- 
glabrous, I-7 mm. long, 3-5 mm. thick. 
The type plants of this species were collected by Miss V. S. 
White on a dead birch tree at Bar Harbor, Maine, August 4, 
1901. Other collections are at hand from Ohio, Ae/sey ; New 
York, Britton ; New Jersey, Ellis ; Wisconsin, Baker. Specimens 
were also found in the Fries herbarium at Upsala sent from New 
York by Peck. In habit and general appearance it resembles /7. 
alveolaris, but it is much rarer and seems confined to the northern 
states, while the glabrous surface and very much smaller tubes 
easily distinguish it from that species.

This species was originally described from Brazil, but it ex- 
tends as far north as Florida and is quite abundant in tropical 
America on fallen trunks and other decayed timber. Besides the 
synonyms cited above, there are doubtless several more recent 
ones assigned by those who have worked over South American 
material. On the other hand, some species have been treated as
