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, 

 ochraceous, 1-2 mm. long, mouths 4-6 angled, O.3-O.5 x 0.6-1 

 mm., edges rather firm, beset with small, sharp teeth ; spores 

 ellipsoidal, smooth, hyaline, 3x9^; stipe lateral to excentric, 

 slightly enlarged below, concolorous, minutely tomentose to sub- 

 glabrous, 1-7 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, Kelsey ; 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 H. 

 areolaris, 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. 



3. Hexagona daedalea (Link) 



Mcrulius daedaleus Link, Disser. 1 : 37. 1795. 



Daedalea braziliensis Fr. Syst. Myc. I : 332. 1821. 



Favolus braziliensis Fr. Elench. Fung. 44. 1828; Linnaea, 5:

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
