230 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
strands 6-15, in diameter, and (2) with hyphae in the sub- 
hymenial region densely interwoven; no cystidia; basidia 
with spores on 4 slender sterigmata; spores olive-ocher, 
angular-subglobose, aculeate, the spore body 5-6 X 415-06; 
KHO solution changes the color of both the olive-ocher and 
the brownish drab hyphae to sage-green, later olive-gray. 
Fruetifieation 2 em. long, 114 em. broad, with the fertile, 
olive-ocher portion 5-10 mm. in diameter. 
On dead wood in woods. New York. August. 
The single collection of this species which has been found 
is conspicuous by its bright olive-ocher hymenial portion 
surrounded by a brownish drab margin. Both of these colors 
are destroyed when potassium hydrate solution is brought in 
contact with sections of the fructification in making micro- 
scopic preparations, and the hyphae become at once sage- 
green, later olive-gray.
