266 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Fructifications 142-3 em. long, 1-2 em. broad. 
On coniferous bark and wood on the ground and on pal- 
metto. Ontario to Louisiana, and in Cuba and the Bahama 
Islands. July to April. 
С. olivascens is distinguished by its olivaceous color vary- 
ing by intermediate shades to almost bottle-green, by its small 
spores, and by having hair-like cystidia protrude from its 
granules, frequently in clusters, as in the genus Odontia, The 
granular hymenial surface appears to be more frequent in 
northern eollections than in those from the south, and the 
hyphae are more abundantly nodose-septate in northern speci- 
mens. Occasionally a collection will fail to show cystidia in 
a set of sections, especially if the fructification is rather 
young, but examination of other sets of sections from the old- 
est and most granular portions of the fructification will even- 
tually demonstrate cystidia. Grandinia virescens. Pk. is col- 
ored exactly like C. olivascens and has the same general habit, 
but the spores of G.virescens are darker and minutely aculeate 
when the fructification is fully mature.
