220 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
New Jersey: Newfield, J. B. Ellis, in Ellis, N. Am. Fungi, 
421, and also the cotype of Grandinia tabacina (in N. Y. 
Bot. Gard. Herb.). 
Ohio: A, P. Morgan, 525 (in N. Y. Bot. Gard. Herb., under 
the manuscript name Odontia olivacea). 
10. H. olivascens (Berk. & Curtis) Burt, n. comb. 
Zygodesmus olivascens Berk. & Curtis, Grevillea 3:145. 
1875. 
Type: type and cotype in Kew Herb. and in Curtis Herb. 
Fruetifieation effused, thin, not separable, tomentose, ci- 
trine, yellowish citrine or buffy citrine, the margin thinning 
out; КНО solution dissolves some of the color 
435 upon coming іп contact with the sections and 
becomes somewhat brownish in their vicinity;

sending out suberect branches which branch re- 
peatedly, become loosely interwoven, and are somewhat clus- 
tered; basal hyphae slightly colored, nodose-septate, thin- 
walled, 5-64 in diameter; basidia with 4 sterigmata; spores 
subglobose, concolorous with the basal hyphae, aculeate-echin- 
ulate, the body about би in diameter or 514-714 X 510-7. 
Fruetifieations sometimes in little patches 1-2 em. long, 
115-1 em. broad, sometimes growing more or less interrupt- 
edly over areas up to 15 em. long, 3 em. broad. 
On very rotten wood and on bark of fallen branches of 
both coniferous and frondose species. New Brunswick to 
South Carolina. September to November. Probably com- 
mon. 
H. olivascens is readily distinguished from other species 
of Hypochnus by its conspicuous citrine color of some kind 
(flavovirens of Saecardo's ‘Chromotaxia’) which has been 
retained well by the original collection for more than sixty 
years. From the description, Tomentella flavovirens v. 
Hohn. & Litsch. is but slightly, if at all, different from H. 
olivascens.
