Type: in Herb. Fries; the specimen in Kew Herb. from 
Fries and named by him Thelephora olivacea is Coniophora 
Betulae. 
Fructification effused, adnate, somewhat felt-like, and sep- 
arable from the substratum with a scalpel, 
drying buffy citrine апа Saceardo's olive 
to brownish olive, the margin thinning out 
and sometimes whitish; hymenium even, 
tomentose, setulose; in structure 200-700 д 
thick, composed of more or less colored 
Or 
Qy с hyphae 3-6 шіп diameter, not nodose- 
septate, not usually incrusted, which are 
(2 loosely interwoven next to Ше substratum 
and form a very dense hymenial layer; 
eystidia septate, granule-incrusted, taper- 
ing upward, concolorous with the hyphae 
at the base, paler above, 8-12 y in diameter, 
protruding 50-100 д; spores colored, even, 
7-12 414-514 и, often flattened on one 
side. 
Fructification 4-10 ет. long, 2-5 em. 
broad. 
On coniferous wood and bark, rarely on 
“er frondose species. Canada to Louisiana 
T n and westward to Idaho. 
Spores, protruded por- C. olivacea is paler externally and in-

eystidia, and hyphae with usually thinner 
walls and often collapsed. I have been able to detect no mor- 
phological characters which sharply separate these species. 
I was not able to study in Herb. Fries the original collection 
from Femsjó of Coniophora olivacea, for the specimen was 
loaned to Bresadola when I was at Upsala. I have presented 
C. olivacea as understood by Bresadola in the specimen com- 
munieated to me by him and cited below. The specimen of
