Type: authentie specimen of C. crocea in Burt Herb. 
Fructification effused, adnate, indetermi- 
nate, drying raw sienna, the margin of the 
same color, thinning out; hymenium even, 
compact, somewhat pulverulent; in structure 
60-120 м thick, with the hyphae giving their 
bright color to the fructification, not in- 
p D crusted, occasionally nodose-septate, 3—4 и in 
diameter, ascending more or less densely 
from the substratum to the hymenial surface; 
cystidia cylindric, not incrusted, simple, or 
few-septate, 4-4% ш in diameter, emerging 
20-60 д; spores concolorous with the hyphae, 
even, flattened on one side or slightly curved, 
6-7 x 215-3 и. 
Fructifications 4 em. long, 2-215 em. broad.

C. laeticolor. mont, Tennessee. September. Probably 
Section showing са 
hyphae, eystidium, rare. 
basidia, spores. This species suggests by its bright color 
and thin, adnate habit the conidial stroma of 
some species of Hypoxylon, and it may have been overlooked 
heretofore on account of this resemblance. It is well marked 
by its bright color, thin and compact habit of growth, small, 
slender spores, and cystidia. 
Specimens examined: 
Finland: Mustiala, P. A. Karsten, under the name Coniophora 
crocea. 
Tennessee: Elkmont, C. H. Kauffman, 70 (in Mo. Bot. Gard.
