account of the fact that it was found on wood, especially since a 
study of the authentic exsiccati specimens shows all structures to 
be typical of Ch. comatum (Tode) Fr. which, as we have seen, is 
synonymous with Ch. elatum Kze. 
Finally Kunze's species was redescribed by Ellis in 1893 
under the name Ch. glabrescens. It has been possible to examine 
type specimens of Ellis's species which are now in the possession 
of Dr. Farlow at Cambridge, and while the mounts contain 
for the most part rather fragmentary remains of perithecia, and 
while the hairs in most cases are broken below the point of origin 
of the first branches, still in other cases clusters of terminal hairs 
- show characteristics identical with those of Ch. elatum Кге. 
The spores also are typical of Kunze's species both in shape and 
size. 
All exsiccati mentioned above have been carefully examined and 
with two exceptions have been found to be typical of Ch. elatum. 
However, only plants of Chaetomidium fimeti (Fkl.) Zopf could 
be obtained from exsiccati specimens of Ch. atrum Link in Fung. 
Gall. IV, 325, and of Ch. atrum Link, var. Therryana Roum. et 
Pat. in Fung. Gall. XXV, 2496. Іп the specimens of Ch. panno- 
sum Wallr. in Myc. Ital. XV, 1475, perithecia of Ch. murorum 
Cda. appeared in considerable numbers. 
The following exsiccati specimens also consist wholly or in 
part of Ch. elatum Kze.: Ch. chartarum Ehr. in М. А. Е. No. 1541; 
Ch. Fieberi Cda. in Fung. Gall. No. 6409, Herb. Myc. No. 165, 
and Myc. Ital. No. 1288; Ch. Fieberi Cda., var. chartarum Roum. 
in Fung. Gall. No. 5827; Ch. Kunzeanum Zopf in Myc. March. 
No. 3246; Ch. lanosum P. in Fung. Gall. No. 4437; Ch. murorum 
Cda. in Fung. Europ., Series II, Edit. nova, ІП, 234; C^. oli- 
vaceum Cke. and Ellis in Myc. Univ. No. 1942 and in Fung. 
Columb. No. 512. 
No other species with which this should be confused have 
come to the attention of the writer with the exception of Ch. 
indicum Cda. and Ch. funicolum Cke., from both of which it 
differs in its large size, coarse appearance, and in the greater 
size of its spores,
