giving an entirely new name, in which latter case he would be 
disregarding a proper respect of the original author. He finally 
named Kunze’s species Ch. Kunzeanum in honor of the founder 
of the genus. It would hardly seem that this change was justi- 
fied, and in the present monograph, therefore, Zopf's Ch. Kunze- 
anum appears as a synonym under Ch. globosum Кге. 
In 1818 Ehrenberg added the name Ch. chartarum, the de- 
scription of which is indefinite and without figures. No mention 
is made of spores and the statements regarding the hairs and 
perithecia are of a most general nature. A description and 
figures of this species were published by Corda (23) in 1840, and 
there seems to be little doubt that the plant in question is iden- 
tical with Ch. globosum of Kze. Since Ehrenberg’s time certain 
writers have retained the name Ch. chartarum, but as it is reason- 
ably certain that Ehrenberg’s species is identical with that of 
Kunze, it seems most reasonable to list Ch. chartarum as а synonym 
under Ch. globosum Kze. 
In 1837 and 1840, in the Icones Fungorum, Corda described 
and figured four new species of Chaetomium: Ch. Fieberi, Ch. 
afine, Ch. amphitrichum, and Ch. Araliae. The simple, wavy, 
undivided hairs and the characteristic spores as described and 
figured would indicate that Ch. Fieberi is beyond a doubt identical 
with Ch. globosum Kze. The recognition of the three remaining 
species is not so easy, however, but it seems entirely possible that 
all these are forms of the same plant and should be listed under 
Ch. globosum Kze. Corda himself stated that Ch. affine is similar 
to Ch. globosum but was to be distinguished from it by the inverted 
egg-shaped spores. Zopf listed this in his monograph as а syn- 
onym to his Ch. Kunzeanum. Corda stated that Ch. Araliae and 
Ch. amphitrichum are distinguished from all other species of the 
genus described up to that time by the light color of their eom 
but in his diagnoses these spores are given characteristics not 
unlike those of other species. In two of the three diagnoses under 
consideration he failed to give the sizes of spores, a fact which 
makes а sure determination more difficult. If his figures and 
descriptions are studied with care it will be found that, with the 
exception of the egg-shaped spores of Ch. affine, and slight differ- 
ences in the shape of the hairs in the general figures of the three
