A very common species of Chaetomium, having been found on 
substrata of very varied nature in nearly all countries (Chivers 
No. 26). Type locality: Leipzig; on dead stalks and leaves of 
various plants. 
Probably no species of Chaetomium is of so common occurrence 
as Ch. globosum, and certainly no other has been given so much 
attention both from a systematic and a morphological point of 
view. It was first described and figured by Kunze as a type 
form of his new genus, having appeared often in company with 
Sphaeria doliolum on dead stalks and leaves of various plants, in 
damp wet places in Leipzig, during the spring and autumn. It 
was described by that author as a globular fungus, a fourth of a 
line in size, black when in fresh condition, and entirely covered 
with hairs. His four very simple figures illustrate: a compara- 
tively young plant; a later stage when under the influence of 
moisture a punctiform opening appears at the crown of the 
fungus; a group of somewhat spherical transparent spores which 
were mixed with a gelatinous mass; and a cross-section through 
the body of the closed fungus. 
While, as may be seen, Kunze's description is of a general 
and indefinite nature, and his figures are quite inadequate for а 
sure identification of the form with which he worked, it seems 
reasonable to conclude that it is the same which Zopf described 
and figured in his monograph as Ch. Kunzeamum. For reasons 
not stated, but presumably on account of the fact that the term 
globosum might be applied to any one of several species, Zopf 
believed Kunze's form to be poorly named, and considered the 
alternative of retaining the old name though unsatisfactory ог of m
