species, the forms are very similar, and while it is singular that 
he should call these species new unless he felt satisfied that they 
possessed sufficient distinguishing characteristics, especially since 
he had already named Ch. Fieberi, which has all the characteristics 
of Ch. globosum, still it does not seem unreasonable to the present 
writer to place these forms as synonyms under Ch. globosum 
Kze., on the ground that Corda was dealing with different stages 
of the same plant. 
In 1876 Dr. Peck redescribed Kunze’s species under the 
name Ch. lanosum. Mounts of original specimens which were 
received from Dr. Peck show the perithecia and spores typical 
in all their characteristics of the younger stages of Ch. globosum 
Kze. It may be well at this point to call attention to the fact 
that the Ch. lanosum Peck, in Roumeguére’s Fung. Gall. No. 
4437, is identical with the plant which Zopf described under the 
name Chaetomidium fimeti (Fckl.). 
The writer can hardly agree that it is desirable to apply the 
name Ch. Fieberi Cda., Ғ. lignicola chlorina to the plant which 
Dr. Saccardo found on moist wood, and which he described in 
1876, for the form seems in every way to be typical of Ch. glo- 
bosum Kze. If one examines young stages of Kunze’s species one 
frequently finds hairs which are straight for a considerable por- 
tion of their length, then taking a somewhat hooked turn, beyond 
which they become wavy. The same hooked characteristic is 
mentioned by Saccardo in his original description, but it may 
be seen from an examination of original material received from 
Dr. Saccardo, and from authentic specimens in Myc. Venet. X, 
No. 906, that such is true not of the mature perithecia, where the 
hairs are like those of Ch. globosum, but in the young immature 
plants. As for the color, it may be said that it is typical of 
Kunze’s species, and that the plant was growing on moist wood 
seems to be insufficient cause for setting it apart as a variety, 
especially since Ch. globosum will thrive on almost any substratum 
so long as it is moist. 
In 1877 Dr. Cooke described Ch. orientale, mounted material 
of which has been placed at the disposal of the writer through the 
kindness of the Royal Botanic Gardens at Kew. An examination 
of that material shows, in spite of the fact that the perithecia аге
