setae. The asci are cylindrical and contain subrotund or spherical 
spores arranged in a single row, and filiform paraphyses are 
produced among the asci. 
During the following year 1883, Roumeguére and Patouillard, 
in Rev. Myc. (5: 29), applied the name Therryana to a 
variety of Ch. atrum Link. A study of the original description 
and the accompanying figures together with an examination of 
authentic specimens in Fung. Gall. No. 2496, are sufficient to 
convince the writer that this variety has nothing in common 
with Ch. atrum but is identical with Chaetomidium fimeti (Fckl.) 
Zopf. During the same year Therry (102) made mention of Ch. 
exile, and whether he used this name by mistake or whether he 
purposely used it for a species which he intended to describe later, 
is uncertain. In either case it would seem advisable to exclude 
this, since, so far as can be learned, no reference has since been 
made to it, and no description has been published. 
In 1888 Roumeguére gave to a plant in Fung. Gall. No. 4438, 
the name Ch. globosum Kze., f. chartarum. The variety was 
not described, however, and so far as can be learned no mention 
or description has since appeared. From a study of mounted 
material from the authentic specimens, this plant is found to be 
identical with Chaetomidium fimeti (Fckl.) Zopf. : 
In 1892 Dr. Cavara (12) described under the name Ch. Monte- 
martinii a form which has characteristics similar to those of 
СЪ. Сабли: Sace. Ва the cam, however mounts of the 
type material received from Dr. Saccardo, and also of authentic 
exsiccati specimens in Fung. Longob. No. 228, show more clearly 
the exact nature of the plant. The perithecia, naked or scantily 
clothed with a few very slender, short hairs, are globose, flattened 
at the base, while from the top extends a cylindrical, curved 
neck, 70-80 in length. At the top of the neck an ostiole 1s 
located. In spite of several attempts to obtain asci none have 
been found. The honey-yellow spores which are produced in 
the perithecium and which in mass possess à decided orange 
tinge are poured from the ostiole in enormous numbers whenever 
pressure is brought to bear on the perithecium. From these 
observations it may be seen that this plant is not a Chaetomium. 
In 1894 Ellis and Everhart (34) described as new Ch. palli-
