MONOGRAPH OF CHAETOMIUM AND ASCOTRICHA 211 
turia. Saccardo (79, 84) has recorded it under the name Venturia 
Alchemillae (Grev.) B. & Br., while other authors have given 
names as follows: Asteroma Alchemillae Grev. (37, 44); Coleroa 
Alchemillae (Grev.) Wint. (110, р. 199); Dothidea Alchemillae 
Rabh.; Dothidea ceramioides Duby (27); Stigmatea Alchemillae Fr. 
(39, р- 423). 
The plant to which Wallroth (109, р. 266) gave the name Ch. 
circinans is clearly not a Chaetomium. Saccardo (75, 79) has 
given to this form the name Venturia Kunzei, while other authors 
have applied the following names: Coleroa Chaetomium Rabh. 
(71, No. 1456); Dothidea Chaetomium Kze. (51); Stigmatea Chae- 
tomium (Kze.) Fr. (39; p. 422). 
The original description of Ch. coccodes, as given by Wallroth 
(109, p. 265), is very inadequate and it seems impossible to arrive 
at any satisfactory conclusion regarding it. Zopf (113, p. 205) has 
stated without further explanation that it probably represents a 
Chaetomium, but is rather to be considered as a slightly developed 
stage probably of Ch. crispatum Fckl. 
Regarding Ch. depressum of Wallroth (109, р. 266) it may be 
said that the original description is hardly that of a Chaetomium, 
but rather of an Excipula, since the perithecia are described as 
depressed-globose, sometimes oval, rough at the base, whence 
arise short, rigid, black hairs, exposing at the apex, where they are 
wide open, a disc of sporophores. | 
The original diagnosis of СЁ. epiphyllum Kze. appeared among 
the species of Wallroth (109, p. 265) mentioned above, as a note 
rather than as a description. The name was used by Kunze 
in connection with specimens which he enclosed in a letter to 
Wallroth, but so far as can be learned the species has never been 
described. Specimens of this species distributed in Klotzsch. 
Herb. Myc. No. 1347 are found to consist of minute, smooth, 
black pustules. 
Ch. oxysporium Wallr. (109, р. 242) is merely mentioned by Wall- 
roth in a description of a plant which he called Fusarium Chae- 
tomium. It is a name which he himself had privately used 
for this form at an earlier date, but which he had never published. 
The original description of Ch. Potentillae Wallr. (тод, р. 266), 
while of a brief and general nature, would hardly indicate a true
