218 MONOGRAPH OF CHAETOMIUM AND ASCOTRICHA 
but no further mention or description has been published. The 
plants here included are evidently not Chaetomia, for they consist 
of spherical or elongated, black pustules, firmly attached to the 
substratum by a broad base. There are no hairs with the excep- 
tion of a few bases of stout hyphae at the sides of the fruiting body. 
No spores could be obtained. The material in the Curtis her- 
barium which, according to a note, came from the herbarium of 
Schweinitz, and which undoubtedly represents authentic speci- 
mens, appears to be an Epicoccum. 
In the Nomenclator Fungorum of Streinz (100, p. 183) is found 
the following: “Chaetomium Montagnei Brond. in litt. ad M." 
This manuscript name, apparently used by Brondeau in a letter 
to Montagne, seems never to have been published. In the refer- 
ence quoted it is said to be identical with Ch. murorum Cda. 
In the Curtis herbarium is to be found under No. 5978 
the name Ch. subnudum B. & C. Examination of material here 
contained, which must have been collected previous to 1872, 
shows the fruiting bodies to be of the nature of pustules sunken 
in the tissues of the host, black and round or elongated. Тһе 
spores are dark bronze and one-septate. It is evident that the 
material is not that of a Chaetomium and so far as can be learned 
no description has ever appeared. 
THE Genus AscorRiCHA, HISTORICAL REVIEW 
A description of the genus Ascotricha was first published by 
М. J. Berkeley in the Annals of Natural History (5, р. 257). 
The characteristics were there cited as follows: “Peridium thin, 
at length bursting, clothed with dark, sub-pellucid, even, obscurely 
jointed hairs; sporidia simple, contained in linear asci. Super- 
ficial, at length free or only supported by the investing thallus, 
ack." In connection with his account of the genus, he gave à 
very full and complete description of a single species, 45. chartarum, 
and illustrated the same with six figures. Only one other form 
similar to that published by Berkeley is known. This was first 
described by Ellis in 1890, in the Proceedings of the Academy of 
Natural Sciences of Philadelphia, page 220, under the name 
Ch. pusillum. 
In 1871 Cooke included this genus in the Handbook of British
