the name, Sordaria minuta. Winter accepts this name for the 
species, although it was not published until 1873.1 According 
to our modern rules, Winter’s name would hold for the species ; 
but it seems better at present to consider both forms distinct, 
thereby retaining both names. In all the material examined dur- 
ing the past two years only two specimens contained the 4-spored 
form. In all the other specimens where hundreds of perithegia 
were examined, for the express purpose of finding this form, not 
even a single ascus was observed to contain but four spores. 
In order to push the determination still further, the small quan- 
tity of the Wyoming material on hand was planted on a sterilized 
substratum of horse dung after it had remained in the laboratory 
in a dry state for about one year. In approximately four weeks 
mature perithecia were found in considerable numbers, and all 
contained 4-spored asci. The infrequency of this form, together 
with the constancy of this characteristic, appear to me to warrant 
its treatment as a distinct species. The fact that Winter found 
the two forms growing together argues but little, for one may 
often find any two or more of the species of this family growing 
with their perithecia completely intermingled. If both forms of 
asci were found in the same perithecium the question would be set- 
tled ; but there is no record of this ever having been done.
