Emic—Yerast FUNGI 253 
tures were made. Fisher regards this fungus as identical 
with M. racemosus, which is non- -Injurious to animals. 
RHIZOPUS 
R. niger Ciaglinski & Hewelke, Zeitschr. f. klin. Med. 
22 :626-632. 1893. 
This species, isolated by Ciaglinski (cited by Guéguen, 
08) from a case of **black-tongue"' and determined as Mucor 
niger, had an optimum growth temperature of 25-27°C., 
and was non-pathogenie for animals. The incomplete TN 
scription does not permit of an exact determination, and it 
is possible that Ciaglinski was dealing with R. nigricans. 
R. Cohnii Berl. & De Toni, in Sace. Syll. Fung. 7:213. 1888. 
According to Lichtheim (’82), this fungus, found with As- 
pergillus fumigatus on bread, has an injurious effect on rab- 
bits. Its oceurrence has not been reported in conditions of 
mycosis. 
MORTIERELLA 
Neumann mentions an interesting case of the parasitism 
of a species of Mortierella (1) in a cat which had died by 
asphyxia, presumably as a result of a fungous growth in the 
trachea. Costantin (’92) considered the fungus a new (?) 
species, probably belonging to Mortierella, since the spores 
of the known species of Mortierella do not germinate at blood 
temperature, 37°C. This determination cannot be accepted, 
since it depends exclusively on the presence of echinulate 
spores. 
ASCOMYCETES 
ASPERGILLUS 
A. aviarius Peck, N. Y. State Mus., Ann. Rept. 44:137. 
1891. 
This fungus was found by Peck (’91) in the body of a canary 
that had died after being sick a few days. No culture was 
made, and according to Wehmer, it is the same as A. fumi- 
gatus, for the determination was made from old fungous 
elements.
