a form between the Saccharomycetes and the Torulae, in that it 
forms spore-like bodies under the ordinary conditions for spore 
formation, but these bodies are not true spores, as they neither 
form the spore wall, nor bud in germinating. It resembles 5. 
vosaceus, as heretofore described—excluding Swan’s descrip- 
tion —in appearance of colonies, and in not forming chains, but 
differs from it in forming spore-like bodies, and in size; S. rosaceus 
is 9-10 in diameter, a larger form than no. 1. No such form , 
is described in any of the standard works upon the Saccharo- 
mycetes, which would indicate that it is a new species. 
No. 2 is undoubtedly S. g/uéinis, in spite of the fact that it is 
not of the same size as the S. g/utinis as described in some of the 
later works. No. 2 answers the description in every other par- 
ticular. An error seems to have crept into the description of 
this species in regard to its size, the other characters being prac- 
tically the same in all the descriptions. Cohn? in 1875 gives 
4-5m@ as the size, while Winter? in 1881 gives it as 5-11 X 4p, 
Schréter,# in 1893, gives 5-6X 4-5, and Saccardo,5 in 1897, 
gives the same size as Winter, 5-11 4m. Jelliffe® in a list of 
Saccharomycetes occurring in the air gives S. glutinis among the 
number, but as he gives no description of his forms, it is impos- 
sible to tell which description he followed. The following 
description,? which was written by Schréter indicates probably 
the source of the error: S. glutinis (Fres.) F. Cohn (Zellen kuge- 
lig, 4-5 breit) und S. Fresenti Schroter (Zellen ellipsoidisch bis 
cylindrisch, bis 11m lang, 4-5 breit) schlagen sich haufig aus 
der Luft auf Leim nieder und bilden fleisch-bis rosenrote 
Schleimhaufchen. 
0. 3 from its peculiar appearance would seem to be easy of 
identification. In general appearance it is very like Mycoderma 
Humuli as described by Lasché,® but it is unlike in that MW. Hum-
