Mycoderma cerevisia, and M. vini, Desmazieres. 

 Hormiscium vim, and H. cerwisice, Bonorden. 

 Cells oval, elliptic or cylindrical, about 6-7 /* long, 

 2-3 p, thick, united in richly 

 branched colonies. The cells 

 are often elongated, so as to 

 resemble a mycelium. Spore- 

 forming cells as much as 20 p.

the highest rank among the Saccharomycetes. The cells 

 often form, especially in watery fluids, long tubes, which 

 are divided by transverse partitions, and fall into single 

 pieces at those points. These bud, in their turn, in the 

 same manner.
