made up of a network of distinct colonies, but in the presence 
of saccharose the film is slimy and stringy in appearance. 
Dextrose and levulose are fermented. Gelatin is not lique- 
fied, and spores are not formed. 
Culture 7, Alternaria sp?—Colonies of this organism, ob- 
tained from the fruit of Ribes Grossularia, on gelatin or 
agar plates, appear much like the colonies of wild yeasts. 
At first they are made up of budding cells; later a 
few radiating strands of mycelium appear, with budding 
conidia at or near the cross walls. The culture soon becomes 
black from the formation of chlamydospores. The growth on

agar after seven days, results in the appearance of four 
distinct regions to each colony. The central part is black 
and shiny with a slightly wrinkled surface. About this 
area are three zones concentrically arranged and of a very 
dark green color, the terminal margin being made up of a 
filamentous growth. 
In nutrient sugar solutions, the film is at first white then 
black. Dextrose and saccharose are fermented. In yeast
