4-8 X 5-8. The culture does not become dark in any media 
and rarely forms chlamydospores. In yeast water containing 
organic acids only a few chlamydospores are found among 
the cells on the surface of the liquid. In nutrient sugar 
solutions and in yeast water containing organic acids the

vegetative growth results in the formation of a white, glisten- 
ing mass of fungous elements that cannot be separated easily. 
Only a few muriform many-celled spores are found, which 
indicates its being a species of Alternaria that does not 
readily form spores in culture. 
Culture 11, Alternaria sp?—This organism liquefies gelatin 
more rapidly and becomes black—due to the formation of 
chlamydospores—more quickly than any of the fungi pre- 
viously described. On gelatin or agar it first appears in 
irregular yeast-like colonies. The budding conidia develop 
rapidly; and if the colonies on the surface of the media
