 sparsely white, with oil drops, 4-5M thick; conidiophores ascending or 

 erect, ordinarily united in bundles or even twisted, septate, divided above 

 into one or more layers of forked branches, all terminated by chains of

The form of the cells depends on the chemical composition, the reaction, 

 and the state of aggregation of the substratum; for example, on peptone 

 gelatin the fungus produces predominantly long septate hyphas, while on 

 pieces of apple, yeast cells and short hyphal forms in almost similar 

 amounts arise. Practically, only round yeast cells containing 2-3 vacuoles 

 are produced in 10 per cent cane sugar solution, and these remain connected 

 in chains or clusters. In general, on solid sugar-free and neutral or alka- 

 line nutrient media, the tendency to form long cells predominates, while 

 in fluid, sugar-rich, weak-acid nutrient media, the specific yeast character 

 of round cells is predominant. On gelatin streaks short hyphas with 

 septa are formed, as well as elHptical to cylindrical cells. The latter are 

 4-5. 5 M broad by 5-10M long, the former (hyphae) are of different lengths, 

 with a width of s-8m.
