Fig. 46. — Geotrichum versiforme. 1, 2, i, coenocytic cells, probably chlamydospores, on 

 Sabouraud agar ; 3, submersed mycelium showing branching, in Sabouraud agar ; 5, aerial 

 mycelium on same medium ; 6-8, cells stained to show volutin ; 9-13, cells showing glycogen as 

 dark heavily stained material, lipoids as small hyaline granules, and small dark chondriosomes ; 

 li-SS, cells showing volutin granules in the vacuoles ; 2S-S'i, living cells stained to show fat 

 content. (After Moore 1935.) 



Mycelium present, septate, forming arthrospores and terminal chlamydo- 

 spores. Growth at room temperature, but optimum at 37° C. 



On Sabouraud glucose and maltose agar, growth in 24 hours, colony cover-
