No growth on agar. On glycerol agar, colony white, dry, with slight 

 efflorescence, resembling a bacterial colony. On glucose and maltose agars, 

 colonies granular, opaque, milky white, thick. On potato, colony white, dry, 

 viscous, cerebriform, becoming clear gray, efflorescence white ; medium pig- 

 mented yellow, becoming brownish. On broth, pellicle thin, white ; liquid
