arising singly or grouped with others to form coremia. Conidial fructi- 

 fication consists of the three main branches bearing verticils of branchlets 

 supporting crowded whorls of conidiiferous cells 130-200 by 

 5o-6o)u at base in cultures without sugar, with sugar con- 

 tinuing for some weeks to produce a great number of 

 conidia that come to form masses perhaps i mm. in thick- 

 ness, conidiiferous cells 8-10 by 2-3^; conidia elliptical to 

 globose, 2 by 3. 3/1 or 3-3.4^1, green, homogenous, persisting 

 in chains when mounted. Colonies begin to liquefy gelatin 

 by sixth day.
