Colonies on steep agar growing somewhat more rapidl}^ than on Czapek 

 but generally of similar texture, often more intensely colored with the 

 shades present on C'zapek more accentuated; conidial structures less 

 commonly monoverticillate than on C'zapek but otherwise conforming to

 same media, same age. 



Colonies on malt agar spreading broadly, thin but of looser te.xtiu'e than 

 on Czapek (fig. 81B), heavier sporing, usually in gray to glaucous graj' 

 shades, consistently lacking the colored myceliimi characterizing the same 

 strains on Czapek and steep agar; exudate not produced; reverse dull 

 yellow-brown, never in red-purple shades; penicilli commonly larger than 

 on Czapek but essentially similar in pattern.
