eter and 2.0m or more in length (fig. TGBs); couiditi elliptical, 2..") to 3.0m 

 by 2.0m, smooth-walled (fig. 76C), light vinaceous in mass. 



Colonies on steep agar growing more rapidly, attaining a diameter of 

 4.0 to 4.5 cm. in 10 days at room temperature with texture and general 

 colony appearance as on Czapek, generally heavier sporing, hence in darker 

 shades; penicilli essentiall}^ duplicating those on Czapek's agar. 



Fig. 77. A and B, Penicillium lilacinum Thorn, NRRL 895, on Czapek and malt 

 agars at ten days. C and D, Spicaria violacea Oilman and Abbott, NRRL 2015, on 

 the same substrata, same age. 



Colonies on malt agar as on Czapek's but generally more floccose, up to 

 5 or 6 mm. deep (fig. 77B), and with reverse commonly showing dark to 

 almost black shades in central colony areas, penicilli as above.
