or 3.3m in diameter, with walls smooth or nearly so, in some strains lightly 

 colored, mostly simple but occasionally branched in the terminal area; 

 penicilli typically biverticillate and symmetrical (fig. 159D), usually con- 

 sisting of a single terminal verticil of metulae, often of different lengths 

 (the central metula usually longest), not infrequently showing individual

metulae rebranched below the level of the sterigmata, with walls of metulae 

 and sterigmata sometimes lightly colored in greenish tints; metulae mostly 

 5 to 8 in the verticil, about 10 to 13/i by 2.2 to 2.8m, occasionally longer; 

 sterigmata mostly in verticils of 5 to 7, closely parallel, about 10 to 12m by 

 1.8 to 2.2m but in individual strains often longer or shorter; conidia elliptical
