THE ASPERGILLUS GLAUCUS GROUP 



123 



Reverse persistent^ yellow under perithecial areas, more or less green 

 where conidial areas predominate. 



Perithecia globose to subglobose, mostly 115 to 140/x in diameter, occa- 

 sionally up to 160m, not covered by or embedded within a felt of sterile 

 hyphae (fig. 26 D); asci mostly 10 to 12/z, 8-spored; ascospores lenticular, 



Fig. 32. Comparative growth of members of the Aspergillus amstelodami series: 

 A, Typical A. amstelodami, NRRL No. 90; B, NRRL No. 113, a strain producing 

 abundant perithecia and few conidial heads; C, NRRL No. Ill, strain producing 

 abundant conidial heads and very few perithecia; D, A . montevidensis , NRRL No. 108. 



4.7 to 5.0m by 3.6 to 3.8/;, with prominent V-shaped equatorial furrow and 

 broad irregular ridges, and with walls roughened over their entire surfaces 

 (fig. 27 D). Conidial heads radiate-columnar, mostly 120 to 150m in 

 diameter, occasionally larger; conidiophores colorless to pale yellow-green, 

 275 to 350m in length, broadening to 10 to 12m in diameter below the 

 vesicle; vesicle subglobose, 18 to 25m in diameter; sterigmata about 5 to
