118 A MANUAL OF THE ASPERGILLI 



Aspergillus halophilus Sartory, Sartory, and Meyer (in Ann. Mycol. 28(3/4): 362- 

 363, PI. III. 1930) appears from the description based upon colonies grown upon 

 licorice sticks, to have been some member of this general group. No cultures have 

 been available for comparison, hence placement near A. proliferous of George Smith 

 can be only tentative. If placement were to be based upon their figure 12, it might 

 be a species of Scopulariopsis. 



ASPERGILLUS CHEVALIERI SERIES 



Ascospores lenticular, mostly 4.6 to 5.0> by 3.4 to 3.8m, occasionally up 

 to 5.2ju in long axis, with walls smooth or slightly rough, with crests prom- 

 inent, flexuous, often recurved, and with furrow conspicuous but consisting 

 more of a trough between extended equatorial crests than a depression in 

 the spore wall. 



Strains belonging to this series show appreciable difference in colony 

 character and to a limited degree in the surface markings of their asco- 

 spores. The ascospores of all, however, are characterized by their con- 

 tinuous, prominent equatorial crests which do not form an integral part 

 of the spore wall, but extend well beyond the margin of the spore body 

 proper. To use Mangin's exceedingly descriptive term, they are charac- 

 teristically "pulley-form." 



The following key will serve to differentiate groups of strains within the 

 series : 



A. Ascospore walls smooth. 



1. Crests prominent, thin, flexuous, often recurved 



A. chevalieri (Mangin) Thom and Church 



2. Crests evident, low, usually erect 



A. chevalieri var. rnultiascosporus Nakazawa et al 5 



B. Ascospore walls more or less roughened. 



1. Crests thin, flexuous, often recurved; conidia roughened. A. oriolus Biourge 5 



2. Crests thicker, usually erect: conidia smooth 



A. chevalieri var. intermedins, Thom and Raper

Colonies upon Czapek's solution agar (3 percent sucrose) restricted, 

 plane, closely felted, bluish-gray in center, with typical heads and peri- 

 thecia largely confined to marginal area (fig. 24 Ci); reverse maroon in 

 center to orange at margin. 



Colonies upon Czapek's solution agar with 20 percent of sucrose growing 

 best at 30° C. or above, spreading, plane to somewhat wrinkled in central
