166 A MANUAL OF THE ASPERGILLI 



of Emericella and A. nidulans. He therefore transferred A. nidulans to 

 Emericella as the oldest established genus and apparently did not even 

 consider Inzengaea. 



Ciferri (1938) has recently completed a study of Emericella variecolor 

 embracing cultural investigations together with a review of the literature 

 of the genus. He did not recognize the close relationship of this fungus to 

 Aspergillus nidulans, and was apparently unmindful of the likeness of their 

 conidial structures and the essential similarity of their perithecia and asco- 



spores. 



In 1934 Curzi described as Aspergillus stellatus a fungus characterized by 

 hulle cells and red, stellate ascospores. However, he apparently did not 

 know of either Berkeley's or Borzi's earlier designation of a similar fungus. 

 It is unfortunate that his exceedingly descriptive binomial must be reduced 

 to synonymy. 



Fortunately for this discussion, cultures NRRL Nos. 212, 214, and 1954 

 present both the stellate spores and apparently stalked perithecia figured 

 by Berkeley, Patouillard, and Borzi. (Compare figures 42, F, and 44, 

 B with Berkeley's figure 76a, Patouillard 's figures 7 and 8, plate 4, and Bor- 

 zi's figure 10, plate 19.). This made possible a restudy of the whole 

 morphologic situation from fresh material. The perithecial body itself 

 was found not to be stalked but to rest upon a sterile mass of hulle cells 

 and mycelium giving the superficial appearance noted by earlier observers. 



The coremium of Borzi remains unaccounted for. Obviously in Borzi's 

 discussion the material was rotten olives and very old. No cultures were 

 made. The conidia-producing apparatus (figured) differs essentially in 

 type from the conidial apparatus of the Aspergillaceae with which Fischer 

 correctly placed Emericella because of its perithecia and ascospores. We 

 are convinced that the coremia belonged to some other fungus. 



It is not possible to separate the perithecium of this fungus from that of 

 the other species in the A. nidulans group nor are there characters to take 

 this type of perithecium out of a genus with the yellow perithecium of the 

 great A . glaucus series of species which are widely known. Consistent with 

 the policy of keeping the Aspergilli in one group, both Emericella and In- 

 zengaea are dropped for purposes of this discussion.

Colonies varying markedly upon different media; upon Czapek's solution 

 agar rather slow growing, attaining a diameter of 6 to 8 cm. in three weeks 

 at room temperature, plane or somewhat furrowed, mycelium largely sub- 

 merged and extremely tough, tearing with difficulty, producing numerous 

 dark green, hemispherical to loosely columnar heads in central colony areas,
