8 A MANUAL OF THE ASPERGILLI 



use of the name Eurotium for all Aspergilli, or failing in that, for all ascosporic 

 strains, most workers have accepted the numerical predominance of the 

 non-ascosporic strains as ample reason for the general use of the name 

 Aspergillus. For practical purposes, Eurotium is not used here. 



Sterigmatocystis Cramer, in Vrtljschr. Naturf. Gesell. Zurich Jahrg. 4, 

 Heft 4, p. 325, Taf. II, figs. 1-15. 1859. * 



Cramer, in 1859, published his study of a black Aspergillus from the 

 human ear. Since the fruiting head differed from that of Fresenius' 

 A. fumigatus by showing a primary series of sterigmatic cells radiating 

 from the vesicle, each bearing a crown of several sterigmata, which in 

 turn each bore a chain of spores, he made this character the basis of his 

 new genus Sterigmatocystis. Cramer's name has been accepted by many 

 workers, but was rejected by Wehmer, Thorn, and others on the proof that 

 such use would separate strains obviously related in such a group as 

 Aspergillus flavus and its allies, and even among the black Aspergilli 

 studied by Cramer himself. The additional name serves no useful purpose 

 as an aid to identification; hence is not recognized here.

The proposal to apply a separate generic designation to all Aspergilli 

 producing sclerotia would take out the groups typified by A. candidus, 

 A. niger, A. wentii, A. tamarii, A. flavus, and A. ochraceus. No one has 

 followed Ludwig.

The black-spored Aspergilli were described as dematiaceous, hence 

 separated from all the other groups. No practical reason for accepting 

 this proposal has been offered.

Under this proposal ascosporic Aspergilli with the double series of 

 sterigmata would be separated with A. nididans Eidam as type. No 

 technical application of nomenclatorial rules justifies the complications 

 introduced. 



In addition to the above names proposed to cover blocks of species 

 with particular characters in common, a series of names have been used
