THE ASPERGILLUS FUMIGATUS GROUP 151 



If the taxonomist could seize a half dozen widely spaced variants and 

 destroy those which bridge the gaps between, identification as separate 

 species would be easy. This, however, becomes impossible when large 

 numbers of isolates are cultivated and studied in comparative culture. In 

 attempting to divide this great series into tangible entities, earlier workers 

 have created a long list of species and, while we do not consider these to be 

 valid, they are presented in alphabetical order with the places of description. 

 It is believed that all of these should be regarded as synonyms of A . fumi- 

 gatus Fres.
