A MANUAL OF THE ASPERGILLI 



.4. hennebergi Blochwitz, in Ann. Mycol. 33: 238-9. 1935. 



Colonies described as showing the colors and general aspect of ,4. tamarii or A. 

 wentii but with conidiophores browned as in the upper part of the conidiophores of 

 the A. niger group, and with "red" sclerotia; relationship doubtful. See also the 

 A. wentii group. 



Aspergillus niger van Tieghem, in Ann. Sci. Nat. Bot., s. 5, t. 8, p. 240. 1867. 



Van Tieghem 's strain is not fully verifiable among organisms now main- 

 tained in culture, although Biourge (personal communication) believed he 

 had it. We believe the name can be most appropriately used to cover

the exceedingly abundant isolates having the approximate measurements 

 of sterigmata and conidia noted in van Tieghem's description. The reader 

 can assume, therefore, that in the opinion of the authors any possible 

 description for the species itself would read essentially like that already 

 given for the series on pages 216-219. 



Species Characterized by Large Primary Sterigmata and Small Conidia

 the black Aspergillus found upon dates, Patouillard and Delacroix (Bui. 

 Soc. Myc. France 7: 118-120. 1891) compared their material to specimens
