A. fuliginosus Peck (Peck, C. H. Descriptions of new species of fungi. In Bui. 
Buffalo Soc. Nat. Sci., v. 1, p. 69. 1873. Peck, C. H. Reportof the botanist. 
In 26th Ann. Rpt. N. Y. State Mus. Nat. Hist. [1872], p. 79. 1874). 
No valid data are offered for separating this strain from A. niger. 
A.fuscus Bonorden (Bonorden, H. F. Beitrage zur Mykologie. In Bot. Ztg., Jahrg. 
19, no. 29, p. 202. 1861). 
This is probably a very common form of Haplographium. 
S.fusca Bain. (Bainier, Georges. Sterigmatocystis et nematogonum. In Bui. Soc. 
Bot. France, t. 27 (s. 2, t. 2), p. 29. 1880). 
The morphology recorded differs from A. niger in the size of the conidia, “ less 
than 9.4M. ” The form has not yet been found by us. 
A.fuscus Schiem. (Schiemann, Elisabeth. Mutationen bei Aspergillus niger van 
Tieghem. In Ztschr. Induk. Abstam. u. Vererbungslehre, Bd. 8, Heft 1/2, 
p. 1-35, r6 fig., 2 pi. (r col.). 1912). 
This mutant from A. niger is distinguished by the color and smoothness of its 
spores from the parent strain. The name of this and the preceding form are 
invalidated by the occurrence of the name A.fuscus Bonorden. 
A. japonicus Saito (Saito, Kendo. Nachtrag zu der Abhandlung “ Untersuchungen 
iiber die atmosphaerischen Pilzkeime, I.” In Bot. Mag. [Tokyo], v. 20, no. 233, 
p. 61, 5 fig. 1906). 
This species as described differs from A. niger in having but one set of sterig- 
mata and showing granules at times upon the walls of the conidiophore. It is 
evidently very closely related to the regular forms of A. niger. 
A. luchuensis (Inui, T. Untersuchungen iiber die niederen Organismen welche sich 
bei der Zubereitung des alkoholischen Getrankes. "Awamori” betheiligen. 
In Jour. Col. Sci. Imp. Univ. Tokyo, v. 15, pt. 3, p. 469. pi- 22 > fi g- 1-8 • I 9 01 )- 
This form differs from A. niger by showing green colors when young and by 
morphological details. It does not, therefore, belong in this series. 
A. mucoroideus Cooke (Cooke, M. C. Australian fungi. In Grevillea, v. 12, no. 61, 
p. 9. 1883). 
A. cookei Sacc. 
A. mucoroideus Corda (Corda, A. C. I. leones Fungorum . . . t. 2, p. 18, pi. n, fig. 
76. Pragae, 1838). 
This is a different organism and not in this group. The description suggests 
A . castaneus Patterson. 
A nanus Montague (Montague, J. F. C. Sylloge Generum Specierumque Cryptogama- 
rum . . . p.300,no. 1112. Parisiis, 1856. Saccardo, P. A.- Sylloge Fungorum 
... v. 4, p. 71. Patavii, 1886). 
The description clearly distinguishes this organism as a member of the group 
and as having a single series of sterigmata about 15/z in length and spores 3At m 
diameter. 
A. niger Van Tieg. (Van Tieghem, P. E. E. Recherches pour servir a l’histoire 
physiologique des Muc6din6es. Fermentation Gallique. In Ann. Sci. Nat. 
Bot., s. 5, t. 8, no. 4, p. 240. 1867. )=S. nigra Van Tieg. (Van Tieghem, P. E. E. 
Sur le developpement de quelques Ascomycetes. In Bui. Soc. Bot. France, t. 
24, p. 102-103. 1877). 
Described by Van Tieghem as the active agent in fermenting tannin solutions. 
A. nigrescens Robin (Robin, C. P. Histoire Naturelle des V^getaux Parasites . . . 
p. 518; atlas, pi. 5, fig- 2. Paris, 1853). 
The organism of Robin has been called A. niger by Wilhelm (Wilhelm, K. A. 
Beitrage zur Kenntnis der Pilzgattung aspergillus.' 70 p. Strassburg-Berlm, 
1877 Inaug. Diss.), A. fumigatus by Siebenmann (Siebenmann, Friedrich.
