Aspergillus niger Group 
15 
A. purpureofuscus Fries (Fries, E. M. Systemata Mycologicum. v. 3, p. 388. Gry- 
phiswaldae, 1829). 
The hyphae are described as purpureofuscus. This suggests certain of the 
A. glaucus series. 
A. purpureofuscus Schw. (Schweinitz, L. D. von. Synopsis fungorum in America 
boreali media degentium. Secundum observationes. In Trans. Amer. Phil. 
Soc., n. s. v. 4, p. 282, no. 2680. 1834. Saccardo, P. A. Sylloge Fungorum 
... v. 4, p. 68, Patavii, 1886). 
Not to be regarded as a member of this series from the description given. 
A. Schiemanni (Schiemann) Thom, n. comb.=A. fuscus Schiemann (Schiemann, 
Elisabeth. Mutationen bei Aspergillus niger Van Tieghem. In Ztschr. Induk. 
Abstam. u. Vererbungslehre, Bd. 8, Heft 1/2, p. 1-35, 16 fig., 2 pi. (1 col.). 
1912). 
A new combination was necessary because the specific name fuscus had been 
already used by Bonorden for a species of Aspergillus and fusca by Bainier for 
a species of Sterigmatocystis. This form is distinguished only by its fuscous 
conidia which are smooth or very delicately roughened. 
A. sirychni Lindau (Lindau, Gustave. Aspergillus (Sterigmatocystis) strychni nov. 
spec. In Hedwigia, Bd. 43, Heft 5, p. 306-307. 1904). 
This is regarded as A. niger by Wehmer (Wehmer, Carl. Zur Kenntnis einiger 
Aspergillus-Arten. In Centbl. Bakt. [etc.], Abt. 2, Bd. 18, No. 13/15, p. 394- 
395 - W)- 
The details of structure reported by Lindau for this form have been found in a 
culture (No. 2580) obtained in a study of red peppers (capsicum species) from 
Barcelona, Spain. The interior of these fruits had been destroyed and there 
remained a shell containing a mass of Aspergillus spores. The morphology 
obtained in cultures is identical with that of A. carbonarius, as described above, 
except that the conidia remain 4/* in diameter, as in the ordinary form of A. 
niger. 
A. ustilago Beck (Wawra, Heinrich. Itinera Principum S. Coburgi. T. 2, p. 148. 
Wien, 1888. Saccardo, P. A. Sylloge Fungorum . . . v. 10, p. 526. Patavii, 
1892). 
The description relates this form to the section of the A . niger group showing 
sterigmata 50JU or more in length. 
A . violaceo-fuscus Gasper. (Gasperini, G. Sopra un nuovo morbo che attacca i limoni 
e sopra alcuni ifomiceti. In Atti Soc. Toscana Sci. Nat. Pisa, Mem., v. 8, fasc. 2, 
p. 326. 1887). 
The conidia are reported as ovoid, 3 to 6 by 3 to 3.5^. This form' probably 
belongs elsewhere. 
A. welwitschiae (Bresadola) Hennings. 
This is regarded by Wehmer as A. niger (Wehmer, Carl. Zur Kenntnis 
einiger Aspergillus-Arten. In Centbl. Bakt. [etc.], Abt. 2, Bd. 18, No. 13/15, 
p- 394-393- 1907)- 
No data are reported which warrant the establishment of a separate species.
