Jib.—FORMS DIFFERING FROM A. NIGER ONLY IN COLOR 
A. cinnamomeus Schiemann, 1912, in Ztschr. Induk. Abstain. 11. Vererbungslehre, 
Bd. 8, Heft p. 1-35, 16 fig., 2 pi. (1 col.). 
A.Schiemanni (Schiem.) Thom, n. comb. Syn. A. fuscus Schiem. (Schiemann, 
Elizabeth. Op. cit., 1912). 
III. —FORMS WITH BOTH PRIMARY AND SECONDARY STERIGMATA; PRIMARY 
ABOUT 50jU IN LENGTH 
A. phoenicis (Corda) Patouillard and Delacroix, 1891, in Bui. Soc. Mycol. France, 
t. 7, p. 118-120, pi. 9; syn. Ustilago phoenicis Corda, 1840, leones Fung., t. 4, p. 9, 
pi. 3, fig. 26. 
IV. —FORMS WITH BOTH PRIMARY AND SECONDARY STERIGMATA; PRIMARY 
UP TO I20JU IN LENGTH 
A. pulverulentus McAlpine, 1896, in Agr. Gaz. N. S. Wales, v. 7, pt. 5, p. 302; 
probable synonym A. strychni Lindau, 1904, in Hedwigia, Bd. 43, Heft 5, p. 306-307. 
V. —FORMS WITH BOTH PRIMARY AND SECONDARY STERIGMATA; PRIMARY 
UP TO 120 H IN LENGTH, SPORES DOUBLE SIZE 
A. carbonarius (Bain.), Thom (Bainier, 1880, in Bui. Soc. Bot. France, t. 27 (s. 2, 
t. 2), p. 27-28). 
The following list contains the names, original and often secondary 
citations, for the forms described as black or brown. Among these are 
some forms certainly not related to A . niger, but described in terms which 
might suggest such relationship unless critically examined. Wherever 
possible, the proper placing of the form is suggested. One original 
reference, that of Sorokin, has not been seen; all others have been crit¬ 
ically examined. The forms are arranged alphabetically to species 
without reference to the describees placing in Aspergillus or Sterigmato- 
cystis. 
S. antacustica Cramer (Cramer, Carl. Ueber eine neue Fadenpilzgattung: Sterig- 
matocystis. Cramer. In Vrtljschr. Naturf. Gesell. Zurich, Jahrg. 4, Heft 4, 
p. 325. 1859). 
In the external ear of man; considered A. niger by Wilhelm (Wilhelm, K. A. 
Beitrage zur Kenntniss der Pilzgattung Aspergillus. 70 p. Strassburg-Berlin, 
1877. Inaug. Diss.). 
A. airopurpureus A. Zimm. (Zimmermann, A. Ueber einige an tropischen Kultur- 
pflanzen beobachtete Pilze. II. In Centbl. Bakt. [etc.], Abt. 2, Bd. 8, No. 5, p. 
218. 1902). 
Not in the A. niger series; sterigmata and spores suggest the A. glaucus series. 
A. batatae Saito (Saito, Kendo. Mikrobiologische Studien fiber die Zubereitung des 
Batatenbranntweines auf der Insel Hachijo (Japan). In Centbl. Bakt. [etc.], 
Abt. 2, Bd. 18, No. 1/3, p. 34. 1907). 
Morphology given suggests A. niger in details, but in colony characters indi¬ 
cates a close relationship to A. wentii , Wehmer. This is confirmed by culture 
of a strain of A. wentii which showed this morphology.
