A. brunneus Bain. (Bainier, Georges. Sterigmatocystis et nematogonum. In Bui. 
Soc. Bot. France, t. 27 (s. 2, t. 2), p. 29. 1880). 
Colonies at first green, then black-brown; conidia 15 in diameter; probably 
A . glaucus series. 
A, brunneus Delacr. (Delacroix, Georges. Esp&ces nouvelles de Champignons in- 
ferieurs. In Bui. Soc. Mycol. France, t. 7, p. 109, pi. 7. 1891). 
Related to the preceding by color, 
5 . carbonaria Bain. (Bainier, Georges. Sterigmatocystis et mematogonum. In Bui. 
Soc. Bot. France, t. 27 (s. 2, t. 2), p. 27-28. 1880). 
A culture from Dr. Blakeslee reproduces the morphology recorded by Bainier. 
A redescription of the form is therefore givep. 
A. carbonarius (Bainier), Thom., n. comb. 
Colonies grown in Czapek’s solution agar show vegetative mycelium white or 
with some yellow in submerged areas, broadly spreading, more or less zonate; 
sclerotia produced upon the surface of the substratum in old cultures; fruiting 
areas carbon-black; stalks colorless below, yellow to yellow-brown toward the 
apex, 4 to 6 mm. or longer and up to 254 in diameter, with walls smooth, up to 
4 ju in thickness; heads globose varying in diameter up to 500/*, vesicles up to 
QOfi in diameter, fertile over entire surface, commonly with contents yellow- 
brown to black and in old heads forming with the primary sterigmata a hard brit¬ 
tle, carbonaceous mass; sterigmata in two series, primary sometimes 1-septate, 
from 20 to 40M long in young or small heads and up to 120 m long in large heads, 
5 to 13M in diameter at the apex, secondary 8 to 14M by 3 to 64; conidia at first 
smooth becoming rough When ripe, 5.5 to 10. 5 m in diameter. Colonies grow well 
upon all culture media used, with temperature optimum below 37 0 C. Growth 
at 37 0 C. slow and more or less dwarfed. 
A . cimmerius Berk, and Curtis (Berkeley, M. J. Notices of North American fungi. 
In Grevillea, v. 3, no. 27, p. 108, no. 656. 1875. Saccardo, P. A. Sylloge 
Fungorum . . . v. 4, p. 71. Patavii, 1886). 
The color reference “aterrimus” and the spore size, elliptical 7 m, suggest A. 
carbonarius , but the data are inadequate. 
A. cinnamomeus Schiem. (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. (i col.). 1912): 
Differentiated by color and smoothness of spores, but maintains these distinc¬ 
tions uniformly. Obtained as a mutant from A. niger by Schiemann.) 
A . cookeii (Cooke) Sacc. (Saccardo, P. A. Sylloge Fungorum ... v. 4, p. 71. Pa¬ 
tavii, 1886.)=A. mucoroideus Cooke (Cooke, M. C. Australian fungi. In Gre¬ 
villea, v. 12, no. 61, p. 9. 1883). 
Not recognizable from the description, but suggests a form of Syncephalas- 
trum which we have had in culture. 
A. echinosporus Sorok. (Sorok. Paras. 1 p. 40, pi. 7, fig. 82-87. Ref* in Saccardo, P. A. 
Sylloge Fungorum , . . v. n, p. 592. Patavii, 1895). 
The description suggests a Haplographium. 
A. ficuum (Reich.) Henn. (Hennings, P. C. Ustilago Ficuum Reich.=Sterigmato¬ 
cystis Ficuum (Reich.) P. Henn. In Hedwigia, Bd. 34, Heft 2, p. 86. 1895.)= 
Ustilago ficuum Reich. (Reichardt, H. W. Ein neuer Brandpilze. In Ver- 
handl. K. K. Zool. Bot. Gesell. Wien, Bd. 17, p. 335. 1867). 
Regarded as A. niger by Wehmer (Wehmer, Carl. Zur Kenntnis einiger Asper- 
gillus-Arten. In Centbl. Bakt. [etc.], Abt. 2, Bd. 18, No. 13/15, p. 394 - 395 * 
1907). 
Slight differences in morphology are reported by Hennings, but disregarded by 
Wehmer.
