254 ANNALS OF THE Missourt BOTANICAL GARDEN 
A. bronchialis Blumentritt, Ber. d. deut. bot. Ges. 19:442- 
446. 1901. 
A species of Aspergillus was discovered by H. Chiari, in 
the trachea of a diabetic patient. Blumentritt (201, 705) 
gives a full account of this fungus which agrees with the de- 
scription of Wehmer for A. fumigatus. Blumentritt admits 
that A. bronchialis is very closely related to A. fumigatus 
and ean be distinguished from it only by a few minor physi- 
ological characters. 
A. candidus Link, Observationes 1:65. 1809. 
A. candidus was obtained from a patient affected with 
otitis, in which case it appeared as a saprophyte, its optimum 
growth temperature being 25°C. 
A. flavus Link, Observationes 1:14. 1809. 
In pure cultures on various media usually of a yellow- 
green to a light brownish green color; mycelium sterile, 
always grayish white and even hyaline; conidiophores not 
very conspicuous, usually 500-700и in length, 7-10 thick, the 
terminal swelling colorless, spherical to clavate, 30-40» in 
diameter, with conidia about 854; sterigmata undivided, 
20 x ба, crowded, arranged radially; conidia varying in 
size, spherical, smooth, rarely papillate, 5-7» in diameter. 
This species, frequently found in the ear as a saprophyte, 
and A. flavescens Wreden, are considered by Siebenmann 
(289) as identical. According to Ribbet, the spores of this 
fungus are toxic for rabbits. Wreden (cited by Plaut, '03) 
considered A. flavescens as a variety of A. glaucus, but new 
descriptions of the former species are lacking, and in recent 
literature we find A. flavescens appearing as a synonym of 
A. flavus. 
A. fumigatus Fres. Beitr. z. Myk. 81. 1850. 
A. nigrescens Robin, Veg. Par. 518-528. 1853. 
Forms a greenish layer in fruiting cultures; mycelium 
much branched, 2-3, in diameter; conidiophores scarcely dif- 
ferent from the hyphae, formed in dense tufts, 100—300, 
long, 5-би thick; terminal swelling small, green, clavate, ta-
