able from A. fumigatus. Perithecia were found with ascospores 
differing in detail from A. fischeri, A. malignus and the form we have 
described. 
A. fumigatus FreseniuS; Beitrage zur Mykologie, pp. 8i. pi. lo. 
figs. i-ii. Frankfurt. 1850-53. See Wehmer. Mem. Soc. Phys. 
Hist. Nat. Geneve 33: 70. 1901. Perithecial form described by 
Behrens, J. Centralbl. Bakt. 11: 335. 1892, and by Grijns, Cen- 
tralbl. Bakt. II. 11: 330. 1903. Vuillemin, Arch. Parasit. 8: 540. 
1904, decides that asci have never been found in A. fumigatus and 
that Grijns was dealing with A. pseudo-nidulans, while Behrens had 
some strain of A. glaucus. 
A. fumigatus var. tumescens Blumentritt, Ber. Deutsch. Bot. Ges. 
23: 419-427. pi. 19. figs. 5, 6, 18, 19, 20, 21. 1905. The culture 
described produced a dense, buckled, pseudo-parenchyma-like felt of 
mycelium with fruiting bodies not differing to any significant degree 
in measurements from A. fumigatus. Secondary heads from the 
outgrowth of sterigmata, branching stalks and septate stalks are 
figured. It is probably correctly characterized by the author a 
"culture cripple," since the differences are such as occur very com- 
monly as a result of some unfavorable condition. 
S. glauca Bainier, Bull. Soc. Bot. France 27: 29. 1880. The 
description of this Sterigmatocystis is not complete enough to indicate 
its relationships. 
A. glaucoides Spring, Bull. Acad. Sci. Belg. 19: 560-572. 1852. 
The name without description was given to a colony which grew in 
an egg under experiment. The same form was afterward found in 
another egg. It is recorded as closely related to, if not identical with, 
the mold found in air sacs of birds, hence probably A. fumigatus. 
A. gracilis Bainier, Bull. Soc. Myc. France 23: 92. pi. 9. figs. 11-13. 
1907. The description given by Bainier appears to relate A. gracilis 
to the A. fumigatus series. 
A. gracilis var. exiguus Bainier & Sartory, Bull. Soc. Myc. France 
28: 47. pi. 2. 1912. According to the description this variety differs 
in physiological characters slightly from A. gracilis Bainier. 
A. griseus Link, Sp. PI. 6: 69. 1824; Bonorden, Handb. Allg. 
Myk. p. 112. fig. 188. 1 85 1. This was referred to by Wehmer 
(Monogr. p. 90) as probably A. fumigatus. Neither the description 
of Link nor the description and figure of Bonorden can be identified 
with certainty.
