THOM AND CHURCH — ASPERGILLUS 
Physiol. Ser., Bull. 12: 38. Pis. 3, 4. 1912. Speare found this form 
parasitic upon the mealy bug of sugar cane in Hawaii. The same form has 
also been found by us on mealy bugs from Demerara. Experiments, 
however, with known strains of the A. flavus group show that parasitism 
on the mealy bug is not confined to Speare's strain. 
A. perniciosus Inui. Jour. Coll. Sci. Imp, Univ. Tokyo 15: 473. 1901. 
Inui recorded a transient green phase in the colonies of this species which is 
otherwise compared to A. luchuensis and A. Wentii. In our cultures, 
A. luchuensis and A. Wentii have stalks smooth, not pitted as found by Inui 
in his form. The description suggests certain variant types among Takaha- 
shi's cultures such as N. 
A. pseudoflavus Saito. Centralbl. Bakt. II, 18: 34. figs. 15-18. 1907. 
Syn., S. pseudofiava Sacc. Sylloge Fungorum 22: 1260-1266. The mor- 
phology given indicates that A . pseudoflavus is one of the intermediate forms 
which bridge the gap between typical A. flavus and A. oryzae. 
A. siebenmanni Costantin & Lucet. Ann. Sci. Nat. Bot. IX, 2: 162. 
1905. This name is based upon Siebenmann's (Siebenmann, F. Die 
Fadenpilze A. flavus, niger, fumigatus, Eurotium repens und ihre Beziehung 
zur Otomycosis aspergillina. Zeitschr. f. Ohrenheilk. 12. 1883. Die 
Schimmelmycosen des menschlichen Ohres. Wiesbaden, 1889) description 
of an organism from the human ear identified by Siebenmann as A. flavus, 
but regarded by the describers from the description given by Siebermann 
as a separate species. The data given place the organism correctly in the 
A. flavus group but are not complete enough to separate it. 
A. tamari Kita. Centralbl. Bakt. II, 37: 433. 191 3. The strain 
described in the text was verified as A. tamari by Kita. Numerous strains 
of this group, some of which vary appreciably in cultural detail from the 
type, have been obtained from purely American as well as from Oriental 
sources. 
A. terricola Marchal (Marchal, Emile). Rev. Myc. 15: loi. 1893. 
See also Scales, F. M. Jour. Biol. Chem. 19: 459. 1914. The culture iso- 
lated by Scales was sent by us to Marchal and designated by him A. terricola 
var. Americana Marchal in this paper. 
A. terricola var. Americana Marchal n. var. cultural description Thom 
and Church. Colonies on Czapek's solution agar from shades near yellow 
ocher (Ridgway XV. 17) when young to Dresden brown or mummy brown of 
the same plate (near Saccardo's umbrinus) ; aerial growth consisting of 
crowded conidiophores, stalks 300 to 600 /x by 6 to 8 walls pitted; heads 
radiate; vesicles up to 20 ix in diameter; sterigmata in one series, 7 to 10 
by 2 to 4 /x; conidia tuberculate from the presence of color bars variously 
distributed between the outer and inner wall, ovate, from 3 by 5 m up to 
5 by 7 M or nearly globose, usually about 5.5 m» occasionally 5 to 8 m in 
diameter. Culture by F. M . Scales from Georgia soil . This variety ' ' differs 
from the type in measurements of vesicle 14 to 20 in diameter instead of 
40 to 50 At, in sterigmata 5.6 to 10.5 ixhy 2.2 jx instead of 12 to 15 m by 4 to 
7 m" (Marchal).
