ASPERGILLACEAE 633 



Obtained from human ear. Pathogenic to puppies, with production of 

 extensive lesions. 



Conidiophores up to 1,000;^ long ; vesicles 22-24/a in diameter, approxi- 

 mately spherical instead of cylindric, phialides hyaline, 10 x 4-4.5/x, more or 

 less divergent, covering upper two-thirds of the vesicle [while in A. fumigatus 

 the upper half only is covered, and the phialides measure 8 x 3-4/t] . Conidia 

 3-4/* in diameter. Perithecia are common, being particularly abundant on 

 bread. They are white, of woven hyphae, 40-60/x in diameter, surrounded by 

 a pseudoparenchyma. Asci 8-spored, 14-18/* in diameter, spherical, scattered 

 throughout the sclerotioid perithecium. Ascospores produced on bread in 7 

 days. Spores lenticular or biconvex, 6-8/i in long axis, colorless, having a 

 thick exospore with two ridges and a furrow and some markings on surface 

 of the valves. 



Colonies on agar gray blue. 



Judging from the figure, the antheridial hypha degenerates, unless Fig. 

 6 shows a much younger stage than interpreted by the author. 



Aspergillus fumigatoides Bainier & Sartory, C. R. Soc. Biol. 66: 22, 23, 

 1909; Bull. Soc. Myc. France 25: 111-118, PI. 5, 1909. 



A saprophyte found to be pathogenic to rabbits on inoculation. 



Foot tortuous, without partition, lightly and progressively curved from 

 bottom upward. Conidiophore short, 50-310/i high, 5-6/*, in diameter at the base. 

 Vesicle 30-35/1. broad, phialides 8-14/i long, wholly covering the vesicle, colorless. 

 Conidia dark olive, ovoid, small, 2-3/* in diameter. Perithecia appear on solid 

 media, 65-92/i in diameter, collected in masses. Asci spherical to ovoid, 20-26 

 X 12-18/1 with usually 8 ascospores per ascus, rarely 4, spherical, 3-3. 5/c in di- 

 ameter, rough. Organism not very heat resistant, dying at 48°-49° C. 



Color of cultures on carrot slightly green, not ashy gray fuliginous and 

 blackish as in A. fumigatus. 



Aspergillus bronchialis Blumentritt, Ber. Deutsch. Bot. Ges. 19: 442-446, 

 PI. 22, Figs. 1-6, 1901; 23: 419-427, PI. 19, Figs. 1-3, 6-8, 19, 23, 1905. 



Found by Chiari in the bronchial tubes of a diabetic patient. Studied 

 by Blumentritt. Not pathogenic to dogs and guinea pigs, pathogenic to hens 

 and pigeons (Luksch 1902). 



Aerial hyphae 5-8/t, submerged hyphae 2-4.2/t, conidiophores erect, simple, 

 seldom septate, hyaline, 280-300/i tall; vesicle 12-19/t, conidia gray, greenish 

 gray, and brownish, depending on medium, mostly gray green. 



On agar colony, at first white, then greenish, becoming dark green or 

 brown. On broth, white pellicle becomes green, tube finally filled with myce- 

 lium; obligate aerobe. On gelatin, colonies as on agar, gelatin liquefied after 

 a few weeks. 



Colony floccose in contrast to velvety in A. fumigatus. 



Aspergillus virido-griseus Costantin & Lucet, Ann. Sci. Nat. Bot. IX, 2: 

 119-171, 1905. 



Pathogenic to rabbits, not to fowls. Mori (1916) isolated it from the 

 pleuropulmonary exudate of goat.
