634 MEDICAL MYCOLOGY 



Colonies very floccose, areas partly white, partly g'ray, cream gray to dark 

 gray green or green; eonidiopliores thin-Avalled, septate, undulate, slightly 

 colored or tardily colored near the vesicle, 400-620/x, long, vesicle 25-36/a in 

 diameter, phialides 5/x in length; conidia 2.8/>i in diameter. 



Doubtfully distinct from A. fumigatus.

This is the commonest species isolated from cases clinically resembling 

 tuberculosis of the lungs in which Mycohacterium tuberculosis has not been 

 found. Apparently causing- severe epizootics in birds, less fatal in man, and 

 not reaching epidemic proportions. Pathogenic for laboratory animals. 



Conidiophores short, usually densely crowded, as long as 300/a (rarely 

 500/a) by 2-8ju in diameter, more or less green in color, especially above, arising 

 either from submerged or aerial hyphae, septate or unseptate, enlarging to- 

 ward the top with flask-shaped vesicles, 20-30/a in diameter, usually fertile 

 only on the upper half. Primary phialides only, 5-10 (mostly 6-8) x 2-3/li, 

 crowded, with axis approximately parallel to axis of the conidiophore. To- 

 gether with the chains of conidia, the growth is occasionally about 400/* high, 

 though usually shorter, and measures 50/jb across at the top. Conidia appear 

 dark green, spherical, 2-3.5 (mostly 2.5-3 )/x in diameter. Growth good at 

 37° C. 



Colonies on Czapek's solution agar velvety to felted floccose, green to 

 dark green to almost black in age, spreading. Reverse and medium colorless 

 to yellow, occasionally^ reddish in age. 



On the basis of ascospores reported by Sartory, C. R. Acad. Sci. 183: 

 1360-1362, 1926, Vuillemin erected Sartorya fumigata (Fresenius) Vuillemin. 

 C. R. Acad. Sci. 184: 136, 137, 1927. 



Perithecia in sclerotia, walls of several cell layers, spherical; asci ovoid 

 or spherical, thin-walled, disappearing at maturity. Ascospores 8, ellipsoid, 

 thick-walled, black at tips, lighter in centei ; perithecia 70-110/1, in diameter; 

 asci 15-22. 5/a; ascospores 4-6.25/j, long, perithecial filaments 3-5. 5/x in diameter, 

 walls 0.8-1.2/. thick. 



The perithecia were reported following treatment with x-rays. This work 

 has not been confirmed. Previous reports of perithecia in this species have 

 all been shown later to be erroneous.
