G26 MEDICAL MYCOLOGY 



A saprophyte. The reports of pathogenicity of *S'. fusca by Sartory & 

 Joiirdre (1908) should be referred to Aspergillus Tamarii. 



Aspergillus Tamarii Kita, Centralbl. Bakt. II, 37: 433-452, 1913. 



A saprophyte. Found pathogenic for rabbits on inoculation by Sartory 

 & Jourdre (1908). 



Sartory & Jourdre describe their culture as follows: Conidiophores 800- 

 1,200/i high; vesicle 40-60/^, covered by phialides 18-26 x 10/a with 1-4 clavate 

 secondary phialides ; conidia spherical, echinulate, yellow, 5.5-6/i,. 



Growth on agar is slow, the surface becoming covered in 15 days. Colony 

 on potato is fertile in 2 days but sterile in parts, taAvny with snow-white mar- 

 gins 3-4 mm. broad. By the fiftieth day. surface is covered with a greenish 

 orange colony. (178, Code des Coideurs.) Growth on acid potato and car- 

 rot is the same. On coagulated egg albumen, growth weaker, chocolate brown. 

 On broth, growth also slow, filamentous flat thallus shows a mixture of nor- 

 mal and aspergilloid forms. On Raulin's normal medium at 22° C, colony is 

 fertile on the second day, smooth, yellow olive at first (157, Code des Cou- 

 leurs), orange next the liquid by the seventh day. In Raulin's neutral medium, 

 growth similar but less vigorous. Grows on Raulin's sugar media in order as 

 follows: maltose>sucrose>glucose>lactose. On lactose, filaments have a 

 chocolate brown color. Raulin's neutral gelatin becomes clear, colorless liquid 

 in 6 days. Broth gelatin is similar, with aspergilloid forms common in growth. 

 Egg albumen not liquefied. 



Thom and Church describe this organism as follows : 



"Colonies on Czapek's solution agar with cane sugar spreading broadly, 

 with vegetative hyphae mostly submerged, with fruiting areas at first color- 

 less, then passing through orange yellow shades to brown in old colonies 

 (variously Isabella color, light brownish olive, buff}' citrine, medal bronze or 

 raw umber. Ridgway, column 19, on Plates XXX, XVI, IV and column 17, 

 Plate III), not showing true green; reverse uncolored or occasionally pinkish ; 

 stalks arising from submerged hyphae, up to 1 to 2 mm. in length, becoming 

 several millimeters in length upon com or other concentrated media, 10-20/^ 

 in diameter, increasing in diameter towards the apex and passing rather 

 abruptlj^ into vesicles with walls rather thick, 1 to 2/a, becoming abruptly 

 thinner at the base of the vesicle, pitted more prominently in upper than in 

 lower half (often appearing as rough or echinulate with low magnifications) 

 and frequently showing irregular thickenings witliin ; vesicles 25-50;u, in diam- 

 eter, with fairly thin walls which frequently crush in mounts; heads varying 

 greatly in size in the same fruiting area, from more or less columnar to nearly 

 but not completely spherical and up to 350/i, in diameter, with radiating chains 

 and columns of conidia ; phialides, one series in small heads, two series in 

 large heads, primary commonly 7 to 10 b}' 3 to 4/x, becoming 20 to 35//. long 

 in gigantic heads upon corn, secondary 7 to 10 by 3/a; conidia more or less 

 pyriform toward globose, tuberculate especially at the distal end in the chain, 

 5, 6, occasionally up to 8/x in diameter, rough from prominent masses and
