MEDICAL MYCOLOGY 



after 8-10 months. Similar, but less luxuriant on lactose, maltose, and sucrose 

 agar; remaining pale yellow, small, punctiform on glycerol and peptone agar. 

 On malt agar, Ota reports cells larger, chains sometimes branched, cells up to 

 Sfj. in diameter. On potato and potato with glycerol, growth good, creamy, 

 white, smooth, shining, moist, 2-3 mm. thick, mammillate, the upper portion dry 

 and efflorescent, below in contact with the glycerol, colony moist, diffluent 

 with viscid or translucent streaks forming abundant mucous deposit. Finally, 

 the colony is ochre yellow to sepia, with new pale yellow colonies dotting the 

 surface of the old colony. After 6-8 months, the colony forms a thin dry 

 pellicle, almost scaly, gray or reddish above and almost black below. On car- 

 rot, a thin diffluent streak which never forms a thick colony. Ota reports

occasional chains, with branches several cells long. On gelatin, growth slow, 

 colonies grayish white, mucous. No growth on coagulated serum. On broth, 

 growth slow, with whitish flocculent or pulverulent deposit, no turbidity. On 

 sugar broths, limpid, ring formed but no pellicle, deposit a white clot which 

 disintegrates on shaking, producing turbidity which soon settles out. Ota 

 reports no ring in 30 days on malt extract, sediment brownish white. Gelatin 

 not liquefied ; sucrose inverted, glucose, maltose, and sucrose fermented, lactose 

 not fermented.
