Color yellowish green to green and later \arious shades of hrown; reverse of colony 

 orange, or yellow to deep orange, or even red; color in media yellow to orange to 

 red in media containing starch or sugar. 



< (dor, none. 



Fifteen per cenl gelatin in water, characteristic growth; liquefaction, none, or 



partial alter several weeks in acidified culture-; litmus reaction, strongly alkaline. 



Potato agar and bean agar, yellow-green to In-own, yellow below, coremia not closely 

 crowded as in sugar media. Potato plugs, characteristic growth, potato stained yel- 

 low to ilcc]) brownish yellow. Etaulin's fluid, characteristic growth. < John's solution, 

 germination only. 



Synthetic fluid (Dox's), carbon supplied as: Cane sugar, 3-30 per cent , characteristic 

 growth and colors, hut not normal at 00 percent, with acid reaction. Lactose 3 per 

 cent, characteristic structure but weak development. Lactic acid 0.9 per cent, 

 growth, hut not normal colonies. Levulose :5 per cent, slow development, small colo- 

 nies. Galactose 3 percent, characteristic. Glycerin :'. percent, slighl growth, grew 

 freely when cane sugar was added. Potato starch, characteristic. Butterfat, typical 

 growth, reverse and fluid orange; yellowish. 



I i'.. n. i'i nirillium granulaium Balnier: a, b, c, branching of conidlal fructification showing granu- 

 lated echinulated cell walls (x 900); d, e, f, g, conidiiferous cells and conidlal chains ( < 1,400); h, j, k, 

 sketches of fructifications (X 140); m, sketches drawn from photomicrograph of coremia showing fertile 

 and sterile areas (X about 25). 



Milk, rapid and characteristic growth; curdling, none; digestion, slow but complete 

 (fairly); color in milk, yellow to orange to deep red. 

 At 37 C, no growth, conidia grew when removed to Lower temperal ure; at 20° < '., 



excellent gTOWth.
