EREMASCACEAE IMPERPECTAE 



213 



in old cultures occasionally up to SAfi in diameter, cells mostly 2-2.5 x 14-28/t. 

 Chlamydospores 8/t in diameter, yellowish. No asci found (Fig. 44). 



On peptone glucose agar, growth whitish yellow, becoming more or less 

 dark, elevated, cerebriform. Moist at first, then waxy and dull. Gelatin not 

 liquefied; sugars not fermented [Ota].

On beet, pseudomycelial cells, elongate, 1-2 x 6-7/x, blastospores 2-3 x 1/x.. 

 On Sabouraud agar, yeast cells predominate, 1-2/a sometimes up to 4 or 5/n in 

 diameter. Division either by sprouting or by equal fission. Oil droplets abun- 

 dant in old cells. On vegetable decoctions with sugar, mycelial forms pre- 

 dominate. In the deposit are small white masses or spheres of mycelium which 

 are sterile or show rare chlamydospores. On coagulated serum hj^phae l-3yu. 

 in diameter, blastospores 1-2/x. Optimum temperature for growth 15-18° C, 

 but growth still good at 37° and slight at 45° C. Antiseptics rich in oxygen 

 (e.g., KMn04, H0O2) do not check growth but produce gigantism (cells of 

 double size). 



On carrot, glycerol, beet, or gelatin at 16-18°, colonies begin as small, 

 rounded excrescences with small crater, opaline. Later colonies confluent, 

 folded, vermiculate, and finally cerebriform. On carrot it is dry or waxy.
