EREMASCACEAE IMPERFECTAE 



211 



Colony dull white, circular or oval, with sharp contours, becoming radially 

 and spirally folded, turning yellowish and finally brownish. Growth best on 

 sugar, potato, and gelatin media, poor on serum and ordinary agar. No fer- 

 mentation. Yeast cells gram-positive (Fig. 42). 



Near P. Balzeri, considered by Ota, Ann. Parasitol Hum. Comp. (1926) as 

 close to P. cutcmeus, later considered distinct.

Produced hypodermal and dermal gummatous infiltrations, later becom- 

 ing ulcerated. 



On glycerol agar are formed yeast cells, spherical or ovoid, 4-8/x, elongate 

 forms 3-4 x 20/t, sometimes agglomerating. Cultures smooth, shining, viscous, 

 growth good (Fig. 43). 



On peptone glucose agar, these yeast cells give rise to pseudofilamentous 

 cells 4-5 X 8-10/x and filamentous forms of cylindric cells with terminal chlamy- 

 dospores 8-12^ in diameter. In a purely filamentous stage, cells are 2-4 x 20/i,
