SCHIZOBLASTOSPORION 



Schizdblastosporion Ciferri, Arch. Protistenk. 71: 446-448, Fig. 6, 1930. 



The type species is ScMzohlastosporion Starkeyi-Henricii Cif. (Torula A 

 Starkey & Henrici 1930.) 



Colony creamy, white, or slightly yellowish. Turbidity and sediment on 

 liquid media, sometimes a trace of a ring but no pellicle present. Blastospores 

 spherical or slightly ellipsoid ; mycelial cells elongate, ellipsoid ; pseudomyce- 

 lium somewhat branched. No fermentation of sugars; gelatin liquefied. 



This genus is not well known, but three organisms of skin and nails seem 

 to belong here. The genus seems intermediate between Geotrichum and 

 Parendomyces. 



Key to Species

Schizoblastosporion gracile (Zach) Dodge, n. comb. 



Blast odendrion gracile Zach in Wolfram & Zach, Arch. Derm. Syphilis 

 169: 95-104, 5 figs., 1933. 



Isolated from a case of onychomycosis in Austria. 



Cells spherical to ovoid, 2.7-3.2 x 6.5, mostly 5.4 x 6.5/a. Mycelial cells 

 elongate, ends rounded, 2.5-3.2 x 19.5/i, thin-walled with one small oil globule 

 when young, later with a gelified wall, a large central vacuole, and 1-2 oil 

 globules. Sprouting only at the poles. No ascospores. 



Colonies on maltose agar, dull, whitish, smooth with a smooth margin, 

 later yellowish with a central elevation but without folds, margins sometimes 

 showing pseudomycelial outgrowths. On gelatin, colony thin, white dull, 

 margin wavy, slightly sinking into the medium. On acid potato, colony 

 thicker, smoother more shining, grayish yellow. On carrot, colonies similar 

 but white. In maltose broth and in yeast water, sediment slightly flocculent, 

 no turbidity, no pellicle. In yeast water sometimes a slight turbidity. Growth 

 good at 37° C. No fermentation, gelatin liquefied in 3 weeks. 



Schizoblastosporion globosum (Zach) Dodge, n. comb. 



Blast odendrion glohosum Zach in Wolfram & Zach, Arch, Derm. Syphilis 

 169: 95-104, 5 figs., 1933. 



Isolated from a case of onychomycosis in Austria. 



Cells spherical, mostly 5-5.5/a, giant cells up to 10.8-12. 8ju,. Pseudomycelial 

 cells elongate up to 30/t long, slender, producing short ellipsoid blastospores, 

 sometimes almost lacrimiform, in depauperate whorls. Sprouting not confined 

 to the poles. No ascospores. 



Colonies on maltose agar dull, smooth, white, later slightly yellowish, 

 margin wavy to dentate, sometimes showing pseudomycelial outgrowths. On 

 gelatin, colony similar but weaker, somewhat striate and verrucose, margin
