208 MEDICAL MYCOLOGY 



Gelatin not liquefied. 



Sugars not fermented. 



Pseudomycelium little branched. Parendomyces. 



Pseudomycelium branched, colony dull, pellicle present. Pseudomonilia. 

 Sugars fermented. 



Morphology unknown, no pellicle on liquid media. Castellania. 



Blastospores pointed at one end, in dendroid clusters. Blastodendrion. 

 Blastospores spherical or ovoid, verticils compound 



elongate. Mycotoruloides. 



Blastospores elongate-ellipsoid, verticils rudimentary, reduced to 2 spores each, 

 colony folded. Mycocandida. 



PROTEOMYCES 



Proteomyces Moses & Vianna, Mem. Inst. Oswaldo Cruz 5: 192, Pis. 14-18, 

 Fig. 2, 1913. 



The type species is Proteomyces infestans Moses & Vianna. 



Yeast cells pyriform, germinating by germ tubes which become septate 

 and produce thick-walled chlamydospores or arthrospores. These in turn ger- 

 minate by highly developed hyphae ; colonies cerebriform, vermiculate or fur- 

 rowed, often appearing powdery in the center ; pellicle formed on liquid media 

 (rarely only a highly developed ring) ; no fermentation. 



Isolated from abscesses and ulcers in man, the lesions are usually some- 

 what superficial but spread rapidly and widely. In the absence of sufficient 

 morphologic data, I have assembled here those species with cerebriform or 

 vermiculate colonies, showing no fermentation of sugar, whether gelatin is 

 liquefied or not. It seems quite probable that further work will show that 

 these species belong in Zymonema or in some closely related genus. Several 

 of these species were referred to Candida (Geotrichoides) by Langeron & Talice 

 (1932), but they seem better placed here until more is known of their mor- 

 phology.
