EREMASCACEAE IMPERFECTAB 209 



Isolated from spontaneous blastomycosis of a white rat. 



Cells ovoid, guttulate, or ellipsoid, but often variously shaped, 4.5 x 5/a or 

 5 X S/A up to 4.5 X 8/A, in malt extract forming a septate mycelium, 2-2.5 x 

 12.2/A. No ascospores. 



Giant colonies in must gelatin round, verrucose, rose. No fermentation, 

 no coagulation of milk. 



The strain referred by Lodder (1934) to Bhodotorula pallida Lodder was 

 evidently a contaminant. 



Proteomyces brocianum (Pinoy) Dodge, n. comb. 



Mycoderma brocianum Pinoy apud Anderson, Colas-Belcour & Broc, Arch. 

 Inst. Pasteur Tunis 19: 317-322, 1930. 



Isolated from ulcerous lesions on the back of the hand. Not pathogenic 

 to experimental animals. 



Hyphae septate ; arthrospores 4.5 x 3.5//,, thin-walled, no conidia. 



Colonies on Sabouraud glucose agar at 37° C. creamy white with fine 

 filamentous radiations on the surface with rose color visible on the fifth day 

 and more marked the fourteenth day, becoming somewhat cerebriform in age. 



Fig. 41. — Proteomyces infestans. (After Moses & Vianna 1913.) 



Colonies on gelatin similar. On potato, similar but reddish orange, only 

 slightly folded at the center. On carrot, color remains rose. In potato de- 

 coction, sediment, no pellicle, liquid clear. Acid formation with maltose, 

 sucrose, and glucose, none with lactose. Gelatin not liquefied. 



Proteomyces infestans Moses & Vianna, Mem. Inst. Oswaldo Cruz 5: 192, 

 Pis. 14-18, Fig. 2, 1913. 



Sporotrichum infestans ? Sartoiy, Champ. Parasit. Homme Anim. 655-656, 

 1922. 



Mycoderma infestans Fonseca & Area Leao, Brasil Med. 43: 667, 1929. 



Isolated from hard, deep-seated abscesses on the extremities Avhich become 

 edematous, and the temperature rises to 39°-40° C. Pathogenic for guinea 

 pigs and rats. 



Mycelium septate, cells elongate, not easily separating into arthrospores. 

 Blast ospores pyriform, lateral, borne singly, chlamydospores terminal (Fig. 41). 



Growth on Sabouraud maltose agar good, bright brown, cerebriform sur- 

 face in 3-4 days, later the periphery with radial folds. On Sabouraud glucose, 

 colony cream-colored, elevated, cerebriform. On Sabouraud conser^'ation agar,
