210 MEDICAL MYCOLOGY 



colony smooth and flat with slightly dentate margin. On beet and potato, 

 colony cream-colored with broad convolutions, quickly becoming white and 

 powdery. In agar and Loeffler agar, colony cream-colored with a tough, 

 wrinkled surface. In glycerol solution, both pellicle and sediment formed, the 

 liquid remaining clear. On maltose broth, a thick pellicle with broad con- 

 volutions appears. Gelatin liquefied and milk coagulated. No indol. Survives 

 exposure to a temperature of 80° C, for one-half hour but is killed after one 

 hour at this temperature.

Isolated from the blood of a patient with papules and pustules forming 

 extensive confluent ulcerated areas, originally described clinically as ''pseudo- 

 bromuride" by Brocq, Pautrier and Fernet. Probably the lungs were also 

 involved, as this organism was regularly found in the sputum. Healed promptly 

 on treatment with potassium iodide. 



Cells cylindric, 10-15 x 4-5/x, hyphae little branched, forming arthrospores. 

 Chlamydospores ovoid, fusiform or pyriform, walls thick, yellowish. 



On Sabouraud agar, colony at first a viscous mass, then firmer, shining, 

 reticulate wrinkled to vermiculate, at first white, then cream-colored, yellow, 

 brown or chocolate. On Sabouraud conservation agar, growth very slow, colo- 

 nies not over 3 cm. On potato, colony brown, soft. On carrot, growth better, 

 lighter, drier, with more aerial mycelium. On serum, colonies white, flat, 

 poor gi'owth, no change in medium. On blood agar, growth slow. No growth 

 on ascitic fluid. Growth slight with slight acidity on litmus milk. On peptone 

 maltose broth and other liquids, no pellicle but the ring is highly developed. 

 Sugars not fermented. Gelatin slowly liquefied after some time. 



It is possible that this species is synonymous with the following which 

 antedates it. However, P. asteroides has been so briefly described that I dislike 

 to reduce P. Brocquii to synonymy without further study.

Lesions (probably contracted from a calf) appearing on beard and neck 

 of man. Lesions infiltrated, elevated 1-1.5 mm., round or oval, confluent, 

 swollen, soft, exuding brownish yellow secretion. Pathogenic to guinea pigs, 

 rats, and mice.
