542 MEDICAL MYCOLOGY 



"While this species may occur on the scalp, it seems to prefer the glabrous 

 skin in man, even producing kerions. On the cat, numerous large, glabrous 

 crusted areas appear, accompanied by pruritus and apparently spread by 

 scratching. Inoculation into cat, dog, and guinea pig positive. Common in 

 England, Belgium, Northern Italy, rare in Budapest, Australia, New York, 

 and Canada. Reports from the states of Rio de Janeiro, Minas Geraes and Sao 

 Paulo in Brazil, from Uruguay and from Argentina should probably be referred 

 to M. fulvum. 



Closterospores as in M. canis, but slightly smaller, 8-10-celled ; chlamydo- 

 spores 4-7/a; pectinate hyphae and compound thyrses of aleurospores present. 



Colonies regular flat discs without foldings or elevations, except the small 

 central button, grayish velvety, soon covered with a chamois or yellowish 

 tobacco (Havana) color at the disc; margin wdiite, of fine radiations. Pleo- 

 morphism covers the colony with a white velvet. Grows on potato, with a 

 thin white velvet. 



From Ballagi's description of his M. fulvum (central umbo surrounded 

 by a rust broAvn zone, often with concentric circles, margin woolly, white; 

 on potato, colony fox red), it seems likely that his cultures should be referred 

 to M. felineum.

present.
