found in donkeys, and may infect man. The same or similar 

 species are found parasitic on the horse and on some birds, and may 

 also infect man. 



Ectotrichophyton ochraceum Sabouraud, igog. 



Synonym. — Trichophyton ochraceum Sabouraud, igog. 



Type Ectothrix, of animal origin; cultures somewhat similar to 

 favus. On maltose and glucose agars the colonies are character- 

 ized by an ochre-yellow knob ; portions of the growth may be covered 

 by an extremely short, almost invisible, duvet. On ordinar}^ agar 

 the surface of the colonies is cerebriform. Optimum temperature, 

 25° C. It is easily inoculated into guinea-pigs. 



Ectotrichophyton album Sabouraud, igo/. 



Synonym. — Trichophyton album Sabouraud, igo7. 



The cultures are extremely like favus, but are generally less 

 bulging, more deeply umbilicated, and more regularly folded; 

 the growth deepens in the medium; some white duvet present. 

 Optimum temperature, 25° C. Can be inoculated into guinea-pigs. 



Ectotrichophyton discoides Sabouraud, igog. 



Synonym. — Trichophyton discoides Sabouraud, igog. 



Endo-ectothrix, megalosporon, faviform. Somewhat similar to 

 E. album, but the growth, which is almost a perfect disc, has a 

 more flattened surface. There is often a central knob. The whole 

 growth has a brownish-yellowish colour, with a moist surface, 

 somewhat resembling the non-pigment ed cultures of Trichophyton 

 violaceum. It occurs in Egypt and in the Anglo-Egyptian Sudan, 

 as described by one of us. 



Ectotrichophyton luxurians Brault and Viguier, igi4. 

 Isolated from cases of kerion in Algeria. Very rapid growth with 

 faviform appearance. 



Ectotrichophyton (Microtrichcphytcn) Castellani and 

 Chalmers, igi8. 



Definition. — Ectotrichophyton with small spores 3-4 microns in 

 diameter.
