a short white velvet. Gelatin very slowly liquefied. No fermentation or acid 

 production with sugars. The white velvet is more abundant on alkaline 

 media, the colony moister on acid media. 



Ota & Kawatsure who received cultures from Castellani were unable to 

 distinguish this species from E. concentricum.

Isolated from tinea imbricata and said to be the commonest species in

On 4% glucose agar, growth abundant, surface cerebriform or crinkled, 

 slight amber in color, becoming deeper in age, velvet absent or very slight. 

 On Sabouraud agar, growth scanty, light gray, mostly submerged, with a 

 central knob with projections deepening in medium, no velvet. Other sugar 

 media similar to glucose agar. Gelatin slowly liquefied, slight growth on milk, 

 no fermentation. 



Most recent authors, as Langeron & Milochevitch (1930) and Ota & 

 Kawatsure (1931), have regarded this a synonym of E. concentricum.
