Raffinose Agar. — Same appearance as galactose. 

 Inulin Agar. — Same appearance as in galactose and raffinose agars. 

 Adonite Agar. — Cerebrif orm ; surface covered with snow-white duvet. 

 Gelatine. — Very slow liquefaction. 



Litmus Milk.— Yeiy scanty growth. After a time the medium may become 

 separated. 



Various Sugar Broths {Maltose. Lactose, etc.).— Slight growth at the bottom 

 of the tube. No production of acid or gas. 



The annexed table shows at a glance the different cultural characteristics 

 of the two fungi in the principal media.

The above characters are based upon the appearance of cultures kept in 

 the dark at a temperature 80° to 90° F., and without rubber caps. If any of 

 these conditions are altered, the cultural characters are changed. If rubber
