EREMASCACEAE IMPERFECTAE 219 



waxy, and spreading. On malt gelatin surface growth is white, slightly raised 

 and shining, gradually sinking into gelatin, forming a funnel-shaped depres- 

 sion. Giant colony on malt gelatin round, shiny with raised margin showing 

 concentric ring halfway from center to edge, slight radiate markings. In 

 malt extract, there is formed a thin film and ring with flocculent turbidity 

 in the liquid and heavy sediment. Very slight growth under olive oil. No 

 fermentation of any sugar. Acid with ring formation and turbidity, clearing 

 about the tenth day, in glucose, mannose, galactose, fructose, and sucrose (no 

 ring in glucose). In other sugars growth similar, but no aciditj'" and no ring 

 formation in glycerol and inulin. Sucrose inverted. Milk not coagulated, 

 slight alkalinity in 115 days. Gelatin slightly liquefied in 29 days, completely 

 in 116 days.

Originally isolated from cases of bronchitis and tonsillitis in Ceylon. 

 ?Isolated from cases of thrush by Pijper (1917) in South Africa. 



Colony yellowish amber, or brownish, surface crinkled, almost vermicu- 

 late. No fermentation, slight acid produced on glucose, fructose, maltose, and 

 galactose. Castellani states no action on milk, gelatin slowly liquefied. Pijper 

 states that gelatin and serum were not liquefied by his strain, milk rendered 

 acid, and slightly clotted and peptonized. It is possible that Pijper 's organism 

 was Mycoderma pararugosum instead of this species. 



Geotrichum iimnite (Castellani) Agostini, Jour. Trop. Med. Hyg. 35: 266- 

 269, 3 figs., 1932.

Isolated by Castellani from a ease of "blastomycosis,'' authentic cultures 

 studied and described by Agostini. 



Mycelium slender, hyaline, 2-2. 5/a in diameter, not branching, often uniting 

 in fascicles, later mycelium thicker, 3-5/t, with cylindric arthrospores 6-9/a, 

 racquet mycelium present. Large chlamydospores rich in fat globules, present. 



Colonies on Pollacci agar, white, fluffy, powdery, adherent to the surface, 

 becoming slightly yellowish brown. Growth similar on carrot and potato. 

 On mannitol agar, colonies dark brown to black with pigment diffusing into 

 the medium. Glucose and maltose not fermented, milk not coagulated. No 

 growth on blood agar. Gelatin and serum rapidly liquefied. Optimum tem- 

 perature 22°-27° C. 



From the description of the organism given by Agostini, it is quite evi- 

 dent that this organism is not related to Coccidioides immitis and that the 

 synonymy quoted by her is incorrect. While Castellani does not state, it is
