296 MEDICAL MYCOLOGY 



Mycoderma mataleiise Brumpt, Precis Parasitol. ed. 3, 1084, 1922. 



Pseudomycoderma matalense Ciferri, Arch. Protistenk. 71: 436-443, 1930. 



Geotrichum Matalense Castellani, Jour. Trop. Med. Hyg. 35: 278-279, 3 

 figs., 1932. 



Isolated from ulcers and from sputum of cases of bronchitis in the tropics 

 (Ciferri 1930). 



Mycelium abundant on agar, little branched, septate, 2-5/* in diameter, 

 generally 3-4/*, blastospores sprouting, 5-15 x 2-4/i, generally 10 x 3/t, isolated 

 or sprouting to form chains. 



Colony effuse, white on agar and gelatin. On liquid media, producing 

 islets promptly white, cottony above, mucus, yellowish below, finally becom- 

 ing rose violaceous pellicle, practically no sediment. Sucrose not inverted, 

 milk slightly acidified, no fermentation of sugars, no liquefaction of gelatin. 



There seems little to distinguish var. Chapmani Castellani, Jour. Trop. 

 Med. Hyg. 35: 278-279, 1932. 



Pseudomonilia inexpectata (Mazza, Niiio & Egiies) Dodge, n. comb. 



Monilia inexpectata Mazza, Nino & Egiies, Bol. Inst. Clin. Quirurg. Univ. 

 Buenos Aires 5: 284-288, 1930. 



Mycocandida inexpectata Talice & Mackinnon, Reunion Soc. Argentina 

 Patol. Reg. del Norte in Santiago del Estero 8: 164, 1934. 



Isolated from the drops of pus expressed from inflammatory processes in- 

 volving the fingers, particularly around the nails, in a woman, a native of 

 Buenos Aires, Argentina. Ordinary medicaments of no avail. Intraperitoneal 

 injection to guinea pig and mouse produced abscesses. 



On Sabouraud glucose agar at 37° C, or room temperature, in 24-48 hours, 

 abundant growth, colonies cream white, dry in appearance, opaque surface, 

 not adhering to substrate ; after 5 days several colonies about 1 cm. in diam- 

 eter, center smooth, elevated, margins deeply folded. Growth similarly abun- 

 dant on simple agar and broth media. On agar, slight growth in 24 hours. 

 On potato with 8% glycerol, good growth in 24 hours, colony cream-colored, 

 dry in appearance; no pigmentation of medium. On Drigalski-Conradi me- 

 dium, colony grows without modification of medium at first, then slight evolu- 

 tion of gas. On Gougerot gelatin medium, growth good. On coagulated 

 human serum, organism grows Avith digestion of the part of medium disturbed 

 by puncture. In Sabouraud glucose broth, turbidity and sediment, with for- 

 mation of creamy white pellicle which ascends walls of tube. In plain broth, 

 uniform turbidity and sediment after 24 hours. In Raulin's liquid, turbidity, 

 sediment, and pellicle ascending sides of tube. No fermentation of sugars. 

 Acid produced in maltose, lactose, dextrin, and glucose. No indol. Milk 

 coagulated in 24-48 hours. Gelatin not liquefied. 



Indistinctly positive or negative to Gram's stain; with Gueguen's mixture 

 preparation colored intense blue with tiny points of brick red, probably cor-
