EREMASCACEAE 175 



On koji extract agar, colony thin, milky white, smooth, surface moist with 

 sharp borders, becoming thicker, duller, yellowish white ; on drying', becoming 

 brownish yellow witli an ashy gray powder, mycelium very scarce. On 10% 

 sucrose peptone agar, mycelium produced, colony verinicose and folded. No pel- 

 licle on liquid media, powdery sediment. On sucrose peptone solution, mycelium 

 floating as woolly masses hanging from the ring. By Lendner method, fermen- 

 tation with glucose, levulose, mannose, maltose shows strong acid and gas ; 

 dextrin and galactose show slight acid and gas, soon disappearing; no action 

 on other sugars tried. Growth better at 37° C, than at 25° C. ; growth pos- 

 sible in ice box or at 40°. 



Zymonema bonaerense (Greco) Dodge, n. comb. 



Endoniyces bonaerensis Greco, Argentina medica 1908 ; Origine des Tumeurs. 

 123-156, 412-421, Figs. 54-68, 225-231, 1916. 



Producing small miliary abscesses and plaques near eye. Pathogenic for 

 rabbit, forming subcutaneous abscesses. 



Yeast cells 4-6 x 2-4/^, ovoid, hyphae mostly 2-4^ in diameter, occasionally 

 much thicker and shorter. Asci 4-12/x spherical, spores 1-2/a. 



Colonies milk-white, shining-, discrete, or becoming confluent. On solid 

 media after about a month, hyphae beg-in to show in the media. No gas but 

 an ethereal odor in some cultures. On Sabouraud agar, growth at 20° and 

 37° white, creamy, a little thicker in the center, with filaments at the periphery. 

 On beef agar and glycerol agar, growth less, colony flatter, more opaque, less 

 shining white. On potato, colony creamy, very moist, white, later more opaque 

 and grayish. On drying, small secondary yeast colonies form on surface of 

 mother colony. Potato glycerol shows better growth, dryer, mammillate or 

 slightly crateriform, slightly yellowish and cheesy in appearance, medium 

 darkened. On carrot, colony creamy, spreading, white margin toothed. On 

 liquid media no discoloration of media, no pellicle, but sediment produced. 

 Sugars not fermented. Milk coagulated very slowly. Colony on gelatin stab 

 resembles a test tube brush, without radial filaments, no liquefaction. 



The figures and description are not altogether convincing as to presence 

 of ascospores, and I have hesitated to transfer it to this genus, but it is quite 

 evidently not Endoniyces. 



Zymonema album, Dodge, n. sp. 



Monilia sp. Bianchi & Niilo, Bol. Inst. Ch'n. Quirurg. Univ. Buenos Aires 

 4: 531-538, 6 figs., 1927. 



Producing bronchomj^cosis. Pathogenic for guinea pig. 



Spherical yeast cells about Sfi in diameter; ovoid cells 3-5 x 2/*. Cells 

 10-12;u, in diameter, thick-walled with four deeply staining bodies which may 

 be ascospores. In old cultures on glycerol, carrot, and potato, there are slender 

 mycelium and large chlamydospores. This mycelial form continues on sub- 

 culture. 



Colonies hemispheric, creamy white, moist, finally becoming confluent with 

 a dryer, whiter margin. Optimum temperature 37°, but fair growth at 20° C.
