SACCHAROMYCETACEAE 



313 



On malt extract a slight ring appears. Growth is good at 38° C, but there 

 is none at 44° C. Fermentation of glucose, denied by Dekker (1931). 



Var. tremoniensis (Ota) Dodge, n. comb. 



Deharyomyces tremo7iiensis Ota, Derm. Woch. 78: 284-289, 312-316, 1924. 



Isolated from a case of interdigital mycosis in Dortmund, Germany. 



Morphology same as that of B. Fahrii. Ferments glucose and mannose. 



Debaryomyces Leopold! Ota, Ann. Parasitol. Hum. Comp. 1: 128-130, 1923. 



Saccharomyces neofonnans Leopold, Arch. Gynaekol. 61: 77-120, Pis. 1-6, 

 1900, nonal. 



Blastomyces {Leopold) Sasakawa, Centralbl. Bakt. I, 88: 273, 1922. 



Isolated from carcinoma of the ovary. Originally reported pathogenic to 

 laboratory animals, but is nonpathogenic to guinea pig.

After 24 hours on malt agar, at 25° C, cells are ovoid or spherical, the 

 smaller having a diameter of 3-5/a, the larger 6 x 7/*. Cells solitary or in pairs 

 with a tendency to occur in masses, uniguttulate, chains not observed (Fig. 

 65). After 9 days cells 6-8/a. In 40 days, membrane thickens, oil globules 

 larger and more numerous. Growth on carrot similar. After 9 days on 

 Gorodkova agar, spores appear, asci scarce, but more abundant than in D. 

 Hudeloi, 1-spored. Spores 2-3;u,, usually echinulate, sometimes smooth. On 

 plaster, asci appear in 4 days. Copulation usually heterogamous, but isogamj^ 

 has been observed. 



Giant colonies, after 30 days, show white rays from center with definite 

 margins. In malt extract, brownish white sediment appears in 30 days. No 

 growth at 40° C, feeble growth at 36° C, growth still good at 12° C, and 

 there is still some at 5° C. No liquefaction of malt gelatin in 35 days. Sucrose
