278 MEDICAL MYCOLOGY 



Mycotorula interdigitalis Radaelli apud Flarer, Arch. Ital. Derm. Sifiligr. 

 Venereol. 7: 415-478, 11 figs., 1931. 



Torulopsis pidcherrima var. variahilis Lodder, Anaskosporogenen Hefen 1: 

 144-146, 1934. 



Isolated from interdigital lesions. 



Cells mostly spherical 3.5-4/a in diameter, thin-walled, uniguttulate. Older 

 cells spherical or ellipsoid 6-8.5 x 5.5-7/a, single or in pairs, thickrwalled. Pro- 

 toplasm at first homogeneous and granular, later vacuolate, blastospores some- 

 times solitary, sometimes in verticils about cylindric septate hyphae, 2-3.5/a in 

 diameter, sparingly branched. 



On Pollacci agar, colonies punctiform, moist, creamy, yellowish. Flarer 

 reports colony dense, creamy, whitish, shining; margin smooth, regular, and 

 confluent; slightly grayish when old. On malt agar, colony yellowish, shining, 

 slightly radially striate, margin smooth. On malt gelatin, colonies irregularly 

 reddish, flat, smooth, radially striate, margin sinuous. On malt extract, a 

 thin ring and thin, slimy pellicle which soon sinks, slight odor of esters. On 

 broth, an incomplete ring with a cottony, floccose sediment. On alcohol, a thin 

 pellicle. Glucose, fructose, and mannose fermented. Gelatin liquefied in 75 

 days. 



Syringospora cutanea Dodge, n. sp. 



Mycelohlastanon cutanenm var. Takahashi, Jap. Jour. Derm. Urol. 29: 224- 

 251, 318-331 [26-31], 1929. 



Isolated from mycosis of interdigital spaces as well as of gluteal, perianal, 

 inguinocrural, and axillary folds. In one case, isolated from neck of infant. 



Yeast cells ovoid or ellipsoid, 2-4 x 3-5/*, granular at first, becoming vacuo- 

 late and thick-walled. Mycelium 2-5/* up to 50/*, septate. Mycelium forma- 

 tion is stimulated by the following factors : lowered temperature, high oxygen 

 tension, slight acidity of substrate, depletion of nutrients, addition of carbo- 

 hydrates, especially glucose, addition of "koji, " growth on carrot, on man, 

 or other mammals. Blastospores appear at the septa, often in dense clusters 

 suggestive of a mulberry. No asci formed. 



Colony on malt agar or Sabouraud glucose is brownish white, smooth, 

 shining and creamy, with the margin showing dendroid projections of my- 

 celium into the medium. On broth, producing a slight turbidity, ring, sedi- 

 ment, but no pellicle. Growth better on glucose broth. Glucose, maltose, 

 fructose, mannose fermented, but not sucrose, galactose, raffinose, dextrin, lac- 

 tose, or mannite. Gelatin not liquefied, though dendroid mycelium appears 

 along the stab. Malt gelatin slowly liquefied. Milk acidified and coagulated, 

 the optimum temperature for this being 37° C. 



Syring"Ospora Tonge (Mattlet) Dodge, n. comb. 



Monilia Tonge Mattlet, Ann. Soc. Beige Med. Trop. 6: 22, 23, 1926. 



Isolated from cases showing sjonptoms of true dysentery and of enteritis. 

 No amoebae or cysts found. Patients natives of Belgian Congo. Ameliora- 

 tion of symptoms and even cure on treatment with light purgatives in con- 

 junction with emetine injections.
