EREMASCACEAE IMPERFECTAE 225 



sediment. Alkali fonned on Endo's medium. Granular soapy pellicle on arabi- 

 nose. No fermentation of sugars but slight acid formation with maltose, 

 rhamnose, arabinose. No action on inulin, lactose, and mannite. Milk not 

 coagulated and no acid formed. Gelatin not liquefied.

Monilia Caoi Castellani & Chalmers, Man. Trop. Med. ed. 2, 831, 1913.

Oidium 22 Cao, Zeitschr. Hyg. 34: 317-318, 1900. 



Isolated from a case of chronic bronchitis in an old man. Pathogenic to 

 rabbits. 



Cells large, hyphae long and little branched. 



Colonies on agar yellowish, granular, elevated with radial strands at 

 margin. On potato, growth abundant Avith irregular margins, granular, yel- 

 low with surface of potato browned. Star-shaped colonies on gelatin surface, 

 inverted fir tree growth along the stab. No fermentation of sugars. No 

 change in milk. 



Mycoderma paranigosum (Castellani & Douglas) Dodge, n. comb. 



Hemispora pararugosa Castellani & Douglas, Jour. Trop. Med. Hyg. 24: 

 149, pi. 1, 1921. 



Isolated from sputum, no fever, cough with mucopurulent expectoration, 

 with no blood in mild type of cases. In severe type, cases resemble phthisis, 

 patient emaciated, hectic fever with blood in expectoration; often develop- 

 ing after severe tonsillitis, with yellowish gray patches. Physical examina- 

 tion revealed patches of dullness, fine crepitation, and pleural rubbing. 



No fermentation or acidity with sugars, no action on milk, gelatin not 

 liquefied. 



It is quite possible that the organism described by Pijper (1917) from 

 South Africa under the name Monilia rugosa (p. 219) should be referred here, 

 although it differs in minor characters. 



Mycoderma Muyag-a Mattlet, Ann. Soc. Beige Med. Trop. 6: 28-29, 1926. 



Isolated in cases presenting symptoms of true dysentery and enteritis in 

 natives of Belgian Congo. No amebas or cysts present. Medication with 

 intramuscular injections of emetine and administration of mild laxatives gave 

 amelioration of symptoms. 



In potato decoction, hyphae septate, branched, 2.5-7^, narrowed at the 

 septa. The young, slender hyphae are rich in protoplasm and contain few fat 

 droplets, few or no septa. Secondary hyphae arise near, but not at, transverse 

 walls. In older hyphae the positions of rupture are forecast by the condensa- 

 tion of protoplasm about the fat droplets without thickening of membrane. 

 Arthrospores nearly spherical, not thick-walled. Optimum temperature 22°- 

 25° C. 



On Sabouraud agar at 37°, colony creamy yellow, margin of radiating 

 hyphae, adherent to the medium with radial folds. At 25°, colony covered
