718 MEDICAL MYCOLOGY 



Colonies green, ranging- in shade from that of pistachio to dark green or 

 almost black. Pigment diffusing. Good growth on gelatin and agar, convex, 

 adherent, margin finely lacy ; colony dirty white at first, later becoming green. 

 In broth, no turbidity or pellicle, although floating colonies form and settle. 

 Milk colored green and coagulated. On potato, colonj^ whitish, medium be- 

 coming very dark violet. 



Actinomyces panginensis (Froilano de Mello & St. Antonio Fernandes) 

 Dodge, n. comb. 



Nocardia panginensis Froilano de Mello & St. Antonio Fernandes, Mem. 

 Asiatic Soc. Bengal 7: 130, 1919. 



A saprophyte isolated from a dermatosis. 



Cells 40-60 X 0.8-1/a. Gram-positive, not acid-fast. 



On agar, colony white, opalescent, dry granular, margins regularly den- 

 tate, efflorescence white. On sugar agars, better developed, yellowish. On 

 potato, colony cinnabar red in the center with white margin, becoming brown- 

 ish yellow and greenish, medium dirty brown. On broth, pellicle white, ad- 

 herent, folded, turbidity and sediment present ; efflorescence white. Milk 

 coagulated and digested, litmus decolorized. 



The following organism, incompletely described, perhaps belongs here. 



Actinomyces sp. Bumier & Duche, Bull. Soc. Fran^. Derm. Syphiligr. 40: 

 581, 1933. 



Isolated from a case of superficial eczema, dry, scaly, yellowish red on 

 face, scalp, behind ear, and in inguinoscrotal, abdominal, and genital folds. 



Strictly aerobic, gelatin liquefied, efflorescence early, white, abundant; 

 odor moldy; slight red pigment on glucose, peptone, or asparagin media.

Nocardia rubra Chalmers & Christopherson, Ann. Trop. Med. Parasitol. 10: 

 265, 1916. 



Actinomyces ruber Sartoiy & Bailly, ]\Iycoses Pulmonaires, 252, 1923. Not 

 Actinomyces ruber Krainsky, 1914, nor Nocardia KrainsMi, Chalmers & Chris- 

 topherson, Ann. Trop. Med. Parasitol. 10: 268, 1916. 



Isolated from sputum. Nonpathogenic to laboratory animals. 



Sporulation on the fifth day, spores spherical. 



On glycerol agar, colony bright red and superficial. On peptone agar, 

 also bright red, granular, dry, rugose, not adherent. Colonies on potato red, 

 spreading rapidly. In broth and milk, red colonies form at the surface and 

 sink to the bottom. Coconut milk becomes turbid, but remains colorless. 

 Gelatin is liquefied, without pigment formation. White pellicle also formed.
