238 MEDICAL MYCOLOGY 



Monilia de LeDantec Sartory, Champ. Paras. Homme Anim. 709, 710, 1922. 



Isolated from the feces of two sailors ill with nautical beriberi. Not 

 pathogenic on hypodermic injection to mouse, guinea pig, or hen. Intraperi- 

 toneal injection in guinea pig produced peritonitis. 



Growth on glucose agar, thick, creamy, grayish, center thickest, two 

 marginal zones thinner. Surface moist, not velvety but rough with points, 

 suggesting the surface of a stormy sea. Hyphae penetrate agar. No color 

 change on ageing. In Sabouraud media, colonies appear in 24 hours and in 

 48 hours grow onto walls of tube. On potato, colony is gray ; on carrot, colony 

 is white, creamy. On gelatin stab, growth resembles inverted fir tree. In 

 broth, a silky pellicle forms and sinks to bottom, liquid is cloudy. In glucose 

 broth, there develop an ethereal odor and acid reaction which in about 8 

 weeks give way to fetid odor and alkaline reaction. In peptone broth, the 

 fragile pellicle soon sinks while another forms, wide ring, liquid turbid and 

 of fetid odor. In milk, a pellicle forms, soft curd, acid at first, and then 

 alkaline and fetid. Glucose and mannite fermented, lactose slightly, maltose 

 and sucrose not at all. Milk coagulated. Gelatin liquefied in 25-30 days. 

 Growth slow under anaerobic conditions. 



Doubtful Position 



The following species, perhaps saprophytes, isolated from cases of lingua 

 nigra pilosa, may belong here but are too poorly described for certain deter- 

 mination. 



Oospora catenata Schaede, Derm. Woch. 98: 521-527, 1934. 



Isolated from lingua nigra pilosa. 



Mycelium G-l/x in diameter, cells ellipsoid, 6-8.5 x 8-15/i, or spherical 8-10/x 

 in diameter, clinging together in short chains. 



Colonies on malt agar dull, glassy white with slight grayish tinge, some- 

 what rough. On carrots, colonies thick white, also on liquid media. 



Oospora fragilis Schaede, Derm. Woch. 98: 521-527, 1934. 



Isolated from lingua nigra pilosa. 



Mycelium 6/^ in diameter, easily separating into single cells. Ellipsoid 

 cells 5-8 X 7-13. 5/x, spherical cells 5-7ix in diameter. 



On malt agar, colonies white, powdery, smooth; colonies thinner on car- 

 rots and on liquid media. 



PARENDOMYCES 



Parendomyces Queyrat & Laroche, Bull. Mem. Soc. Med. Hop. Paris III, 

 28: 111-136, 1909. 



The type species is Parendomyces alhus Queyrat & Laroche. 



Colony creamy, mycelium scanty, limited to short chains in liquid media, 

 cells ellipsoid; chlamydospores abundant; no ascospores. Pellicle formation 

 rare, rings more common on liquid media, gelatin not liquefied, sugars not 

 fermented.
