MALASSEZIA 359 



ment settling, indol produced. Acid is formed in lactose broth. Litmus milk 

 clotted in 2 days, decolorized and peptonized in 10-20 days. Gelatin liquefied. 



The organism cultivated and studied by Kambayashi (1932) is described 

 as follows : 



Spores mostly ovoid or elongate ovoid, 5-6 x 4/^., occasionally nearly 

 spherical in liquid media. Hyphae short, either pointed or rounded ends, 

 2.4-2. 6/i in diameter, straight or partially curved. In much older cultui-es, 

 hyphae longer, richly branched, abjointing the ends of short lateral branches 

 on a slightly differentiated conidiophore. Conidia sometimes in short chains 

 of 2-3 cells, 3-5-6 x ifx. 



On Sabouraud, growth of primary culture very slow, about 9 months to 

 produce a colony the size of a rice grain, whitish yellow, slightly verrucose. 

 The first subculture attains about this size in 20 days. Colonies yelloAvish 

 white, confluent, surface grooved and knotted, with a tendency for super- 

 ficial grooves to be radial at the margins. The yellow of the young colony 

 becomes lighter to grayish, then with age the yellowish color reappears and 

 passes on to brown. Colony at first moist, becoming dryer and more chalky. 

 The giant colony is a conical mass, about 3.5 cm. in diameter, with fine irregu- 

 lar radial folds cut irregularly by cross or circular folds, mostly moist, some- 

 what shining, margin whitish gray, central mass 1.5 cm. high. 



A study of the authors' figures seems to show a conidiophore suggesting 

 an Acremonium or, in some cases, even a suggestion of Verticillium or Clado- 

 hotryum. 



The fact of the very long time of incubation and the fact that the colonies 

 occurred near the edge of the plate suggest that the fungus described may 

 be a contaminant. This work needs further confirmation.
