terial growth, favor the growth of these yeasts. It has been reported 

 that in samples of 3 per cent boric acid solutions purchased from 

 pharmacies, from 48 to 38,400 pink yeasts per milliliter were obtained 

 by plating! Out of thirty-seven strains of Rhodotorula studied by 

 Lodder, twelve representing seven species and varieties were isolated 

 from human or animal pathological materials, but it is doubtful that 

 any of these was the causative agent of a disease. Thirteen species 

 and varieties of yeasts which would be diagnosed as Rhodotorula 

 have been listed by Dodge * in his Medical Mycology. 



LITERATURE 



Except for the Candidoideae the morphology and taxonomy of the yeasts has 

 been fairly well covered by the monographs of Guilliermond,'' Stelling-Dekker,^^ 

 and Lodder.i^ Henrici ^ has made a sm-vey of recent work up to 1941 in an 87- 

 page review which, together with the three monographs, is recommended to all 

 students particularly concerned with yeasts. In the interests of conservation of 

 space, only such literature is cited here as was not cited by Henrici in the first 

 edition of this book or in his review.
