In this paper I shall present a study of the gross morphologic variations of a representative group of pathogenic fungi grown on mediums in which the percentages of Difco dextrose and Difco peptone, tryptone or proteose peptone have been varied. I shall also discuss certain features of mediums and their constituents on which I feel not enough stress has been placed in previous studies.
In 1877 Grawitz1 reviewed the subject of medical mycology and contributed observations of his own. Duclaux2 and Feulard3 added important information on this and related subjects. In 1887 Verujski4 discussed different culture mediums and emphasized the importance of reaction, humidity and temperature. He described the nourishment of mycelia as taking place by capillarity (surface tension). He used both liquid and solid culture mediums. In 1921 Weidman and MacMillan5 discussed at some length the relative value of American and French products
