Abstract
For cultivation Sabouraud's and Plaut's media were used, but growth of the fungi was found to be very scanty on both media.They best developed on the serum agar, their first appearance being white moss-like but later of the size of one-sen copper coin with radiating folds and central elevation, having an inclination almost exclusively to deep growth.On gelatin they formed a deposit, were mealy looking and the medium was liquified in the course of 2 months.On potetoes the growth were found to be perpendicularly raised from the culture. They appeared to be bunched, grayish-white in colour and afterward became grayish-yellow.The multiplication of the fungi in the culture took place as in the case of Trichophyton fungus, viz. conidien, chlamydospores or sporangium, spindle spores were observed.From this experiment, it may be said that the fungi are morphologically similar to the Trichophyton fungus, but from the cultural and pathogenic point of view it has a similarity to the favus fungi.For this reason, I believe that the causal organism of this disease is identical with what is termed as Trichophyton faviform album.
