Trametes Cingulata berk. In culture

Summary

1. Growth characteristics ofTrametes cingulata Berk. have been studied in culture under different environmental conditions.

2. Basidiospores from freshly taken fructifications have been found to germinate very quickly on agar medium under ordinary conditions of diffused light and temperature (30° C.) of the laboratory. Basidiospores always germinate by means of a single germ-tube.

3. Being a ‘white rot’ fungus, it gives positive reaction to Bavendamm’s oxidase test.

4. The fungus has been grown on 2·5%malt-agar medium with seven different grades of pH, three on either side of the neutral. The best growth has been found in the medium having neutralpH value. An interesting feature is the wide range of tolerance of the fungus to both acidic and alkaline conditions to a certain extent.

5. Cultural characteristics of the fungus have been studied on four different media under a set of constant conditions. Best growth has been obtained onpotato-dextrose-agar, lesser inmalt-agar, thenCzapeck’s synthetic-agar andwood-decoction-agar following in succession.
