An isolate of Lepista nuda was cultivated on the solid media consisted of various cereal grains or those of the acacia sawdust mixed with other cereal grains. The mycelia grew well on the solid cultures made from millet cereals, but did not on those from sorghum or corn cereals. Thus, the millet and the acacia sawdust, as the solid media, were employed for the next experiments related to mycelial growths. For growth of this isolate, it was shown that the nitrogen source is needed for those of millet. Also, the rice bras or minerals were considered to be needed for the acacia sawdust. As minerals, however, the rice bran is shown as the best additive in the solid cultures of the acacia sawdust. The mycelia of L. nods were cultivated directly through the solid cultures. Their growths were measured by the production of carbon dioxide with gas chromatography.
