Abstract: A method for incubating fruiting bodies of Antrodia cinnamomea is disclosed. The method comprises steps of: (a) obtaining a hymenium slice from a fruiting body of Antrodia cinnamomea; (b) transferring the hymenium slice to a selective culture medium for incubation to obtain an isolated strain; (c) transferring the isolated strain to a bagasse culture medium for incubation; (d) subjecting proliferation by liquid culture or solid culture to obtain large-scale liquid spawn or solid spawn; (e) inoculating a wood segment with the liquid spawn or the solid spawn and subjecting incubation; and (f) re-inoculating the wood segment with mixed single-spore colonies of Antrodia cinnamomea and subjecting incubation until fruiting bodies are produced.
