%X Fruiting bodies, mycelia and basidiospores of bisporic and tetrasporic strains in Oudemansiella radicata were stained by bisbenzimide (Hoechst 33258) and observed under fluorescence microscope. The results were as follows: Mycelia of the bisporic strain were monokaryotic and had no clamp connection. The monokaryotic probasidium underwent one round of mitosis and produced two nuclei in the basidium. These two nuclei were then separately transferred into two basidiospores, leaving an empty basidium. As a result, each of the two mature basidiospores had only one nucleus. However, most mycelia of the tetrasporic strain were dikaryotic and had clamped connections. During fruiting body development, the two haploid nuclei in the basidium fused and formed a diploid nucleus. Subsequently, the diploid nucleus underwent meiosis and produced four haploid nuclei. These four nuclei were separately transferred into four basidiospores. The mature basidiospore of the tetrasporic strain each had only one nucleus. The possible mechanisms for the formation of bisporic fruiting bodies of Oudemansiella radicata were suggested and discussed.
