Interspecific heterokaryons were obtained between auxotrophic mutants of Pleurotus ostreatus and Pleurotus florida by polyethylene $glycol-Ca^{++}$ induced fusion of somatic protoplasts. The fusion products produced colonies of dense growing mycelium after 10-14 days culture on hypertonic Mushroom Minimal Medium. When they were transferred to Mushroom Minimal Medium plates, the sectors showed normal vegetative morphology but the colonies of irregular shape varied in growth rate. All of the colonies produced fruit body of normal pilei. Some heterokaryon colonies bearing none or only a small amounts of basidiospores were isolated. Fusion products, generally, gave higher basidiocarp yields than the parents.

Isoprenoid quinone are essential compositions of the respiratory or photosynthetic electron transport system of microorganisms. Their chemotaxonomic significance as well as their physiological importance has been fully realized. We determined the ubiquinone types of the genus Trichoderma, Gliocladium, Verticillium, Aspergillus, and several mushroom such as Agaricus bisporus. Lentinus edodes, Pleurotus ostreatus, Flammulina velutips, Phellinus chrysoloma, Phellinus igniarius and Phellinus laevigatus. Most of Deuteromycotina had Q-10($H_2$), and all of mushroom had Q-9 as main ubiquinone type. Ubiquinone type in other fungal taxa.
