Abstract: Provided is an agent for promoting growth of nonpathogenic oral indigenous bacteria, or an agent for improving oral bacterial flora, which comprises the dry powder of one or more mushrooms selected from the group consisting of Hericium erinaceus, Grifola frondosa, Lyophyllum shimeji, Hypsizygus marmoreus, Pleurotus ostreatus, Agaricus blazei, and Lentinula edodes, or an extract thereof, and which has an excellent growth-promoting effect on nonpathogenic oral indigenous bacteria and an excellent improving effect on oral bacterial flora, and which is effective in maintaining balanced indigenous bacterial flora. Also provided is a composition for oral use containing same.

Abstract: The object of the invention is to provide a method for developing a novel species by means of interspecific crossbreeding among P. eryngii (DC.:Fr.) Quel., P. eryngii (DC.:Fr.) Quel. var. elaeoselini, P. eryngii (DC.:Fr.) Quel. var. tuoliensis C. J. Mou and P. nebrodensis (DC.:Fr.) Quel., which are not native in Japan, and P. ostreatus (Jacq.: Fr.) Kummer, which is native in Japan and the novel species obtained by the method and is also to provide a novel species of Pleurotus spp. carrying both a P. eryngii (DC.:Fr.) Quel. gene and a P. ostreatus (Jacq.: Fr.) Kummer gene by crossbreeding P. ostreatus (Jacq.: Fr.) Kummer with P. eryngii (DC.:Fr.) Quel. var. tuoliensis C. J. Mou, P. nebrodensis (DC.:Fr.) Quel. or P. eryngii (DC.:Fr.) Quel. var. ferulae Lanzi, thereby obtaining a strain capable of further crossbreeding with P. eryngii (DC.:Fr.) Quel., P. eryngii (DC.:Fr.) Quel. var. elaeoselini or the like.

Abstract: The present invention relates to new, distinct horticultural varieties of mushroom plant of the species Pleurotus eryngii. The new varieties, named ‘PLE-3’ and ‘PLE-5’, was found by crossbreeding eryngii varieties having dominant traits. The varieties are featured by its presentable carpophore, delicacy, stability and uniformity and pronounced distinguishability.

Abstract: A new and distinct variety of mushroom plant of Bunashimeji mushroom, Hypsizigus marmoreus, names “Hokuto-18”, is cultivated by gathering and repeated breeding of fungal strains having dominant traits. This new and distinct variety has good qualitative character and appearance, good keeping quality and storage life and delicious tasting and is exquisite in stability, reproducibility and uniformity when being produced.
