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

The present invention relates to new, distinct horticultural varieties of mushroom plant of the species. The new varieties, named 'PLE-3', was found by crossbreedingvarieties having dominant traits. The varieties are featured by its presentable carpophore, delicacy, stability and uniformity and pronounced distinguishability.

Mushroom named 'PLE-3'

A new and distinct variety of mushroom plant of Bunashimeji mushroom,, named '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.
