Abstract
Three edible mycorrhizal mushrooms, Tricholoma portentosum, T. saponaceum, and T. terreum, that had formed ectomycorrhizas with Pinus densiflora seedlings in vitro, were maintained in open pot culture for 3 years under laboratory conditions. Tricholoma portentosum and T. saponaceum produced fruit bodies several times. For T. terreum, which produced a single fruit body in the third year, this is the first report of mushroom production under controlled conditions. Morphological observation of fruit bodies indicated that they were mature, i.e., well-organized cap, stem, and gills, and basidiospores. These results suggest that cultivation of these three edible Tricholoma mushrooms is feasible.
