(r) Lactarius laeticolor (Oct 2012, Matsumoto, Nagano). In Japan, T. auratum and T. flavovirens are often confused in the taxonomy, but both have been commonly used since the old era. In B. edulis, several related species such as B. reticulatus, B. violaceofuscus W.F. Chiu, and B. hiratsukae Nagas. are known in Japan and used as edible mushrooms in common. Suillus orientalis was recently described as a new species, divided from the S. grevillei complex.

      Forty years of harvest records for Tricholoma matsutake fruiting bodies at the Toyooka experimental site in Nagano Prefecture (Fig. 17). While the harvest of fruiting bodies in the control plot decreased significantly throughout the experimental period, the harvest remained stable in the managed plot. This graph was redrawn based on the original data from Furukawa et al.[70]. In 2024, the number of harvested fruiting bodies in the managed plot was nearly equal to the number in 2010 (Hitoshi Furukawa, personal communication).
