| Outline of Final Research Achievements |
Mushroom poisoning caused by Tricholoma equestre developed fatal rhabdomyolysis both in France and Poland. The T. equestre is a synonym of T. flavovirens known to distribute in Japan. In order to study the toxic principle of this mushroom, discrimination of this fungus from some similar species is essential.
For this purpose, the most complicated problem is absence of definite morphological information of each resembling fungi distribute in Japan. On investigation of possible Tricholoma species, discrimination of the following three yellow species, T. flavovirens, T. auratum, and T. aestuans was turned out to be the critical point. A kind of the host trees helps the discrimination, that is, T. auratum and T. aestuans grow in a coniferous forest, on the other hand, T. flavovirens do not depend on coniferous trees and grows in a broadleaf forest. Taste of the carpophore is another clue, that is, T. aestuans has a bitter taste and then produce a sharp taste on chewing.
