Four edible mushrooms, Panellus serotinus, Lepista nuda, Tricholoma matsutake and Naematoloma sublateritium, have been investigated chemically. Two new sterols, 5 alpha ,9 alpha -epidioxy-(22E)-ergosta-7,22-diene-3 beta ,6 alpha -diol (1) and 5 alpha ,9 alpha -epidioxy-(22E)-ergosta-7,22-diene-3 beta ,6 beta -diol (2), have been isolated from Panellus serotinus. Compou nd 2 was also isolated from Lepista nuda. A new sterol, 3 beta ,5 alpha ,9 alpha ,14 beta -tetrahydroxy-(22E)-ergosta-7,2 2-dien-6-one (3), and compound 2 have been isolated from Tricholoma matsutake. Three new triterpenoids, sublateriols A-C (4-6), have been isolated from Naematoloma sublateritium. The structures of the new compounds were elucidated on the basis of their spectral data.
