Four edible mushrooms, Panellus serotinus, Lepista nuda, Tricholoma matsutake and Naematoloma sublateritium, have been investigated chemically. Two new sterols, 5α, 9α-epidioxy-(22E)-ergosta-7, 22-diene-3β, 6α-diol (1) and 5α, 9α-epidioxy-(22E)-ergosta-7, 22-diene-3β, 6β-diol (2), have been isolated from Panellus serotinus. Compound 2 was also isolated from Lepista nuda. A new sterol, 3β, 5α, 9α, 14β-tetrahydroxy-(22E)-ergosta-7, 22-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.
