Chemical constituents of fungus F03 belonging to Basidiomycota.

Filamentous fungus F03 belonging to Basidiomycota was obtained and identified as Phlebiopsis crassa based on ITS sequence when Morchella. sp was isolated from the wild fruiting body by spores releasing method. Chemical constituents were separated by gel chromatography, HPLC and recrystallization. Structures of compounds were confirmed by NMR data. Four products orsellinic acid (1), α-nigerose (2), uridine (3), N-(4-hydroxyphenyl)acetamide (4) were identified and all compounds were isolated from the genus Phlebiopsis for the first time.
