<p>Studies of the EtOAc extract of the culture broth and methanol extract of the mycelium of <i>Stereum insigne</i> CGMCC5.57 led to the isolation of one new dihydrobenzofuran (<b>1</b>) and six known compounds (<b>2</b>–<b>7</b>). The structures of compounds were elucidated mainly by HRESIMS experiments, and 1D, 2D NMR spectroscopy analysis. This is the first report about the chemical constitutes of the fungus <i>S. insigne</i>.</p
