BES Collaboration has recently observed an enhancement near the $\omega\phi$ threshold in the double OZI suppressed decay $J/\psi \to\gamma\omega\phi$. This $\omega\phi$ enhancement is probably due to a new $J^{PC}=0^{++}$ X(1812) state. We discuss a possible assignment that the X(1812) is a $ 1/\sqrt{2}(u\bar u+d\bar d)g$ (or $s\bar sg$) hybrid meson. We suggest further measurements to test these assignments.
