Recently a JPC=0++ [X(1812)] state with a mass near the threshold of \ensuremathω and \ensuremathφ has been observed by the BES collaboration in J/\ensuremathψ\ensuremath→\ensuremathγ\ensuremathω\ensuremathφ decay. It has been suggested that it is a IG=0+ state. If it is true, this state fits in a mixing scheme based on quarkonia, glueball, and hybrid (QGH) very nicely where five physical states are predicted. Together with the known f0(1370), f0(1500), f0(1710), and f0(1790) states, X(1812) completes the five members in this family. Using known experimental data on these particles, we determine the ranges of the mixing parameters and predict decay properties for X(1812). We also discuss some features which may be able to distinguish between four-quark and hybrid mixing schemes.
