It resembles Yorkshire Fog. It differs in that the glumes of Annual Fog are awned with an awn at least a millimetre long (and up to 5mm long). Yorkshire Fog is awnless, or with a short awn less than a millimetre long. The leaf blades, the glumes and (usually) the stalks are hairy. As with Yorkshire Fog, the flowers are clustered into a more or less egg-shaped cluster.
It is an environmental weed.
