The structure of oscillatory convection in the layers below the umbral photosphere is discussed. A linear stability analysis of a model problem describing a polytropic layer with a vertical magnetic field shows that when the Alfven speed and sound speed are comparable oscillatory convection has a mixed character exhibiting properties of fast and slow magnetoacoustic waves. The analysis reveals that in this regime overstability is possible even in convectively stable layers. The nature of the destabilizing mechanism is discussed.
