Charles. I have not used corn stalks for oyster mushrooms myself but and pretty certain they could make make a good substrate, 0.3% hydrogen peroxide or another low effort treatment might work too. GMO cross contamination of the mushrooms would not be a concern. Also, consider Wine Cap Stropharia (Stropharia rugosoannulata), in eastern Europe they are grown in fields on the corn stubble.
