This is chocolate tube slime mold. I have never seen it grow on anything other than dead trees before. Your best course of action is to treat with a chlorothalonil fungicide since a copper sulfate fungicide could damage tomatoes. Chlorothalonil can be purchased under brand names Bravo, Echo, and Daconil.
