The rim of Schumacher forms an eroded ring that is broken along the western side by the flooded crater Schumacher B. There is a low terrace along the northwestern inner wall. The rim is also notched along the eastern side by a pair of outward bulges. The interior floor of this crater has been resurfaced by basaltic lava, and now forms a level, nearly featureless plain. The floor is somewhat darker in the western half, which the albedo in the eastern half matches the surrounding lunar terrain.
Schumacher and Messala are separated by a rough strip of terrain less than 10 kilometers across, and bisected by a pair of small, co-joined craters. The northern member of this pair lies across the southern rim of Schumacher, and intrudes into the interior floor.
