A serious disorder of tomato, pepper, cucumber and eggplant, blossom end rot is an environmental problem not fungal most often caused by uneven watering or by calcium deficiency. These can be related; uneven watering can interfere with the uptake of calcium.

Tomato Rots On Bottom – Identifying Tomato Plants With Blossom Rot
The affected tissue breaks down rapidly and the area becomes sunken, dark brown or black, and leathery. This can happen at any time as the tomatoes mature, and most often on the first tomatoes of the season. Blossom-end rot is caused by insufficient calcium in the tissue of the tomato. This means that the rot can occur even when there is an ample supply of calcium in the soil, stems or leaves. Actively growing parts of the plant such as developing tomatoes must have a continuous supply of calcium to prevent these spots from developing.
Why are your tomatoes rotting on the bottom? Unfortunately, they probably have blossom-end rot. Calcium is needed for normal cell growth. Some blossom-end rot is more or less normal in the first tomatoes of the season, since the plants are usually under stress during the initial fruit set. If the damaged portion is small, you can trim it off and enjoy the rest of the tomato.
