BER can occur on zucchini. Same problem. Calcium not reaching rapidly
developing tissue at the end of the fruit. Calcium is a cell-wall
constituent. Without it the cell walls don't develop properly and the tissue
breaks down.

But there is also a disease called choanephera rot that infect the blossom
end of summer squash (including zucchini). Rather than a dry, flat spot with
a black fungus, this disease will turn the end of the fruit very mushy with
a heavy, fluffy growth of a gray fungus. Putting a mulch, especially an
organic mulch like wheat straw, underneath the plant will reduce incidence
of this disease.
