Bread mold

is a kind of fungus that usually forms on the surface of bread. This fungus causes the bread to lose its nutrients from the spot where it is present

. It is formed due to the presence of moisture on the surface of the bread and once it sprouts it keeps on growing and spreads from the original spot to the whole surface of the bread.

There are many different kinds of fungi in the environment and the bread can catch one of them when exposed to the air. As the bread has some moisture and is also nutrient, the mold would start growing and spreading on the surface of the bread
