According to the Collins English Dictionary which I just grabbed off my shelf (and I am British):

Mould (U.S. mold)

1. a shaped cavity used to give a definite form to fluid or plastic material (and about eight other similar definitions!)
2. a coating of discoloration caused by various saprophytic fungi that develop in a damp atmosphere on the suface of stored food, fabrics, wallpaper, etc. (and a couple of similar definitions)
3. loose soil esp. when rich in organic matter (and in poetic usage, the earth)

I agree with you that it is probably the third meaning, but I find it amusing to think it might be the second. XD
