Mould on wood

[Bud1234]

Currently I am getting my garage converted. The builder has brought some wood beams (strips or whatever it is called-sorry) to prepare the wall for plastering.

The issue is these wood has a lot of mould on it.
Will this spread or will it be a problem for us in the long run?

Please respond.
Thanks

Bud, what's the colour of this 'mould'? Pressure-treated timber (the stuff your builder should be using if it's going to be fixed to masonry) often has greenish surface deposits (residue of the preservative) which might look like mould to the untrained eye. Mould tend to be blackish or greyish in colour.
