Grazed oncidium root tip

[Mercurianmad]

Aw man! I noticed my oncidium was starting to get a little mold on the lower pseudobulb, on the dried paper bits attached to the bulb. So I lifted it out of the lava rock medium to raise it up so none of the pseudobubs were buried, and one of the new roots grazed the lava rock and the root tip broke off. Will it still grow? This plant needs all the roots it can get.
