Black mold in IMO1

so I just recently made 2 collections 1 from a local untouched spring fed riparian habitat in the mountains and on from my property under leaf litter from giant shrubs surrounding the property, the one from mountains was pretty much perfect and contained little or no colors other than the white Cotten candy on top and throughout, but the one I collected from my property, it had some nice mycelium growing in too like the other but it also had a little blue a little red and than when I broke it up I saw that it had definite black mold growing on some of the inner parts, i tried my best to get the pieces of the rice patty with good mycelium and no black mold but definitly got a little in my IMO2, my question is.. is this IMO2 still good to mix with my other good IMO when making IMO3 or shoukd I avoid using this collection?
