Sometimes the mushrooms or mycelium bruise bluish/greenish, mostly due to handling or low humidity.

If you are not sure whether it is bruising or contamination(blue/green mold) take a clean cotton swab or a piece of tissue and very gently rub the spot in question. If someting comes off, a blue/green residue(=mold spores), then it is mold and your cake or mushrooms are contaminated.
