Noticed blueish slightly blackish patch on my cake - possibly contamination?

Hi guys! Just noticed a wee blueish, slightly blackish patch on my cake. There is also a couple patches of pins running down the same side that look almost "frosted" just down from them. Poss contam? 🤔 Answer: From the pictures you shared the blueish part looks like mycelium bruising.
