Ganoderma lucidium (Reishi) contamination?

Apologies for the blurry picture. I am looking for some advice on a block of reishi that I put into my FC yesterday. The yellow coloration has come on in the last 24 hours and is quite noticeable. I have several other blocks in there that I don't want to contaminate so I would like to err on the side of caution.
Is this a characteristic color of reishi mycellium or an easily identifiable contam? I mostly deal with blue/green molds and wetspot around here.
Very appreciative of any information.

Cut back on your moisture

I can lower the moisture tonight and see what happens. I have the block placed on the lowest shelf by the exhaust, because it makes me feel better.
I looked again and it seems as though there is another 'yellowish' patch slightly away. I have not had much experience with yellow contams (only ever seen on some agar plates that got exposed to open air).
If its pins that's fine with me. Thanks for the input.

If youre worried make a separate fc. Try setting your block on a plate and coving it with a plastic bag for humidity or something else simple. Im sure you could find a good tek on here. I think you'll be just fine though.

In my experience, Reishi looks pretty funky as it grows fruit bodys. Its a pretty aggressive fungus and if its growing well it doesn't readily contaminate.

Don't do that.

Your block looks great and that is a pin. I repeat, DON'T cut back the moisture, it's perfect the way it was.

Thanks for the replies everyone. I didn't end up cutting back humidity. Glad to hear the consensus is that it's a pin! I have another block set to go in any day now.
Is there a thread on this forum that would be better to ask simple questions in? I have GGMM by Stamets but there are a lot of species specific questions that I seem to be having a hard time getting answers. Guess I could start a grow log...
Thanks again!
