bruising and blueing

is it possible for the cake to bruise? i see what appears to be blueish tint on the top of my cake. the cake has been fruiting for some time and has a nice amount of mushies growing out of it. the "bruised" area is in remotely the same place as where i picked it up to move it. no funky smells or anything. all info is much appreciated. also i only touch the cakes after i have washed my hands and rinse them with 91% alcohol.

That is perfectly normal. No worries! 
The cake was probably slightly stressed where you picked it up.

You could post some pictures?
An easy mold test: Use a small piece of clean tissue and make it a bit wet, then very gently rub it at the coloured part. If any colour comes off the cake to the tissue then it's mold (mold spores). If nothing comes off then it's just bluing.

DO NOT believe that tissue or qtip method man. It ALL comes off. Bruising smears off easily.
It's blue because it's probably dehydrated. Pick it up and compare it with a non bluing cake. It will be lighter.
One of two methods you can do is put it in a small saucer filled with water for 12-24 hours and/or, to be safe and stay safe, put an inch or two of vermiculite on the top of the cake and moisten it to the point right before drenching (a puddle of water). It will slowly take water from it and you can keep feeding it water that way so your fruits have all the water they need.
Usually it's from handling the cake too much but IME it happened more from drying (I didn't handle them too much until harvest though)
GOOD LUCK and the qtip method and the tissue or anything with smearing it off is misinformation. <--RR says this many, many times so do other TC's

Hmm.. that's a new one to me, but I'm new to the Shroomery too of course. I've heard this advice 1000 times (which doesn't make it right, I know) and used this method myself several times when I grew cakes, but of course, just because the bluing didn't smear off when I used it doesn't mean it could not do it. If people have actually been able to get their tissues blue from gently rubbing on spots of oxidized psilocin then of course the method isn't sound. And I apologize for bad info and thank you for educating me.
However I would like to read more, now that you say this is something that experts have argued against. Got any links to said discussion?

This may be an overkill but:

That is flat-out wrong and the q-tip test was proved bogus years ago. The pigments from bruising will easily rub off on a q-tip.
To the original poster, just watch and see what happens. It doesn't appear to be mold. If it's an abort, you can wait until you pick the rest of the flush to remove them. Don't disturb the cake now. RR

RogerRabbit said: You can also set the cake in a saucer of water overnight to hydrate during mid-flush.
There is no q-tip test. It's total bunk. Bruised mycelium will easily rub off on a q-tip and this has resulted in thousands of perfectly fine, but dry cakes being tossed out over the years due to that misinformation. RR

Thanks. I am very surprised to hear this. I've only used tissue, never q-tips, personally, I don't know if that's what has made the difference, or this is just coincidental. I have of course seen lots of mushrooms give off blue colour to paper, but I had never imagined a cake would be able to unless one literally plucked off some of the mycelium. Anyway, I won't mention the method again, of course.
