green around edge of shroom cap

So heres what going on I picked some mushys and dryed them out in a napkin yesterday and now today they have a green looking color around the edge of the cap. Is this ok to eat or should I toss them? Also its the puerto rican strain from RS

probably more blue than green, especialy if it just dried out as oposed to steaming up in a plastic bag.
It should just be discoloured without any obvious mold sitting on the surface,

Id guess bruising not mold.

yea bruise or oxidation, very unlikely to get mold like that.
If you like them to stay nice and white, harvest by gently twisting till it disconnects, then oven dry at low temp with oven door open.

I use a dehydrator, just go inside and cut the cord to the heater element and let her blow 'em dry.
