Their was a really long post about whether or not it's same to eat mushrooms from a conaminated cake. People seem to be really worried about this, but the general concensus was that if they looked normal, it's ok. People who have been around ahrooms a long time (Shroom Wizard, Mushroom John, etc) said they dont' worry about it. They grow in the wild around a lot of shit(pardon the pun . I've never had the opportunity to eat any from a contaminated cake, but I don't think I'd really worry about it.

BucketHead. How long have the jars been incubating for? Mycelium like any other organism produces waste products. Mycelial waste is a yellowish color, this COULD be what you are seeing. Then again it COULD be contamination as well.

One of the big questions is whether or not the mycelial network (if contaminated) will carry toxins from contamination through the network to your fruit bodies. If the network DOES transport these toxins then it would not be safe to eat them if the network does not transport the toxins the mushrooms would be safe to eat. Unfortunately I haven't seen any scientific evidence either way. As the saying goes, better to be safe than sorry. You can always make more shrooms, but you only get one life. Be sensible.

Jerry95: The signs are rotting, mushy, smelly discolored mushrooms. Take a look at the pics in the gallery, that is how your shrooms should generally look, if they smell or look "funny" I wouldn't eat them, if you do, it's essentially like eatting rotten food. You wouldn't eat a rotten apple or banana would you? So don't eat rotten mushrooms.
