I am trying a new way to preserve fungus that I thought of: cover them in rubber cement. I'm using mushrooms that are slightly dried. This way it keeps a certain amount of flexibility, then I cover them in rubber cement. My dad told me that the mushrooms might rot from the inside. Is he right? Is this a good idea? I have one that's been covered in rubber cement for 2-3 days now, and it seems to be doing fine.
