Glass contaminated mushrooms - any ideas?

Hey foragers. I had a great weekend foraging in norcal. Getting back to my car on my first day, I realized I locked my keys in my car. Being in the middle of nowhere, I ended up having to break in, it sucked! The first couple pounds I foraged were inside the car. At first I thought there was just a couple pieces of glass, and the way car glass breaks I could easily pull out the big chunks. But as I looked closer I realized there were some finer shards, and no matter what I do there will always be a piece left.

So I now have a couple pounds of yellowfoot, hedgehogs, and black trumpets with some glass in them. I’m reluctantly coming to the conclusion that I need to spoil these. But before tossing them I thought I would ask the community here if there are any ways to save these? One suggestion someone had for me was making a broth and using cheese cloth to filter. Would that work? Any other ideas? What would you do?
