Infection in Amanitas?

I ordered some amanitas from Bouncing Bear Botanicals; sat down to eat them and noticed that most of the shrooms have large brown/black spots. Are these infected, or is this most likely unwashed dirt or grow medium?

 

Are they Amanita Muscaria var. Muscaria, Amanita Muscaria var. Formosa, or Amanita Pantheria?

 

Muscaria var., grade B Europeans...

 

Oh, okay. Yeah, I've had a lot with brown and black spots and I've never had any problems. Now if it was Amanita var. Formosa, then that would be a different story.

 

Just read that they're best dried in ovens, so maybe they got burned a little...
