I do not believe there is. Are you talking about identifying wild specimens? A regent test is not the way to do that as far as I know, not according to the knowledge of mycologists and fungi enthusiasts who know their specimens.
I don't think a plant identification app can work for mushrooms but I have to say don't try it unless you are with an experienced mycologist and even then only go by their knowledge of identification.
I think we should legalize them regardless worldwide and labs could test then sell wild ones legally all over. An evolving society of open hearts and advancing minds.
