This is a fungus, not really a mushroom. It does not need to be boiled to remove toxins. It's widely used in multiple cuisines.
Grocery store mushrooms don't need to be boiled. If you're dealing with mushrooms and don't know whether they should be boiled, play it safe and don't eat them or serve them.
Fungi contain a large amount of nucleic acid (8–25%), most of which is ribonucleic acid (RNA). In order to reduce the damage on human health, fungal proteins must be processed in a certain way to reduce the content of RNA (to less than 2%), and decrease the risk of gout. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10742821/
