Answered by: Maulana Muhammad Asadullah Anwar Adam
Is eating mushrooms allowed?
In the name of Allah, the Most Gracious, the Most Merciful
There are 3 types of mushrooms, Edible mushrooms, Toxic mushrooms, and Psychoactive mushrooms.
Edible mushrooms are Halal because nothing renders them haram.
Toxic mushrooms are haram because self-harm is not allowed in Islam because Allah has stated ” and do not throw [yourselves] with your [own] hands into destruction ” 
Psychoactive mushrooms are haram because everything that causes intoxication is considered haram in Islam. 
Only Allah knows best
