The liver and the kidneys are the organs that deal with the toxins, and the major cell damaging occurs there. For Psilocybe Cyanescens, I must give admit that I don't know what Psilocybe does for dammage except neurotoxic and psychotropic intoxication, so I will refere to poisenouse shrooms, and to Orellanin and Amatoxin as the liver & kidney damaging toxins. So I stand corrected =)
