There is a considerable difference of opinion around the safety and potential medical use of psilocybin. In 2020, Psilocybin is Schedule I, the same category as Heroin and the most restrictive category of the Controlled Substances Act
This article discusses aspects of the debate.

A credible source will need to post a link to a DEA source similar to this one which mentions psilocybin in some category other than Schedule I. This question will resolve ambiguously if the Controlled Substances Act is repealed and another law defines a similarly regulated category, or if the DEA ceases to classify drugs.
