I don't believe there's a loophole, if you're talking about the US. There are indeed mushroom products in smoke shops, but they're amanitas. The effects are much more mild.
Psylocybin and psylocin are Schedule I wherever they occur.
The only practical loophole is spores, which can be sold for research purposes, though not in all states, and are illegal to germinate anywhere. Still, many online outfits sell and ship liquid culture (mycelium suspended in liquid), which is illegal but it appears nobody cares too much.
