Magic Mushrooms of the Pacific Northwest and Mushrooms and Mankind, collaborated with other well-known mycologists such as Dr. Gastón Guzmán, which led to the discovery of new species of fungi of the genus Psilocybe.

One of Allen's important discoveries is the Chitwan strain of the fungus Psilocybe cubensis, which he collected while traveling in Nepal in the 1990s. The fungus was found in the Chitwan region, growing on animal feces, and has since gained popularity among growers for its high potency and resistance.
