Cullen Taylor Clark

Citizen naturalist & field mycologist

A citizen naturalist whose field collecting in the mountains of southern Africa helped bring Psilocybe maluti — and the Basotho tradition around it — into the scientific record, as a co-author on the 2024 description.

The southern African fieldwork

Cullen Taylor Clark represents a newer kind of figure in this archive: the citizen naturalist whose careful field observation feeds directly into formal science. Working in the Maloti–Drakensberg, Clark was among those who collected and documented the material behind the 2024 description of Psilocybe maluti, the native southern African psilocybin mushroom used by Basotho healers.1

A better model of credit

What makes the P. maluti work notable is not only the mushroom but the authorship. The 2024 paper credits its citizen collectors alongside academic mycologists and — unusually — names the Mosotho traditional healer Mamosebetsi Sethathi as a co-author rather than an anonymous “informant.”2 It is the collaborative, credit-sharing model this archive hopes to see more of: the people who hold the knowledge, and the people who do the legwork, named on the science rather than mined for it.
