The University of North Carolina Chapel Hill Herbarium
has catalogued a single fungal specimen – Ustilago zeae (Beckm.)
Ung. – collected by Calvin Josiah Cowles.
However, as he is a very interesting gentleman, he gets a collector
Cowles seems to have made a single collection,
but as it was included in the Mycological Exchange of 1921, several herbaria (CUP,
NY, BPI, and ARIZ) have portions of that single specimen.
