Purdue University Herbaria

The Purdue University Herbaria, comprised of the Arthur Fungarium and the Kriebel Herbarium, are located in the Lilly Hall of Life Sciences at Purdue University. Together, the Herbaria contain over 200,000 specimens, with some dating as far back as 1769​.

The Arthur Fungarium (PUR) exclusively contains the collection of the Pucciniales, or rust fungi (formerly Uredinales).

The Kriebel Herbarium (PUL) contains non-rust fungi, vascular plants, lichens, algae, and bryophytes.
