Shirley C. Tucker Herbarium (LSU) at Louisiana State University

Bernard Lowy Mycological Herbarium (LSUM)

Mission Statement

We study the biodiversity of vascular plants, lichens, and fungi from the state of Louisiana and around the world. A permanent reference collection is held within these herbaria that documents historical distributions and biodiversity, providing botanical information to researchers and the public. Our research interests include the study of native and introduced plants and fungi, their ecology and evolution.

Hundreds of specimens are accessioned into the herbarium each year, and most readily digitized. With the help of National Science Foundation grants and students, we’ve databased and imaged our North American holdings in the Shirley C. Tucker Herbarium (LSU) and all of the Bernard Lowy Mycological Herbarium (LSUM). The LSU and LSUM specimen databases can be accessed through the all specimens portal. In order to broaden your search of a particular taxonomic group, select links to respective herbaria consortia portals.

History of LSU Herbaria

On October 15th, 2015, the herbarium was named in honor of Dr. Shirley C. Tucker for her contributions to science and her generous endowment to support the herbarium and its related research in plant systematics. Dr. Tucker is an LSU Boyd Professor emerita whose research spans the fields of floral development, plant systematics, and lichen systematics. Returning to LSU for several days, Dr. Tucker celebrated the ribbon cutting of the Shirley C. Tucker Herbarium by attending a Special Symposium and a winning LSU football game. Notable guest speakers included lichenologist, Irwin Brodo of the Canadian Museum of Nature, Ottawa, and plant scientist, Chelsea Specht of UC Berkeley.

Founded in 1869, the Shirley C. Tucker Herbarium at Louisiana State University is the oldest collection of preserved plant specimens in the Gulf South and is the second largest collection of Louisiana plants. Originally composed entirely of specimens of vascular plants, LSU's herbaria now also include fine collections of lichens and fungi, as well as bryophytes and algae. In all, the LSU Herbaria contain ca. 180,000 specimens, with over 40,000 lichens (the largest lichen collection in the Gulf Region) and ca. 25,000 fungi (the second-largest collection of its kind in this region).
