Michigan State University Herbarium Lichens
The lichen collection of the Michigan State University Herbarium (MSC) totals over 150,000 accessioned specimens from many regions of the world. The herbarium maintains over 10,000 exsiccati specimens, many of which are not otherwise available in North America. This extensive collection was assembled largely through the efforts of Dr. Henry A. Imshaug, the curator of the Cryptogamic Herbarium from 1958-1990.
