Join us in transcribing Lichen collections! The lichen collection of the U.S. National Herbarium, Smithsonian Institution, with approximately 250,000 specimens, is the largest lichen collection in North America. Note to transcribers: USNH numbers are never placed on lichen sheets, and therefore that TC field can remain blank.
Please contact Sylvia Orli, Department of Botany, or tweet us at @sylviaorli @TranscribeSI for any questions or comments about the transcriptions.
