NEW: In collaboration with the IUCN, the IUCN Global Red-List is now featured on CNALH.
For all species included in the global red-list, the taxon profiles now also include red-listing information, e.g., checkout the profile of Mobergia calculiformis.

The Consortium of North American Lichen Herbaria (CNALH) serves as a gateway to biodiversity data of lichenized fungi throughout North America. It provides access to an array of different resources: specimen records, field observations, dynamic and static checklists, images, interactive keys, and a taxonomic thesaurus.
As a regular visitor, we invite you to join. Create your own account today! If you need access to specific resources, want to contribute occurrence records or images, report errors or simply provide feedback please do not hesitate to contact us at CNALH.help@gmail.com
News and Events
  • August 2021 - As part of the 9th Symposium of the International Association for Lichenology (IAL9) we held a Spanish workshop on how to manage data in the Consortium of Latin American Lichen Herbaria (CHLAL). The workshop was very well attended. You can download videos of Day 1 and Day 2 (please note: the videos are in Spanish and are large, ca. 2GB each; they will take a long time to download).
  • April 2021 - The GLOBAL Bryophytes and Lichens Network, funded by the recent NSF Grant, launched a new project website, which includes a description of the project, digitization resources, and education and outreach material.
  • January 2021 - Welcome our new portal manager Katie Pearson.
  • September 2020 - ASU and collaborators were recently awarded a new NSF Grant to Build a Global Consortium of Bryophytes and Lichens.
  • July 2019 - We now launched CNALH Help & Resources, a site with tutorials how to join and participate, and some useful programs that can be downloaded.
  • August 2018 - ASU receives a multimillion dollar grant from NSF to create the new NEON biorepository; these funds will substantially strengthen the Symbiota software platform and add new functionality from which CNALH will benefit significantly as well.
