Checklist of lichens that grow on Mount Desert Island

Checklist of lichens that grow (or are reported to grow) on Mount Desert Island

(updated 13 April 2010)

Below is a working checklist of Mount Desert Island's lichens. Because this checklist has been compiled from sources that included lichens from several islands near Mount Desert Island as well as from MDI itself, it is necessary for the Champlain Project to verify the presence of each of the species on Mount Desert Island. Classification follows Tehler and Wedin's "Systematics of lichenized fungi", chapter 17 in the second edition of Lichen Biology (Nash, 2008), with adjustments for synonymy from Hinds and Hinds (2007). Common names are from Hinds and Hinds (2007) and Brodo et al. (2001). For full citations, please see the references listed at the bottom of this page.

The Champlain Project thanks Irwin M. Brodo, Douglas N. Greene, James W. Hinds, Thomas H. Nash III, and Anders Tehler for their help and advice in the presentation of this checklist.

Please send corrections and updates to info@vfthomas.com. Photographs are welcome. Thank you.

Notes:
   1. Esslinger (2009) recognized Cladonia cervicornis ssp. verticillata as one of two North American subspecies of C. cervicornis. Hinds and Hinds (2007) recognized it at the species level.
   2. Cladonia diversa was listed in Esslinger (2009) but was not found in either Brodo et al. (2001) or Hinds and Hinds (2007).
   3. It needs to be determined whether Sullivan's specimen is ssp. mitis (which Esslinger (2009) recognized at the species level as C. mitis), or the typical C. arbuscula.
