Checklist of lichens that grow on Mount Desert Island

Maine Biota Project

Lichens of Mount Desert Island

(Phylum Ascomycota, Subphylum Euascomycotina)

Below is a working list of Mount Desert Island’s lichens. Because this list 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.

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.
