Annotated Checklist of Maine Macrolichens

Jim Hinds - March 17, 2017

This checklist lists the 411 species of macrolichens found in Maine as of 2016. The checklist includes notes on distribution, conservation status and substrate as well as reference information. It also gives the currently accepted name for nearly 250 additional synonyms. Names follow the latest North American Checklist (Esslinger 2016) except as noted.

Species Only Checklist

A total of 21 species are in the checklist which are new to New England since Hinds & Hinds 2007: Bryoria americana, Cetraria ericetorum, Cetraria islandica ssp. islandica, Cladonia acuminans, Ephebe perspinulosa, Cystocoleus ebeneus, Pannaria tavaresii, Parmelia fraudans, Parmelia pinnatifida, Parmeliella appalachensis, Physcia alnophila, Physcia pumilior, Physconia grumosa, Pilophorus cereolus, Rusavskia papillifera, Umbilicaria polyrhiza, Usnea chaetophora, Usnea lapponica, Usnea macaronesica, Usnea praetervisa, and Usnea subrubicunda.

There are also 7 species new to Maine, but not New England: Cladonia dahliana, Cladonia floridana, Hyperphyscia syncolla, Melanelia culbersonii, Psorula rufonigra, Punctelia appalachensis, Usnea scabrata.

Differences from 2016 NA checklist:
1. Bryoria americana is considered separate species from B. trichodes (not in checklist or in Hinds & Hinds 2007).
2. Cladonia sobolescens and C. polycarpoides are considered separate species, distinct from C. subcariosa.
3. Usnea evansii and U. tristis are considered conspecific with U. strigosa (separate in checklist, conspecific in Hinds & Hinds 2007).
4. Usnea substerilis is retained as a separate species, but is considered conspecific with U. lapponica in 2016 NA Checklist.

References: (1) the first reference to report the species in Maine and (2) a readily available reference that includes a description of the species, often Hinds and Hinds 2007 which is a flora of New England macrolichens.
