The Macrolichens of Ohio: A Revised Checklist1

DON FLENNIKEN AND RAY E. SHOWMAN, 2273 Blachleyville Rd., Wooster, OH 44691 and 2235 Blue Rock Lane, Grove City, OH 43123

ABSTRACT. The current revised list of macrolichens in Ohio contains 208 species, including twenty-eight species new to Ohio during the past 20 years. Nomenclature for Ohio's known species has been revised to reflect the most recent changes. Relative abundance is given for the species listed.

The checklist that follows is compiled from the above- TABLE 1 cited literature and is intended to bring current the macrolichen flora of Ohio. The nomenclature follows that Checklist of Ohio macrolichens. Relative abundance abbreviations: of Egan (1987, 1989). Where generic names differ from A= Abundant, >43 counties; C= Common, 17 to 43 counties; U= Uncommon, 8 to 16 counties; /?= Rare, 3 to 7 counties; E= Endan- those used by Taylor (1967, 1968), Taylor's genera are gered/Threatened, <3 counties; Q- Status unknown, all reports pre- enclosed in parentheses after the currently accepted date 1950. Names preceded by ( ) are new Ohio records since 1968. . Species preceded by an asterisk (*) are new additions to Ohio's lichen flora since Taylor.
