Between a Rock and a Hard Place: Chrysothrix susquehannensis is More Widespread in Eastern North America than Previously Thought
Lendemer JC and Clark PW. 2021. Between a Rock and a Hard Place: Chrysothrix susquehannensis is More Widespread in Eastern North America than Previously Thought. Opuscula Philolichenum. 20:81-87
ABSTRACT: Chrysothrix susquehannensis was originally described from vertical rocks faces at a single locality in southeastern Pennsylvania, U.S.A. Here we document new occurrences discovered as result of fieldwork and the revision of herbarium specimens. We show that C. susquehannensis, although rare, is widespread in the Appalachian Mountains of eastern North America, with a disjunction in New Mexico in southwestern North America.
