LENDEMER1 AND RICHARD C. HARRIS2 ABSTRACT. – Arthothelium lichenale is placed in synonymy with Mycoporum compositum. The morphological distinctions between Collema pustulatum and Leptogium apalachense are discussed and the North American distributions of the species are revised. The distribution of Lecidea roseotincta in North America is extended to include the central and southern Appalachian Mountains. The distribution of Lecidella subviridis is expanded in northeastern North America. Pyrenula reebiae is placed in synonymy with P. leucostoma and both species are illustrated and discussed. Pyrenula shirabeicola is removed from synonymy with P. pseudobufonia and both species are illustrated and discussed. The following taxa are newly reported from North America: Calvitimela cuprea (Canada, Newfoundland & Labrador), Hypotrachyna consimilis (U.S.A., North Carolina), Schismatomma graphidioides (U.S.A., Alabama and New Jersey). KEYWORDS. – Biogeography, Collemataceae, North American Checklist, Lecanoraceae, Lecideaceae, Parmeliaceae, Pyrenulaceae, sterile crust. INTRODUCTION As a result of fieldwork carried out throughout eastern North America, particularly in the southern Appalachian Mountains, we have studied new collections that prompted us to reexamine our understanding of recognized species, their distributions, and ecologies. Routine curation of the herbarium at the New York Botanical Garden led to similar studies, as has the identification of specimens that were newly donated to the herbarium. While such studies typically result in discrete taxonomic or floristic publications, there are often also brief notes that merit publication but are not easily accommodated in a standalone contribution.
