Lendemer, J. C. 2011: A taxonomic revision of the North American species of Lepraria s.l. that produce divaricatic acid, with notes on the type species of the genus L. incana. - Mycologia 103(6): 1216-1229. [RLL List # 225 / Rec.# 33417]
Abstract: The divaricatic acid-producing populations of Lepraria in North America north of Mexico are revised with traditional morphological characters, chemistry, ecology, biogeography, and ITS1, 5.8S, and ITS2 sequence data. Three taxa are accepted: L. cryophila, L. hodkinsoniana sp. nov. and L. pacifica sp. nov. Both Lepraria crassissima and L. incana are excluded from the study area. Noncryptic, semicryptic and fully cryptic species concepts in Lepraria are discussed with emphasis on the practical integration of molecular characters into taxonomic frameworks based on non-molecular characters.
New taxa: Lepraria hodkinsoniana/L. pacifica
Notes: New species: Lepraria hodkinsoniana Lendemer and L. pacifica Lendemer
