Typification of names of lichen taxa described by W. Nylander from Angola and São Tomé e Príncipe

Abstract

William Nylander described two new lichen taxa from Angola and 24 from São Tomé and Principe based on material gathered by various Portuguese collectors, mainly Francisco Newton and Adolpho Moller. This material is deposited in the herbaria of Porto (PO). Coimbra (COI) and Helsinki (H-NYL). A list of these specimens and information on the types, including 12 new lectotypifications, is presented here.
