Weber, WA 1968: A taxonomic revision of Acarospora, subgenus Xanthothallia. - Lichenologist4: 16-31. [RLL List # 68 / Rec.# 20020] Keywords: ACAROSPORA/ XANTHOTHALLIA/ ENVIRONMENTAL MODIFICATION/ TAXONOMY/ SAXICOLOUS
Abstract: ["Ultimately I came to the conclusion that all of the taxa in Acarospora, subgenus Xanthothallia, could be accommodated in the old species, A. schleicheri and A. chlorophana, under the principle of environmental modification." 83 taxa, most of which were described by Magnusson, are reduced to synonymy.]
