Massal. from Bolivia, of which three, O. austroamericana (Räsänen) Räsänen, O. subpallescens f. Verseghy uruguayensis Verseghy and O. upsaliensis (L.) A. Massal., are new for the country. Ochrolechia subpallescens f. uruguayensis is shown to differ chemically from O. subpallescens s.str., but its taxonomic rank needs to be clarified with molecular studies. Ochrolechia africana Vain. is also reported for the first time for Tanzania and Uruguay, and O. austroamericana for Ecuador.enTaxonTanzaniaGenusGeographyRank (graph theory)LichenBotanyBiologyarticle
