Hafellner, J/ Obermayer, W 2005: Beobachtungen an einer sorediösen Population von Pseudevernia furfuracea. - Herzogia17: 45-50. [RLL Suppl.] Keywords: CHEMICAL STRAIN/ VEGETATIVE DIASPORES/ SPECIES PAIR CONCEPT
Abstract: Morphology and secondary chemistry of a population of Pseudevernia furfuracea being isidiate and sorediate at the same time is studied in some detail. Based on observations presented below and data of earlier records it is concluded, that it is not convenient to apply a taxon name to sorediate Pseudevernia specimens
