Background and aims: A revision of the genus Emmanuelia in northern Argentina is
presented, in order to increase the knowledge of this group of lichens in the country.
The species belonging to this genus, recently described, were previously within
Lobaria.
M&M: Samples deposited in the CTES herbarium and collected in the forests of
northern Argentina were studied. Morphological and anatomical analyses were
carried out using a stereoscopic and optical microscope, and chemical analysis
of the material was performed with spot colour reactions with 10% potassium
hydroxide (K), sodium hypochlorite (C), and K followed by C (KC), and thin layer
chromatography (TLC).
Results: Through the morphoanatomical and chemical studies of the material
deposited in the CTES herbarium, the presence of three species in the north of
Argentina was determined. Emmanuelia elaeodes and E. erosa are recorded for
the first time for the country, and E. tenuis extends its distribution for Corrientes
province. Each species is described and photographed, and a dichotomous key to
the species present in Argentina is provided.
Conclusions: This work increases and updates the knowledge about this group
of lichens in Argentina, with the addition of species previously not known for the
country. Furthermore, it was possible to confirm the presence of E. tenuis and to
determine that E. cuprea y E. patinifera would not be in Argentina.
Key words: Diversity, Lobaria, Lobarioideae, Peltigeraceae, rainforests.
