PASSO, Alfredo; DIAZ DOMINGUEZ, Raúl Enrique  e  RODRIGUEZ, Juan Manuel. The genus Pannaria (Pannariaceae) in Argentina: new records and updated knowledge. Bol. Soc. Argent. Bot. [online]. 2020, vol.55, n.3, pp.1-10. ISSN 1851-2372.  http://dx.doi.org/https://doi.org/10.31055/1851.2372.v55.n3.25727.

Background and aims: As part of long-term studies focused on the diversity of lichenized fungi in Argentina, a review of the genus Pannaria in the country is presented. This genus have never been studied in detail in our territory. M&M: The morphology, anatomy and chemistry of the species were studied through the review of fresh specimens collected in the field and the study of different herbarium collections, following standardized protocols. Results: Fifteen species of Pannaria are registered for Argentina, 3 of them for the first time: P. conoplea, P. malmei, and P. tavaresii. A new synonym is proposed (P. euphylla = P. calophylla). Descriptions, photographs, and actualized information on their distribution and ecology, and a key for their identification are presented. Conclusions: Most of the mentioned species were found in the Andean-Patagonian forests, with the exception of P. conoplea, P. malmei and P. tavaresii, which were found in central Argentina, in high altitude forests of Polylepis.
