Área de conservación líquenes Pyxine taxonomía Background and aims: Pyxine (Lecanorales, Physciaceae) is an interesting genus, which is little known in the Argentinian territory, for this reason a study of the species presents in the Yaboty Biosphere Reserve (Misiones, Argentina) is proposed. M&M: The identification of the species was carried out following the methodology conventionally used for the study of lichens, which includes a morphological and chemical analysis. The macroscopic characters were studied with a stereoscopic microscope. In order to determine the type of plectenchyma and study the morphology of ascospores, freehand sections were made, which were subsequently mounted in 5% potassium hydroxide and observed under an optical microscope. The identification of the lichen substances present was carried out by means of specific color reactions with 10% potassium hydroxide, ultraviolet light chamber test and thin layer chromatography with solvent A. Results & Conclusions: In this contribution Pyxine daedalea, Pyxine katendei, Pyxine maculata y Pyxine sorediata are cited for the first time for Argentina. It is presented a dichotomous key, a brief description of the species in the area, geographical distribution, observations and illustrations of each of them. It is considered that this work is a great contribution for further taxonomic and ecological investigations. Introducción y objetivos: Pyxine (Lecanorales, Physciaceae), es un género interesante, poco conocido en el territorio argentino, por ello se presenta un estudio de las especies, presentes en la Reserva de la Biosfera Yaboty (Misiones, Argentina).M&M: La identificación de las especies fue realizada siguiendo la metodología convencionalmente utilizada para el estudio de los líquenes, que incluye un análisis morfológico y químico. Los caracteres macroscópicos fueron estudiados con un microscopio estereoscópico. Para determinar el tipo de plecténquima y estudiar la morfología de las ascosporas se realizaron cortes a mano alzada, que fueron posteriormente montados en hidróxido de potasio al 5% para ser observados en microscopio óptico. La identificación de las sustancias liquénicas presentes fue realizada mediante reacciones puntuales de color con hidróxido de potasio al 10%, test en cámara de luz ultravioleta y cromatografía de capa delgada con solvente A. Resultados & conclusiones: En esta contribución se citan por primera vez para la Argentina: Pyxine daedalea, Pyxine katendei, Pyxine maculata y Pyxine sorediata. Se presenta una clave dicotómica y una breve descripción para las especies en el área, distribución geográfica, observaciones e ilustración de cada una de ellas. Se considera que este trabajo es un gran aporte para posteriores trabajos taxonómicos y ecológicos.
