In this study, the diversity of Pluteus sect. Pluteus, and Volvopluteus in Turkey is poorly known due to insufficient morphological descriptions and a lack of DNA sequence data. Although the genera have been well-studied in Europe, North and South America, the diversity of Pluteus, mainly Pluteus sect. Pluteus and Volvopluteus are two closely related genera of Pluteaceae that comprise saprotrophic fungi. Fourteen new species were cited for Paraguay. The family with the most representative members was Polyporaceae, with 15 species. Four field campaigns were carried out during 2019-2020 in the Ybycui National Park, resulting in the identification of 31 families and 77 species of basidiomycetes and ascomycetes.

The need for scientific information in mycology encourages the study of protected areas in order to publicize the funga of the country. The peak in the study of macrofungi in Paraguay in recent years has marked a before and an after in the fungal history of the country. Palabras claves: diversidad fúngica, Funga, micobiota, Polyporaceae, Bosque Atlántico del Alto Paraná Funga of the Ybycui National Park: preliminary list of species of macrofungi and new citations for Paraguay. Se citan 14 especies por primera vez para el Paraguay. La familia con más representantes fue Polyporaceae con 15 especies. Se realizaron cuatro campañas de colectas en el Parque Nacional Ybycuí (comienzo de Bosque Atlántico del Alto Paraná y finales de Chaco Húmedo) durante el período 2019-2020, y como resultado se registraron 77 especies de macrohongos distribuidos en 31 familias. La necesidad de información científica de base en micología, incentiva el estudio y relevamiento de áreas protegidas con la finalidad de dar a conocer la funga del país. El auge del estudio de macrohongos en el Paraguay en los últi-mos años ha marcado un antes y un después en la historia micológica del país.
