Resumen:
The Atlantic Forest is an ecoregions complex that extends from the northeast of Brazil, by the coastal mountain ranges to Rio Grande do Sul. In the south, it enters to the east of Paraguay and northeast of Argentina, forming the Interior Atlantic Forest or the Paranaense forest. Although it occupies less than 1% of the planet´s surface, it contains 7% of the known species on earth. ?Juntos por la Selva? is an initiative of a small group of people in order to protect a fragment of the Paranaense forest. This is how, in 2011, the Itaovy, La Coral, and Yacutoro Private Reserves were created. They are located in Argentina, in the center of Misiones Province, in the Guaraní Department, just 15 km from San Pedro city. They conserve about 500 Ha of forest with an important number of plants and animals species. In order to document the macrofungi within these protected areas, 2 samplings were performed during the 2016 - 2017 period. A total of 190 samples were collected in different environments of the reserves. The material was dried, kept in freezer for a week, and deposited as reference in the CTES herbarium. The morphological analysis was made based on observations of macroscopic and microscopical characters with stereoscopic and optical microscopes. The species found were identified consulting specific literature. The Basidiomycota was the most diverse group and from which a larger number of specimens was obtained, representing 93% of the collections, belonging most of them to the Agaricales, Polyporales, and Hymenochaetales. The remaining species belong to Ascomycota and Myxomycota, representing 7% of the fungi of the reserve. The presence of common and widely distributed genera, such as Schyzophyllum, Fuscoporia, Pycnoporus, Trametes, Hexagonia, Marasmius, Mycena, was observed, as well as rare species that have been registered only few times (e.g. Ascopolyporus polychrous, Marasmiellus volvatus) and others that has been cited only in the original description (e.g. Mycena moconensis). A list of species is presented, with comments about its habitat and distribution, together with a catalog of photographs to illustrate the species. It is expected to move forward with the determination of the collected species and to continue with the samplings at favorable seasons for the development of basidiomata in order to achieve a more finished inventory. It is highlighted that although the reserves harbor a restricted fragment of forest, they protect a high diversity of fungi, being an important region for its conservation.
