<p><i>Phlebopus bruchii</i> is a culturally important and culinary valued fungus endemic to the Montane Chaco forests of Córdoba and San Luis, Argentina. Recently, the species has been categorized as Critically Endangered following the International Union for Conservation of Nature criteria, primarily due to habitat loss. This work aims to identify and predict its remaining suitable habitat based on citizen science collaborations, a fundamental step in developing effective conservation strategies for the species. Species Distribution Models and the collection of presence data throughout different social media platforms were carried out. The resulting habitat suitability map was analyzed considering vegetation units, current land cover, and areas affected by fires in 2024. A total of 84 occurrence records of <i>Phlebopus bruchii</i> were compiled from Córdoba and San Luis provinces. After removing duplicates that fell within the same raster cell, 70 unique records were retained for modeling. We first developed an initial habitat suitability model (Map 1) using 35 records. This model was then validated and updated with 35 additional records obtained in the subsequent 2024 season. The final model (Map 2) presented a high performance, with results indicating moderate to high habitat suitability in remnant patches of Montane Chaco forest in Córdoba and San Luis provinces. Approximately half of the predicted suitable habitat is located in areas still facing intense anthropogenic pressures, including intentional fires, agricultural expansion, livestock grazing, and urban development. These findings highlight the urgent need for targeted conservation actions in native forest remnants and demonstrate the critical role of citizen science in documenting rare fungal species. Additionally, the conservation status of <i>P. bruchii</i> is reassessed, and its categorization is suggested to be kept based on new generated data.</p>
