Biodiversity of Macrofungi in Mapinguari National Park, Amazonas, Brazil

Objective: This study aimed to survey the fungal species found in PARNA Mapinguari-AM. Theoretical framework: Fungi are well known for their function as decomposers of organic matter, and have great ecological importance for maintaining the cycle of life. In the Amazon region, there is a vast diversity of macrofungi present, which can have very useful and important applications. These are important for human life, as they stand out in several areas, mainly ecological and economic. Method: The field research was carried out in the period from July to October 2022 and from September to November 2023. On the three trails existing in the park, it was decided to work only on trail 01 due to access and logistics of the research. The walking method was used along the 5 km of each trail, in order to demarcate the areas of possible macrofungi in substrates. Results and Discussion: Twenty-nine species of macrofungi were found and identified, divided into five families with the highest occurrence in the order Polyporales. Positive results were obtained, since the Mapinguari National Park has a large quantity of decomposing substrates, in addition to parts with high humidity, thus making it possible to find an excessive quantity of macrofungi specimens. Implications of the research: The results of this unprecedented study carried out in the area reveal the potential of the rich fungal biodiversity. Originality/value: Studies of macrofungi surveys contribute to the expansion of knowledge of mycological diversity. Therefore, the implementation of environmental education through interpretive trails as a perspective for this conservation unit in order to preserve and conserve the species of macrofungi existing in the park, as well as recording the existing macrofungi from trails 2 and 3 of the Mapinguari National Park are of fundamental importance for scientific knowledge.
