SUMMARY:

Conidial fungi are essential components of the decomposition process and nutrient cycling in aquatic environments, providing nutrients for different levels of the food chain. In freshwater environments, conidial fungi are frequent and classified into three ecological groups: aero-aquatic hyphomycetes, aquatic-facultative hyphomycetes, and Ingoldian hyphomycetes. In Brazil, most taxonomic studies with this group occur in aquatic environments of the Caatinga and Atlantic Forest biomes. For the Amazon, studies remain punctual, but already indicate a high diversity of conidial fungi in submerged litter. This scarcity of data about the diversity of these fungi in the Amazon makes it urgent to carry out new studies in the region. Thus, the aim of this study is to realize a taxonomic study of conidial fungi associated with submerged decaying plant litter in streams present in the Utinga Camillo Vianna State Park, Belém, Pará. Three collections of submerged decaying litter (leaves and twigs) will be carried out between February 2022 and August 2022. The collected substrates will be submitted to the washing technique under running water, incubated in humid chambers at room temperature for up to 45 days, and daily analyzed under a stereomicroscope. The fungal structures will be mounted on semi-permanent or permanent slides and the identification of specimens will be based on morphological studies with the aid of specialized literature. The slides and dried samples of the identified fungi will be incorporated into the Herbarium João Murça Pires (MG) of the Museu Paraense Emílio Goeldi. For new species and/or new records for Amazon, Brazil, South America, and the Neotropics, taxonomic descriptions, comments and illustrations will be provided. The results of this study will contribute to expand the knowledge of the diversity of conidial fungi in Amazonian aquatic environments, which remain underexplored despite the numerous habitats available for investigation.
