SUMMARY:

Astrocaryum vulgare Mart. is a perennial palm tree known as tucumã-do-Pará, prevalent in the Eastern Amazon, especially in the state of Pará. In recent years, this palm tree has increased its commercial value associated with its use in the food industry. Currently, 2,500 species of fungi associated with palm trees are known, including endophytes, phytopathogens and saprobes, with fungi of phylum Ascomycota being the main group found on decaying substrates of palm trees, but for the Amazon biome these data are probably undersampled. Reports of asexual ascomycetes associated with tucumã are limited to specimens of potentially phytopathogenic genera. Due to the scarcity of data related to A. vulgare, this plant was selected as an interesting object of study, to investigate the diversity of asexual ascomycetes associated with this Arecaceae. Thus, the objective of this work is to carry out a taxonomic study of asexual ascomycetes associated with decaying substrates of A. vulgare in three areas in the Eastern Amazon, Pará, Brazil. In order to achieve this goal, three collections of decaying substrates of A. vulgare will be carried out in three areas of the state of Pará (Abaetetuba, Cachoeira do Arari, and Soure), between December 2023 and June 2024. The collected substrates (sheaths, bunches, leaflets, petioles, and rachises) will be processed according to the washing technique under running water and kept in a humid chamber for up to 45 days, with daily observations under a stereomicroscope. Semipermanent slides will be prepared to visualize the reproductive structures of asexual ascomycetes under an optical microscope and identify them with specialized literature. For fungi that represent new species and new records for the Amazon, Brazil, South America and the Neotropics, taxonomic descriptions, geographic distribution, comments, and illustrations will be provided. With this study we hope to expand the data on Amazon Funga, offering a contribution with the asexual ascomycetes identified and associated with A. vulgare.
