Coleção científica de fungos macroscópicos: uma proposta para a conservação do acervo da Micoteca Didática do CESP/UEA

Abstract

This work aimed to "implement a scientific collection of macroscopic fungi from dehydrated fungi, seeking to conserve and expand the collection of the Teaching Mycotheca of CESP/UEA, collecting species in the municipalities of Parintins/AM and Barreirinha/AM." Collections were carried out weekly during two distinct periods from October to December 2025 and from January to March 2026, totaling six months of continuous visits to the sites previously defined for sampling. The methodology used was of a qualitative-quantitative type, with identification based on macro- and microscopic morphological characteristics, fungal treatment according to the characteristics of each species, dehydration, and preparation of envelopes with data related to each species. In total, 125 species were recorded, distributed across 2 phyla, 14 orders, 67 genera, and 41 families, with emphasis on Polyporaceae, Ganodermataceae, and Agaricaceae. These species were treated, stored in paper envelopes, and arranged in cardboard boxes according to families and orders, finally being incorporated into the CESP/UEA Mycotheca. Greater species richness was observed in secondary forest areas, riparian forests, shaded areas, and during the rainy season, evidencing the influence of the rainfall regime on the local mycobiota. As an additional product of the research, an e-book was developed containing guidelines on biological collections, conservation, and storage of macrofungi, with the aim of promoting interest in Mycology, Amazonian Mycodiversity, and scientific dissemination. The results reinforce the importance of urban forest fragments for the conservation of fungal diversity and for the advancement of knowledge about the ecological and biotechnological potential of Amazonian macrofungi.
