Ecology of polyporus fungi (Basidiomycota) of mangrove in the Southern Bahia Bianca Vicente Figueiredo, Jorge Luiz Fortuna

Abstract

Fungi are essential components for the functioning of ecosystems, they are found in different environments as well as mangroves. They are uni or multicellular heterotrophs that show great morphological variation. This study aimed to identify polyporous fungi (Basidiomycota) that occur in a mangrove in the municipality of Alcobaça-BA. Were carried out during 2019, held in January, April and December in three different areas identified as area A (preserved), area B (stressed) and area C (anthropized) of the mangrove. Ecological analyzes were carried out to calculate species richness (R); constancy (C%); Shannon-Wiener diversity index (H'); Sorensen similarity index (Ss); Margalef richness index (DMg); Menhinick richness index (DMn); Berger-Parker index (d) for dominance and for calculating diversity measures, the Whittakker β diversity measure was used. All material collected and identified was deposited in mycology collection of the Campus X of Bahia State University (UNEB). Were collected 271 individuals who were divided into three distinct orders: Polyporales, Hymenochetales and Gloeophyllales. Followed by the Polyporaceae families with nine representative species (Hexagonia hydnoides (SW.); Pycnoporus sanguineus (L.) Murril; Trichaptum sector (Ehrenb.); Tyromyces sp. 1; Tyromyces sp. 2; and with one species the families Hymenochetaceae (Fuscoporia sp.) and Gloeophyllacea (Gloeophyllum striatum (Sw.) Murrill). All species identified in this work are new records for mangrove fungus in the Southern of Bahia.
