Checklist of Amazonian gasteroid fungi (Agaricomycetidae, Phallomycetidae, Basidiomycota)

Abstract

The Amazon rainforest is the largest tropical rainforest in the world, with high biodiversity of organisms. Despite the increasing knowledge about fungal diversity in the last few years, many fungal taxa, including gasteroid clades, are still poorly known. Gasteroid fungi are recognized by the maturation of basidiospores inside the basidiomata and by the passive release of spores. We conducted a detailed survey of published data on the species that occur in Amazon forests. We confirmed the occurrence of 83 species distributed in 22 genera, eight families and four orders. The most representative genera was Geastrum, followed by Cyathus, Lycoperdon and Phallus. We present an identification key for Amazonian gasteroid genera and a map of record distribution. This review is expected to contribute to identify distribution gaps for further research on gasteroid fungi and to subsidize policies for the conservation of fungi in the Amazon region.

Biodegradation and reduction of toxicity of Azo Trypan Blue dye by Amazonian strains of gasteroid fungi (Basidiomycota)

“…A portion of the basidiomycetes corresponds to gasteroid fungi, widely distributed in the tropics (Mueller et al, 2007), mainly in Brazil, where the diversity of the group increases every year (Accioly et al, 2019;Assis et al, 2022;Ferreira-Sá et al, 2021;Freitas et al, 2023;Santana & Couceiro, 2023). Studies with this group revealed the production of important substances with proven biological activity (Liu & Zhang, 2004;Dore et al, 2007;Coetze and Van Wyk, 2009), but there is a study gap regarding the discoloration of synthetic dyes.…”

New records of Geastrum (Geastrales, Basidiomycota) for the Amazon

“…It has a cosmopolitan distribution (Kasuya et al 2012) and is considered one of the most diverse genera of gasteroid fungi, with 100 to 120 currently valid species worldwide (Zamora et al 2014). In Brazil, 67 species of Geastrum were recorded in the latest review by Accioly et al (2019), and 30 species were recorded in the Amazon (Assis et al 2022).…”
