... About 6480 species of fungi are known in Brazil, and this diversity is still little explored in the Cerrado [7]. However, studies from the last decade have shown that the biome has a rich diversity [8][9][10]. Nevertheless, the increasing devastation of the biome, mainly due to agribusiness, has been worrying and has affected biological diversity [11][12][13]. ...
... Despite the participants showing that they perceive the presence of fungi in the environment in which they live, several traditional morphological fungi groups commonly found in the Cerrado, such as poroid (bracket fungi) [9], jelly fungi [8] and gasteroid fungi (puffball, stinkhorn, among others) [10] were not represented in the drawings produced. On the other hand, there was emphasis on mushrooms, indicating that the perception of fungi among most students may be restricted to this morphological group. ...
Background
Environmental perception involves the interpretation and interaction of individuals with their surroundings, influenced by cultural, social, and individual factors. Analyzing the environmental perception of children and adolescents contributes to fostering awareness and ethical behavior toward the environment. Indigenous communities, such as the Karajá from Brazil, possess significant environmental knowledge due to their connection with nature, providing distinctive insights into biodiversity and natural interconnections. In this study, the perception of fungi among Karajá indigenous children and adolescents was investigated.
Methods
The study involved 229 elementary school students from the Macaúba, Fontoura and Santa Isabel do Morro communities, located on Bananal Island, Brazil. Students were encouraged to draw what they knew about fungi and answer where they learned about fungi and what name they give to these organisms. The drawings were analyzed considering seven categories.
Results
The term most used to refer to fungi was hedoro(u) (56%), followed by fungus (21%) and mushroom (11%). Most students said they had learned about fungi in nature (38%) and at school (36%). The most represented organisms were in fact fungi (93%), mainly being portrayed in nature (94%). Most participants did not attribute any ecological function to fungi (83%), although 16% of them recognized fungi as decomposers and 1% as phytopathogenic agents. Negative aspects, particularly food contamination, were more frequently represented (13%) than positive aspects (4%). The drawings identified two morphological types: mushrooms (87%) and mold (13%). Among these mushrooms, 68% possibly represent the Amanita muscaria species.
Conclusions
Although the children and adolescents showed that they noticed the fungi around them, the group’s concept and understanding were limited to the figure of the mushroom and the negative aspects related to food contamination. Strong association of the fungi with the A. muscaria is noteworthy, since it does not occur in the environment in which the participants live, suggesting that external stimuli, such as TV or the internet, can influence their perception more than the nature they are exposed to.
... The known biodiversity of PESCAN comprises more than 800 species, including plants, vertebrate animals, insects, amoeboid protists (Myxomycetes), and fungi (Alvarenga & Xavier-Santos 2017, Moreira & al. 2019, SEMAD 2021. Among these groups of organisms, the fungi are one of the poorer known with only 10 species of macrofungi (Alvarenga & al. 2015, Calaça & al. 2015, Calaça & Xavier-Santos 2016, Alvarenga & Xavier-Santos 2017, Leonardo-Silva & al. 2020, which supports the need for more sampling efforts in the region. ...

A list of 51 species composes this inventory, six of them reported for the first time from Cerrado Biome (Flabellophora parva, Hymenochaete microcycla, Navisporus sulcatus, Stiptophyllum erubescens, Trechispora mellina, and Truncospora ohiensis), five from the Midwest region of Brazil and two from Goiás. These results increase sampling efforts and knowledge about these fungi in this little-studied region of Brazil.
... Although the REC-UEG suffers a strong environmental impact due to its location, it is still possible to observe expressive biodiversity that resists. Besides the richness of corticioid and poroid fungi that we reported, previous studies in the area also presented new occurrences for the Cerrado (Alvarenga & Xavier-Santos 2017, Camilo-Cotrim et al. 2020, Ferreira-Sá et al. 2023. Thus, the number of specimens collected over the years, as well as the species richness shows the importance of preservation for regional Funga representativeness. ...
Corticioid and poroid fungi are traditional morphological groups composed of ligninolytic species. Due to their efficiency in wood decomposition process, many species have great ecological importance, especially in nutrient cycling, as well as for their biotechnological properties. Nevertheless, knowledge about these fungi is scarce in many phytogeographic regions of Brazil, as is the case of the Cerrado, since mycodiversity studies in this biome are mainly focused on areas of the São Paulo state. Here we present the taxonomic inventory of corticioid and poroid fungi from the Reserva Ecológica da Universidade Estadual de Goiás (REC-UEG), a Cerrado remnant in Anápolis, Goiás, Brazil. The area is covered by three typical Cerrado landscapes (cerrado stricto sensu, mesophilic forest, and gallery forest), widely explored for scientific and educational purposes by the academic and regional community which seeks to learn about and preserve its biodiversity. Exsiccates deposited in the fungarium of the Universidade Estadual de Goiás (HUEG-Fungi) were analyzed. They are the result of collections made over 20 years, in approximately 103 ha of the reserve. Samples were characterized macro and microscopically and identified based on specialized literature. 51 species were recognized, which are distributed in 33 genera, 15 families, and five orders. Species were most frequent in forested areas and among them, six are new occurrence records for the Cerrado, nine for the Midwest region, and nine for the Goiás state. These results contribute to increase the knowledge of these fungi in the Cerrado, as well as geographic distribution, and show the relevance of preserving the reserve for the regional Funga representativity.
... We recommend that studies based on both morphological and multigene phylogeny must be carried out, including on type material and sequences from Neotropical species, to best clarify the taxonomic status of species with spinose hymenophores, such as Hydnum and Hydnum-like fungi. Fidalgo et al. (1965) presented the first survey of macroscopic fungal diversity in the Brazilian Cerrado, and since then, some areas of this ecosystem have been explored further (Gibertoni and Drechsler-Santos 2010;Alvarenga et al. 2015Alvarenga et al. , 2017Calaça et al. 2018Calaça et al. , 2020Leonardo-Silva et al. 2020. Here, with our discovery of G. sacchari, we report the first occurrence of the genus Gyrodontium in the Brazilian Cerrado, as well as the first record of the family Coniophoraceae in the Midwest Region of the country. ...
We report the first occurrence of the genus Gyrodontium Pat. from the Brazilian Cerrado based on our finding of G. sacchari (Spreng.) Hjortstam. This also represents the first record of the family Coniophoraceae from the Midwest Region of central Brazil. We identified the sample by morphological and phylogenetic analyses (ITS gene), and a voucher was deposited in the fungarium of the Universidade Estadual de Goiás (HUEG-Fungi). This record adds to the knowledge of the Cerrado's funga by providing new phylogenetic and biogeographic data for G. sacchari from a Neotropical region.
... Recently, some Dacrymyces species have been described using molecular and morphological data (Shirouzu et al. 2009(Shirouzu et al. , 2017. So far, 29 species have DNA sequences usually from nuclear ribosomal internal transcribed spacer (ITS) and large subunit (LSU) rDNA regions (Shirouzu et al. 2009(Shirouzu et al. , 2017Zamora and Ekman 2020 (Lowy 1971;Sobestiansky 2005;Meijer 2016;Alvarenga and Xavier-Santos 2017;Castro-Santiuste et al. 2017), although none of them was confirmed using molecular data and most are represented by one record. Thus, species recognition in the genus remains problematic, mostly those from the Neotropics. ...

The class Dacrymycetes has two orders (Dacrymycetales and Unilacrymales), four families, and 13 genera, few of them with available molecular data and then usually of dubious delimitation. Dacrymyces Nees is a polyphyletic genus in Dacrymycetes and was introduced to accommodate one species, D. stillatus Nees, being characterized by a homogeneous composition of the intra-structure and an amphigenous or superior hymenium. In this study, neotropical specimens were added in the phylogeny of the Dacrymycetes, and as a result, Dacrymyces s.s. is emended to include species with resupinate basidiomata, unilateral hymenium, heterogeneous context, and absence of clamp connections. In this new delimitation, the new species Dacrymyces flavobrunneus sp. nov. is described using morphological and molecular data, two new combinations (D. maxidorii comb. nov. and D. spathularia comb. nov.) are proposed based on DNA analyses, and previous combinations and new species (Dacrymyces burdsallii, D. ceraceus, D. cereus, D. confluensunilateral, D. corticioides, D. grandii, D. grandinioides, D. lagerheimii, D. pulchrus, D. sobrius, and D. venustus) are formally included in the genus circumscription.

O Cerrado alberga uma enorme variedade de organismos, incluindo a microbiota, que ainda é pouco conhecida pela ciência. Pontuar evidências ciêntíficas que retratem a riqueza e abundância dos microrganismos existentes nesse bioma é importante não somente para estimular mais pesquisas bioprospectivas que demonstrem as pontecialidades biológicas presentes na região, mas também atitudes conservacionistas e sustentáveis. A presente revisão teve por objetivo destacar relatos de novas espécies fúngicas descobertas recentemente no bioma Cerrado. Foi realizada pesquisa exploratória com o levantamento de artigos em inglês e português publicados entre nos anos de 2015 a 2019, nas bases Google Acadêmico, Scielo, Portal Capes e DOAJ, empregando-se os descritores “fungos do cerrado”, “(bio)prospecção de fungos do cerrado” e “novas espécies de fungos no cerrado”. Na busca foram considerados somente artigos que relatassem descobertas de novas espécies para a comunidade científica ou primeiro relato de uma determinada espécie no bioma Cerrado, bem como primeira associação evidenciada de determinado fungo a outros organismos, podendo tais relatos indicarem ou não possíveis aplicações biotecnológicas dos organismos encontrados. Artigos não enquadrados nos critérios de inclusão foram excluídos da busca. Foram verificadas pesquisas com relatos de novas descobertas em especial nos estados de Goiás, Minas Gerais, Mato Grosso e Mato Grosso do Sul. Algumas das descobertas evidenciaram possíveis propriedades biotecnológicas dos isolados encontrados, envidenciando a necessidade de ações que visem não somente a conservação do bioma, como também mais pesquisas bioprospectivas.
A taxonomical revision of the Dacryopinax species in Mexico is presented in detail. Historically, only four species were known in the country: Dacryopinax elegans, D. lowyi, D. spathularia, and D. yungensis. Dacryopinax martinii is reported for the first time from Mexico. Taxonomical descriptions and remarks for all the species, based on macro- and micro-morphology, as well as geographical distribution are included, except for D. yungensis, as its record corresponded to a misidentification of D. spathularia. We propose a new phylogeny including the taxonomic position and relationships of all species, based on ITS and LSU sequence data. Finally, a dichotomous key to identify the four species in Mexico is provided.
