O ensino de entomologia no ensino básico tem sido um grande desafio para os educadores. O uso do livro didático tem sido a ferramenta mais utilizada, resultando em pouca aderência dos alunos às atividades propostas em sala de aula. Outras ferramentas, como os insetários, são bastante exploradas, porém a necessidade de manutenção constante e impossibilidade de manuseio por parte dos alunos deixa evidente a necessidade de busca por alternativas mais interessantes que proporcionem um melhor aprendizado para os alunos. O trabalho traz o passo-a-passo para a elaboração blocos com insetos incrustados em resina, bem como sua aplicação em sala de aula.

A nogueira-pecan (Carya illinoinensis, Juglandaceae) foi introduzida no Brasil no início do século XX por imigrantes americanos e seu cultivo atualmente se estende desde o Rio Grande do Sul até Minas Gerais, com aproximadamente 2,4 mil hectares plantados. Apresenta-se o primeiro relato de mixomicetos associados à serapilheira de C. illinoinensis, diretamente observados no campo, esporulados sobre folhas secas (Physarum cinereum, P. melleum, P. polycephalum), gravetos e folhas secas (Diachea leucopodia) e galhos (Fuligo cinerea, F. septica, Hemitrichia serpula var. serpula). As espécies mais constantes foram P. melleum e D. leucopodia. Fuligo cinerea é registrado pela primeira vez para o Rio Grande do Sul; D. leucopodia e P. cinereum são citados pela primeira vez para a porção brasileira do Pampa, elevando para 61 o número de espécies conhecidas para o bioma.

Bryophilous fungi have at least one stage of its life cycle linked to Bryophytes. There are few studies in relation to their taxonomy and ecology all around the world, including Brazil. The Agaricomycetes (Basidiomycota) have gained prominence worldwide and contained several species of economic interest. Based on a bibliographic review and discussion about identification methods and experimental models on this association a species list of bryophilous/Agaricomycetes found in Brazil was elaborated. In the works found among the techniques used to identify effective fungi/Bryophytes associations it can be cited: phylogenetics analysis, optical and electron microscopy, and cultivation experiments. In Brazil, four orders of Agaricomycetes (Basidiomycota), belonging to Agaricales, Boletales, Hymenochaetales, and Polyporales, with 33 species were found associated to Bryophytes in the literature. Information of the worldwide distribution of Brazilian muscicolous species and application of these groups were realized associating edibility, toxicity, and others. It was noted that in this country there is a scarcity of scientific knowledge of this subject, that needs to be better understood in terms of ecology and taxonomy.

The study of Agaricomycetes in the Brazilian Pampa Biome is still incipient, but it is very necessary for the valorization and preservation activities in this area. In terms of fungal diversity, it is the least studied Brazilian biome, with only 84 species already described for the site, despite the great diversity of fauna and flora that this biome presents. The objective of this work is to know more about the mycodiversity of this biome, contributing to a better understanding of the distribution and ecology of the Agaricales. The collections were made following the usual methodology for Agaricales (Basidiomycota). Thus, specimens were collected for studies to identification to species level by macro- and microscopic characters. Descriptions of seven species collected in the rural region surrounding the city of São Gabriel, state of Rio Grande do Sul, Brazil are presented, which are cited for the first time for the Pampa Biome, namely: Macrolepiota mastoidea, Protostropharia alcis ssp. austrobrasiliensis, Trogia buccinalis, Crepidotus euterpicola, Entoloma depluens, Lepiota subincarnata and Neopaxillus echinospermus. These new citations reinforce the importance of studies on the biodiversity of the Pampa biome for its preservation.

Phaeosphaeria deschampsii was described from dead leaves of Deschampsia antarctica (Antarctic Grass). We surveyed other islands of the South Shetland archipelago, Antarctica, and also found Arctic Grass whitening, the disease associated with this fungus, indicating that is disease is widespread.

Foi realizada com duas turmas de terceiro ano do ensino médio uma saída de campo com uma visita a um local de floresta próximo a área urbana, para ver a realidade do que acontece com o lixo que jogamos fora sem estar interessado no que irá acontecer com ele. Foi coletada parte desse material e realizada a reutilização desses, transformando o material coletado em objetos de decoração, assim garantindo que aos alunos tenham consciência de que podemos reutilizar em vez de descartar.

In the second decade of the 20th century, Lycogala flavofuscum aethalia were collected in Brazil by Rev. Johannes Rick. Despite being easily observed in the field because of the size of the aethalia, the species was only found again in 2019, on a live trunk of Sebastiania commersoniana (branquilho, Euphorbiaceae) in the municipality of São Gabriel, Rio Grande do Sul, Brazil. The description and illustration of recently collected material, and data on exsiccates collected by Rick from Brazil, deposited at Herbarium BPI, are presented herein. Information on substrates, microhabitats, and geographic distribution of the species in the Neotropics is provided based on bibliographical sources and herbarium catalogs. Considering the large time interval between records and the restricted area of occurrence in the country, its inclusion as near threatened in the Brazilian Red List is recommended.
