RESUMO
Polysaccharides from wood-rooting fungi have attracted attention due to their broad pharmacological properties. Herein, we report the antitumor and immunomodulatory activities of acid polysaccharides isolated from fungi Gloeosoma mirabile. The polysaccharide extracts displayed significant antiproliferative activity against cancer cell lines (MCF-7, HCT-116, U-937) in a dose-dependent manner and induction of IL-6 in macrophage RAW 264.7. Furthermore, flow cytometry analysis showed that high polysaccharide concentrations induced apoptosis by 83% in HL-60 cells. Based on gas chromatography-mass spectrometry (GC-MS) and Fourier transform infra-red (FT-IR) spectroscopy studies, acidic polysaccharides from G. mirabile were mainly composed of arabinose, α-D-galactopyranose and methyl ß-D-galactopyranoside.
RESUMO
The fear of environmental doom (eco-anxiety) is a new and growing source of mental distress that could particularly affect the next generation of conservation biologists. With care and empathy, educators can help to prevent worsening the mental health of students.

Phlebopus is a genus of boletoid fungi that produces conspicous basidiomes with large dimensions. The genus is represented in Brazil by six species distributed in eight States, with P. beniensis being here newly reported from the State of São Paulo, Southeastern Brazil. Therefore, the aim of this study is to report the occurrence of this species in São Paulo State based on specimens from Southwestern region of the State, as well as to present ethnomycological notes, including the first report of the species edibility.
Phlebopus é um gênero de fungos boletoides que produz basidiomas conspícuos, de grandes dimensões. O gênero está representado no Brasil por seis espécies distribuídas em oito Estados, porém, P. beniensis ainda não havia sido registrada para o Estado de São Paulo, Sudeste do Brasil. Sendo assim, o objetivo deste trabalho é registrar a ocorrência da espécie para o Estado de São Paulo com base em espécimes da região sudoeste do Estado, assim como apresentar notas etnomicológicas, incluindo o primeiro registro de comestibilidade da espécie
RESUMO
The knowledge about gasteroid fungi in Brazil have increased considerably during the last two decades. However, there are still areas in the country where no species reported, and on the other hand, there are species that were reported only from a few localities. About 70 species of gasteroid fungi are reported from the State of São Paulo (Southeastern Brazil), but this number may be increased with more collections and studies. The aim of this article is to report for the first time the occurrence of nine gasteroid species from São Paulo: Calvatia fragilis, C. guzmanii, Cyathus julietae, Geastrum argentinum, G. minimum, G. violaceum, Phallus glutinolens, Scleroderma areolatum and Vascellum pampeanum. The latter is also a new report from Brazil. Moreover, additional comments are provided for the species Abrachium floriforme, Arachnion album and Phallus rubicundus.
O conhecimento acerca da diversidade e distribuição de fungos gasteroides aumentou consideravelmente durante as últimas duas décadas. Entretanto, ainda há regiões no país onde não existem registros de ocorrência desses organismos, e por outro lado, há espécies que foram registradas apenas para poucas localidades. Cerca de 70 espécies de fungos gasteroides são listadas para o Estado de São Paulo (Sudeste brasileiro), porém esse número pode ser aumentado com um maior esforço de coletas e estudos. O objetivo deste artigo é registrar pela primeira vez a ocorrência de nove espécies para o Estado de São Paulo: Calvatia fragilis, C. guzmanii, Cyathus julietae, Geastrum argentinum, G. minimum, G. violaceum, Phallus glutinolens, Scleroderma areolatum e Vascellum pampeanum, sendo que essa última também representa um novo registro para o Brasil. Ainda, comentários adicionais são apresentados para as espécies Abrachium floriforme, Arachnion album e Phallus rubicundus.
RESUMO
Fuscoporia bifurcata is described from southern Brazil based on collections from mangrove areas on Santa Catarina Island, in the state of Santa Catarina. The new species is characterized by hymenial setae with a bifurcate or spiny apex. A description with illustrations, an updated key to species of Fuscoporia from southern Brazil and a key to species of Hymenochaetaceae reported from mangroves are provided.
