Over 400 food resources from Brazil: evidence-based records of wild edible mushrooms.

Many species of mushroom-forming fungi have been harvested in the wild and used for food and medicine for thousands of years. In Brazil, the knowledge of the diversity of wild edible mushrooms remains scattered and poorly studied. Based on new samples, bibliographic records revision, and searches through the GenBank, we recorded 409 species of wild edible mushrooms in Brazil, of which 350 can be safely consumed and 59 are edible but with conditions.

Adapt conservation biology teaching to address eco-anxiety in students.

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.

Antibiofilm activity of propolis extract on Fusarium species from onychomycosis.

Aim: The present study evaluated the capacity of three species of Fusarium isolated from onychomycosis to form biofilms and the antibiofilm effect of propolis extract on these biofilms.

Materials & Methods: The biofilms and antibiofilm effects were evaluated by quantifying the colony-forming units, mitochondrial metabolic activity assays, total biomass by crystal violet staining and scanning electron microscopy.

Results: Propolis extract demonstrated significant antibiofilm efficiency on Fusarium spp.

Sequestrate fungi from Patagonian Nothofagus forests: Cystangium (Russulaceae, Basidiomycota).

Six species of Cystangium, a genus of sequestrate taxa related to Russula, were collected in Patagonia (Argentina and Chile) during autumn 2001. Two species, C. depauperatum Singer & A.

Multigene phylogeny of the Phallales (Phallomycetidae, Agaricomycetes) focusing on some previously unrepresented genera.

Phylogenetic relationships within the Phallales were estimated via combined sequences: nuclear ribosomal large subunit (LSU), second largest subunit of RNA polymerase (rpb2), and mitochondrial ATPase subunit 6 (atp6). The ingroup is represented by 62 taxa comprising 18 genera and 44 species, including members of the Clathraceae, Claustulaceae, Gastrosporiaceae, Lysuraceae, Phallaceae and Protophallaceae. Sixty-one new sequences were generated, including tropical and subtropical taxa.

Santa Catarina Island mangroves 3: a new species of Fuscoporia.

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.
