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. Additionally, other 150 species represent taxa with unclear evidence of consumption or unconfirmed edibility status. A total of 86 of the 409 edible species represents consistent records in Brazil based on molecular data and/or Brazilian nomenclatural types. Other 323 names represent species that need further taxonomic investigations to confirm their identity and occurrence in the country, with 41 of them having some record of consumption by part of the Brazilian population. The remaining 282 species can represent new food resources for the country. We generated 143 DNA sequences, representing 40 species within 29 genera. Edible mushrooms are an important non-wood forest product and the knowledge about them adds value to the local biodiversity and the population, increasing the incentive to conservation allied to sustainable rural development.
