Previous issue date: 2014-02-19 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / O Brasil ? um pa?s de grande biodiversidade e possui potencialmente 20% de toda biodiversidade mundial. Diante deste quadro, o conhecimento sobre a micobiota brasileira ? escasso e isso se agrava em regi?es como o semi?rido brasileiro. O presente trabalho teve como objetivo investigar as esp?cies de fungos da fam?lia Russulaceae para o semi?rido, atrav?s de estudos taxon?micos. As coletas foram realizadas durante o per?odo chuvoso, em ?reas de conserva??o de alguns estados do Nordeste. Os materiais foram descritos, ilustrados macro e microscopicamente, juntamente com as an?lises da ornamenta??o de esporos, estes foram obtidos com microsc?pio eletr?nico de varredura e outras microestruturas de cunho taxon?mico. Como resultado foram encontradas 12 esp?cies. O g?nero mais rico ? Russula com sete esp?cies, Lactifluus com quatro e por fim Lactarius com uma esp?cie. Todas as esp?cies s?o novas para a ci?ncia, aumentando o conhecimento sobre a riquesa de Russulaceae no Brasil de 41 para 52 esp?cies, este presente trabalho representa 4,5% da riqueza de t?xons conhecidos para o Brasil e evidencia que o semi?rido ? uma ?rea rica para estudos taxon?micos desta fam?lia. / Brazil is a country with a big biodiversity and has a 20% of all biodiversity of the world.
Therefore the knowledge of the brasilian mycobiota e scarce and it?s worse in the semiarid
region. The present study intended to investigate the species of fungi of the Russulaceae of
Caatinga through taxonomic studies. The collections were made during the rainy season in
areas of conservation of some Northeastern states. The species were discribed, ilustraded
macro- and microscopically, microstructures of taxonomic aspects and spores
ornamentations, these were also observed in scanning electron microscopy. As result were
described 12 species. The most representative were Russula with 7 species, Lactifluus with
4 species and Lactarius with 1 species. All the species are new to science, this rase de
diversity of Russulaceae from 41 to 52 species, this work represents 4,5% of de diversity of
t?xons known for Brazil and shows that the semiarid region is relevant in study of this
family. / 2018-06-20
