Magnago AC, Trierveiler-Pereira L, Neves MA 2013 – Contributions towards the knowledge of Favolaschia (Mycenaceae, Agaricomycetes) from Brazil. Mycosphere 4(6), 1071–1078, Doi 10.5943/mycosphere/4/6/5 Abstract Favolaschia is a representative genus in the Brazilian Atlantic Forest where four species have been recently identified: Favolaschia cinnabarina, F. dealbata, F. rubra and F. selloana. Favolaschia dealbata is a new record for Brazil and F. selloana is new for Southeastern Brazil. Color images of the basidiomata, complete descriptions and illustrations of the four species are presented. Key words – Agaricales – fungal taxonomy – neotropical mycota Introduction Favolaschia (Pat.) Pat. is a genus of usually small, mushroom-like basidiomycetes that occur worldwide, especially in the tropics. Members of the genus are often characterized by their poroid hymenophore, amyloid spores, frequent presence of gloeocystidia and acanthocystida and a trama that is usually gelatinous (Gillen et al. 2012). Favolaschia comprises approximately 50 species (Singer 1974, Parmasto 1999, Kirk et al. 2008) and about 20 of these have been reported for Brazil (Gillen et al. 2012). The first records of the genus in Brazil are from the nineteenth century (e.g. Spegazzini 1889, Bresadola 1896, Hennings 1897). More recent records include the description of a new species, F. luteoaurantiaca Capelari, Karstedt & J.S. Oliveira (Singer 1974, Singer & Fidalgo 1965, Capelari et al. 2013). Although Favolaschia species are very common in the Brazilian Atlantic forests, few species have been reported from the state of Santa Catarina, in Southern Brazil: F agaricina (Mont.) Kuntze, F. cinnabarina (Berk. & M.A. Curtis) Pat., F. flava (Bres.) Kuntze, F. moelleri (Bres.) Singer and F. rubra (Bres.) Kuntze (Bresadola 1896, Capelari et al. 2013). This article presents descriptions and illustrations of four Favolaschia species recently identified from Southeastern (Espírito Santo State) and Southern Brazil (Santa Catarina State). Favolaschia dealbata is a new record for Brazil and F. selloana is a new record for Southeastern Brazil and the first record of the genus for the state of Espírito Santo (Vinha 1988).
