Mycota (Ascomycota) of Syagrus coronata (Mart.) Becc., Raso da Catarina Ecological Station, Brazil: new records

The Raso da Catarina Ecological Station (ESEC) is a conservation unit of integral protection located in the Caatinga biome, Northeastern Brazil, Bahia, between the cities of Paulo Afonso, Rodelas, and Jeremoabo. Among the botanical species of great relevance in the ESEC region stands out the palm Syagrus coronata (Mart.) Becc. (licuri). Currently, there is little information about the mycota that colonizes this host. Thus, this study analyzes the taxonomy of fungi occurring in S. coronata at ESEC Raso da Catarina. For that purpose, we conducted eight excursions between May 2014 and January 2015, in which we randomly demarcated and georeferenced 25 S. coronata plants. For the survey of the Ascomycota, we collected leaves, bracts, inflorescences, fruits, stem pieces and litter. We morphologically identified twenty-six taxa. Following an extensive literature research, we present dichotomous keys for genera, distribution data, and a checklist of fungi species, of which four are lichenized and 22 non-lichenized (nine anamorph/asexual and 13 teleomorph/sexual). These species belong to 26 genera and 18 families. We report Syagrus coronata in this study as a new botanical host for 22 fungi species.
