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.

Objective: The present work aimed to describe, comment, and illustrate two new lichenized species of Ascomycota. Method: Morphological analyses of the samples were performed at the Laboratory in the State University of Bahia (UNEB), Campus VIII. The lichen thalli were observed using a stereomicroscope (Zeiss); chemical treatments were performed to observe the microscopic structures of the lichens after exposure to 10% KOH (potassium hydroxide), lactophenol (cotton blue), Melzer’s reagent, chlorine, and viewed under UV light. The chemical compositions of the lichen were examined using thin layer chromatography (TLC) at the Biochemical Laboratory of the Federal University of Pernambuco. Results and conclusion: Stirtonia juaensis and Cryptothecia paramacrocephala are two new lichenized species of Ascomycota found colonizing the plants Spondias tuberosa Arruda (Umbuzeiro) and Piptadenia moniliformis Benth. (Quipembe) in the Caatinga phytogeographical domain near the village of Juá in the municipality of Paulo Afonso, within the Raso da Catarina Ecoregion in northern Bahia State, Brazil. Originality/value: Research related to lichen taxonomy in Brazil is still scarce, especially in the Caatinga. The new species of Stirtonia and Cryptothecia described and illustrated in this work expand the knowledge about fungi in Brazil.

Objective: The study aimed to identify the endophytic fungi present in fruits of S. coronata (licuri) through sequencing of the ITS (Internal transcribed spacer) region. Theoretical framework: The Syagrus coronata palm tree, known as licuri, plays a significant role in the Caatinga, both in socioeconomic and cultural terms. The fruits of this plant host several types of fungi, including saprophytes, phytopathogens, and endophytes. The complexity of fungi taxonomic identification, due to the diversity and morphological similarity between distinct taxa, often requires the use of molecular biology as an essential tool for accurate characterization. Method: The study used 14 isolates of endophytic fungi from fruits of S. coronota (licuri) preserved in the Mycoteca of the Mycology Laboratory of the Universidade do Estado da Bahia/DEDC - Campus VIII, Paulo Afonso. The DNA of these isolates was extracted to perform PCR (Polymerase Chain Reaction) using the primers ITS1F and ITS4. The PCR products were sequenced and analyzed with the Blastn tool, revealing 98 to 100% similarity in the accessions. Results and conclusion: From the 14 isolates, four presented themselves as Chlamydospores and one as Mycelia sterilia, making morphological identification unfeasible, and four were from taxa without taxonomic identification. The taxa identified using ITS region sequencing belong to the genera Curvularia, Diplodia, Fusarium, Lasiodiplodia, Neodeightonia, and Penicillium. Research implications: This study highlights the importance of using molecular techniques to complement the taxonomy based on morphological markers. Originality/value: The primary purpose of this study was to use the ITS region as a tool for identifying endophytic fungi in licuri fruits, since in the literature the mycota of this botanical substrate, which is a biocultural heritage of Bahia, is practically unknown.
