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.
Mycotaxon is pleased to add to our 'web-list' page the following new annotated species distribution list under South America (Brazil): "Ascomycota (lichenized and non-lichenized) on Syagrus coronata in the Caatinga biome: new and interesting records for Brazil and South
America" by Maiara A.L. dos Santos, Nilo G.S. Fortes, Tássio E.F. Silva, Nadja S. Vitória. This brings to 133 the number of free access Fungae now available on our website: http://www.mycotaxon.com/mycobiota/index.html
Apiosordaria is a genus of fungus with species commonly reported inhabiting soil or herbivore feces. However, studies related to the association of representatives of this genus to plants, especially in semi-arid ecosystems, are still non-existent. In this work we documented a new occurrence for Brazil of a species of Apiosordaria, associated with the palm Syagrus coronata. The collections were carried out at the Raso da Catarina Ecological Station and the analyzes were carried out at the Laboratory of Sciences of the Bahia State University, Campus VIII, Paulo Afonso. From the topographic analysis of the plant substrate in stereomicroscope and the evaluation of fungal structures under optical light microscope, the species was identified as Apiosordaria nigeriensis. This fungus was reported for the first time in Enugu, Nigeria, after being isolated from soil samples. In this work, we report the second occurrence of A. nigeriensis to the world, being the first to Brazil, representing the first record for the Americas, and highlighting the palm S. coronata as the first botanical host colonized by the species. These data broaden the knowledge about the geographic distribution of the genus, especially on the microdiversity for the caatinga biome.
