Abstract
Abstract 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.

As coletas foram realizadas na Estação Ecológica Raso da Catarina e as análises ocorreram no Laboratório de Ciências, da Universidade do Estado Bahia, Campus VIII, Paulo Afonso
Given the information above and the relevance of this question, the objective of this study was to document the first occurrence of A. nigeriensis Stchigel Guarro to the American continent, colonizing the Syagrus coronata palm and increasing the distribution data on the representatives of this genus, providing new information for Brazilian mycological biodiversity
Summary
Apiosordaria is a genus of fungus with species commonly reported inhabiting soil or herbivore feces. Neste trabalho documentamos uma nova ocorrência para o Brasil de uma espécie de Apiosordaria, associada a palmeira Syagrus coronata. Ascospores with 2 cells or occasionally 3, with upper cell blackish, ellipsoidal to subglobose, dark-brown to black, with ornamentation and germinative pore; lower cell triangular to cylindrical, hyaline and smooth (Stchigel et al 2000).
