A new species of Neoarthrinium is described from Brazil based on morphological and molecular analyses. During endophyte
collection in the cocoa area of the agroecosystem (Cabruca), Neoarthrinium brasiliense was obtained from the leaves of Lafoensia
pacari. Morphological characteristics and multi-gene phylogenetic analyses based on the DNA sequences of the internal transcribed
spacer (ITS), 28S rDNA region (LSU), and tubulin (TUB2) showed that N. brasiliense was distinct from other species of
the genus. The new species is morphologically characterized by its ampulliform, doliiform, or cylindrical conidiogenous cells, by
conidia acroperogens singly or in chains forming clusters, with varied shapes and longitudinal germ slit. A key to the Neoarthrinium
species is also provided.
