Abstract
Letendraeopsis palmarum, a new genus and species, is described in the Pleosporales, Tubeufiaceae, as an endophyte inhabiting internal tissue of leaves of the palm Euterpe oleracea. While it is not known to sporulate in nature and does not form an anamorph, L. palmarum produces abundant pallid ascomata in culture. The ascomata lack a preformed ostiolar opening.
