Original Article


Two initially unidentifiable isolates were found when endophytic fungi from healthy leaves of Myracrodruon urundeuva (Anacardiaceae) were being investigated in Brazil. Based on phylogenetic analyses using internal transcribed spacer (ITS) and partial large subunit (LSU) of ribosomal DNA, RNA polymerase II (RPB2), translation elongation factor EF-1 alpha (TEF1), and tubulin (TUB2), the isolates were identified as members of the family Pseudoplagiostomataceae (Diaporthales). In this paper, we introduce a new species, Pseudoplagiostoma myracrodruonis, thus accepting eight species in Pseudoplagiostoma (Pseudoplagiostomataceae). The new species is proposed to accommodate endophytes characterized by a coelomycetous asexual morph, pycnidial conidiomata with lageniform to ampulliform and hyaline to pale brown phialidic conidiogenous cells that produce unicellular, ellipsoid to oblong-cylindrical, hyaline, and guttulate conidia. In the current phylogenetic analysis, P. myracrodruonis is placed in a well-supported clade in Pseudoplagiostoma (Pseudoplagiostomataceae). A discussion about the relationship of Pseudoplagiostoma species is included in the paper.
