Abstract
Sympoventuriaceae ( Venturiales, Dothideomycetes) comprises genera including saprophytes, endophytes, plant pathogens, as well as important animal or human opportunistic pathogens with diverse ecologies and wide geographical distributions. Although the taxonomy
of Sympoventuriaceae has been well studied, generic boundaries within the family remain poorly resolved due to the lack of type materials and molecular data. To address this issue and establish a more stable and reliable classification system in Sympoventuriaceae, we performed
multilocus phylogenetic analyses using sequence data of seven genes (SSU, ITS, LSU, act1, tub2, tef1 and rpb2) with increased taxon sampling and morphological analysis. The molecular data combined with detailed morphological studies of 143 taxa resolved 22 genera
within the family, including one new genus, eight new species, five new combinations and one new name. Finally, we further investigated the evolutionary history of Sympoventuriaceae by reconstructing patterns of lifestyle diversification, indicating the ancestral state to be saprophytic,
with transitions to endophytic, animal or human opportunistic and plant pathogens.
