Technical Abstract: The fungal family Gnomoniaceae (Diaporthales) has been traditionally considered to include genera with species that grow exclusively on leaves of herbaceous pants and hardwood trees principally from temperate zones of the Northern Hemisphere. However, recent molecular data has shown that there are a number of species that infect woody tissues, currently excluded from the Gnomoniaceae on the basis of morphology, that are highly supported to belong to this family on the basis of multiple gene sequence analysis. This work present a reviewed taxonomy and phylogenetic placement for available species from the genera Amphiporthe, Cryptosporella, Cryptodiaporthe, and Ditopella, all of them known to occur mostly on woody tissues. We confirm the placement of the type species of these genera within the Gnomoniaceae and present phylogenetic analyses at the genus level based on multiple gene data analysis. Furthermore we will present information on the relationship between host identity and the speciation patterns and geographic distribution of these fungi.
