Interpretive Summary:

Technical Abstract: The ascomycete order Diaporthales includes a number of plant pathogenic fungi, the most notorious of which is Cryphonectria parasitica, the chestnut blight fungus. Relationships among genera in the Diaporthales were evaluated as a basis for the recognition of families and to provide a taxonomic framework for the asexually reproducing diaporthalean fungi. Major lineages within the Diaporthales were determined by sequence analysis of the large subunit (LSU) of the nuclear ribosomal DNA. Results suggest the presence of at least six lineages within the Diaporthales. These lineages are recognized as the Gnomoniaceae sensu stricto that may or may not include the Melanconidaceae sensu stricto, the Schizoparme complex that could be recognized as the Sydowiellaceae, a newly proposed family (in this work or by someone else?) that includes the Cryphonectria-Endothia complex, the Valsaceae, the Diaporthaceae and the Pseudovalsaceae. In addition a number of teleomorphic and anamorphic taxa fall within the Diaporthales but were not allied with any of the major lineages.
