Families of<i>Diaporthales</i>based on morphological and phylogenetic evidence

Abstract

<i>Diaporthales</i> is an important ascomycetous order comprising phytopathogenic, saprobic, and endophytic fungi, but interfamilial taxonomic relationships are still ambiguous. Despite its cosmopolitan distribution and high diversity with distinctive morphologies, this order has received relativelyiaceae, <i>Macrohilaceae</i>, <i>Melanconidaceae</i>, <i>Pseudoplagiostomaceae</i>, <i>Schizoparmaceae</i>, <i>Stilbosporaceae</i> and <i>Sydowiellaceae</i>. Taxonomic uncertainties among genera are also clarified and recurrent discrepancies in the taxonomic position of families within the <i>Diaporthales</i> are discussed. An updated outline and key to families and genera of the order is presented.
