Interpretive Summary:

Technical Abstract: Morphological and molecular characters (DNA) are used at all taxonomic levels; the two types of data are not always consistent. Morphology-based hypotheses usually are supported. DNA characters indicate a circumscription of the order that conflicts with morphology and ontogeny. DNA characters confirm more than one family in the order. Holomorph genera aindicated by DNA usually conform to morpholgical hypotheses, but not always. DNA indicated inclusion of asexual fungi into the botanical system and also indicated natural anamorph gnera. Anamorph sections are often paraphyhletic but taxonomicaally useful. DNA indicated clonal species and radiation of anamorphs within a teleomorph form, which confuse species definition.
