XVI International Botanical Congess

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/ontogeny. DNA characters confirm more than one family in the order. Holomorph genera indicated by DNA usually conform to morphological hypotheses, but not always. DNA indicates inclusion of asexual fungi into the botanical system and also indicates natural anamorph genera. Anamorph sections are often paraphyhletic but taxonomically useful. DNA indicates clonal species and radiation of anamorphs within a teleomorph form, which confuse species definition.
