Interpretive Summary: Recent changes in the rules by which fungi are named have caused problems in knowing what to call some agriculturally or environmentally important fungi. Numerous papers have been published with recommendations on which name should be used for major groups of plant pathogens but some individual species have been overlooked. In this paper all known information is used to decide the correct names for three fungal species causing diseases of poplar trees. This work is significant because it will allow correct identification of these disease-causing fungi on an important group of trees. These results will be used by scientists and plant quarantine officials who need accurate scientific names to communicate about diseases caused by fungi.

Technical Abstract: Three species of Drepanopeziza that cause diseases of poplars have been known using scientific names for their sexual and asexual morphs, which is no longer allowed with the change to one scientific name for fungi. For each species, the oldest epithet is provided by the asexual morph; however, neither generic name available for the asexual morphs can be used for these species. As a result new combinations for these three species are required and accomplished by placing the oldest asexual morph epithet in the genus Drepanopeziza. The following new combinations are made: Drepanopeziza brunneum, D. castagnei, and D. populi.
