Ophiodothella angustissima comb. nov., a new name for Acerviclypeatus poriformans and O. vaccinii

Abstract

A common leaf spot disease on Vaccinium arboreum in the southeastern United States has been attributed to Ophiodothella vaccinii. The leaves are infected in early spring and during the summer abundant acervular conidia are produced. In addition to O. vaccinii, two names have been applied to this fungus in the literature, Septoria angustissima and Acerviclypeatus poriformans. A study was undertaken to determine which name should be applied to this fungus, resulting in our proposing a new combination. On the basis of priority, O. angustissima comb. nov. is the correct name for the taxon.
