Interpretive Summary: Fungi are a group of organisms that cause billions of dollars damage each year to agricultural and forest resources in the United States. One group of fungi includes the species that caused chestnut blight in the eastern United States. Many additional fungi belong to the same group some of which have only recently been discovered. This research describes and illustrates seven new species of fungi that belong to the group of fungi that includes chestnut blight. Many of these species occur on hardwood trees in both eastern Asia and North America. This paper will be used by forest pathologists to determine the species of fungi that occur on hardwood trees.

Technical Abstract: Seven undescribed diaporthalean species were found in different regions of eastern Asia and eastern North America. Three of these new species and one previously known species are assigned to a new genus Leucodiaporthe. Descriptions and illustrations are provided for the new taxa including Allantoporthe leucothöes sp. nov., Diaporthella corylina sp. nov., Leucodiaporthe acerina sp. nov., L. juglandis sp. nov., L. maackii comb. nov., L. robiniae sp. nov., Leucostoma pseudoniveum sp. nov., Leucostoma excipienda comb. nov., and Phragmodiaporthe padi sp. nov.
