Interpretive Summary: A fungus was discovered that has potential to control the invasive weed known as purple loosestrife. At first the name of the fungus could not be determined, but later the fungus was given a new name. The placement of the fungus with close relatives is now known to be wrong. Based on an examination of the microscopic structures of the purple loosestrife fungus and a similar species, the two fungi are placed in the same genus. This research will be used to discover more fungi from around the world that may be useful in the biological control of invasive weeds.

Technical Abstract: The coelomycete Dwiroopa was determined to be the correct genus for Harknessia lythri and the new combination is made. The type species, D. ramya, is described and illustrated based on the type specimen for which a lectotype is designated. A key to the two species of Dwiroopa is presented along with a discussion of their similarities and differences. In addition the relationship between Dwiroopa and Harknessia is considered.
