Interpretive Summary: Everything needs a name in order to effectively communicate about it, including fungi that cause plant diseases. Names of fungi are based on specimens preserved for future study in a reference collection. In some cases, these reference specimens have become lost due to mislabeling or relocation of the specimens from one reference collection to another. In this study, 71 reference specimens of Xylaria, a large group of plant-associated fungi, were located in the U. S. National Fungus Collections, illustrated and characterized with an identification key. The specimen records were updated to reflect all known information and filed under the correct names for ease of access in the future. This information will be used by scientists and plant quarantine officials who identify plant-associated fungi and need accurate scientific names to communicate about diseases caused by fungi and to keep American agriculture safe.

Technical Abstract: Seventy-one new Xylaria names that C. G. Lloyd proposed are annotated herein. Type and/or authentic materials of these names, when available, were studied. Twenty-four of these, including X. beccarii, X. brasiliensis, X. chordaeformis, X. cuneata, X. divisa, X. fimbriata, X. humosa, X. kedahae, X. luteostromata, X. luxurians, X. maumeei, X. morganii, X. muscula, X. nigrescens, X. nodulosa, X.papulis, X. partita, X. petchii, X. praefecta, X. radicans, X. reinkingii, X. reticulata, X. stromatica, and X. theissenii, are considered correct names for distinct species, and four of these, including X. bipindensis, X. clavus, X. cuspidata, and X. muscandae, are for probably distinct species. Illustrations for these species are provided. Thirty names are treated as synonyms or probable synonyms of those published earlier. Thirteen names remain uncertain to us because their type materials are immature or lacking fungal elements except for X. stromafera, of which we were unable to study the type material. A cross-index and an identification key to the Xylaria names that Lloyd proposed are also provided.
