Abstract

Rust fungi (Pucciniales) comprise a large group of ecologically and economically important plant pathogens distributed globally where their hosts grow. The first published study of rusts in Indiana was carried out 131 years ago, and a revised checklist of all Pucciniales for Indiana has not been compiled since the works of Jackson from 1917 to 1920. Efforts to compile a checklist five years ago revealed a dire need for revision due to taxonomic and nomenclatural changes. We examined historical records, including online databases and literature, as well as new and historical collections in the Arthur Fungarium (PUR) at Purdue University. We provide an annotated checklist of all known species of rust fungi occurring in 90/92 Indiana counties. Names in prior records have been updated to reflect the current classifications for this group, with cross-reference to older names. A total of 301 Pucciniales taxa across 32 genera and their host species have been verified. This work serves as a resource for statewide plant disease diagnosticians and records the extant rust fungal biodiversity in Indiana to guide research efforts, resource management, and conservation.

Introduction

Rust fungi (Pucciniales, formerly Uredinales) represent the largest natural group of phytopathogens and can cause devastating diseases in agricultural, horticultural, and forest habitats, resulting in millions of dollars in damage annually (e.g., rusts of wheat, corn, coffee, and soybeans). There are also some species that have been used as biocontrol against weeds, such as Phragmidium violaceum (Vargas-Gaete et al. 2019) and Puccinia species (Tanner et al. 2015; Bean et al. 2024). They are obligate biotrophs of plants (Arthur 1934; Savile 1971), requiring a living host for development, and have complex life cycles that may require up to seven spore types produced in five different spore stages and alternation between two phylogenetically unrelated host plants to complete their life cycles (Aime et al. 2018). Rusts are distributed across all geographical areas on wild and cultivated plants. It is expected that infectious plant disease ranges will shift under climate change (Caubel et al. 2017; Dudney et al. 2021; Miller et al. 2022), and current lists of species diversity will allow the study of changes in their distribution. Our work seeks to document the current knowledge of rust species present in Indiana.

Rust collection in Indiana began almost 200 years ago. References date back to a specimen labelled Aecidium dircatatum (now known as A. hydnoideum) on Dirca palustris (Thymelaeaceae), collected by Lewis David von Schweinitz during a visit to Hope in 1831 (McCain and Hennen 1982), and records of a rust destroying the foliage of blackberries in Henry and Wayne counties in 1872–1874 (Furnas 1874). However, the first explicit report of a rust fungus in the state was made by John M. Coulter in 1876, who documented a rust on Lespedeza violacea (Fabaceae), presumably near Hanover (Jackson 1915; McCain and Hennen 1982). We must also acknowledge the work and legacy of Joseph Charles Arthur that made uredinology flourish in the state of Indiana. Arthur named 29 genera and 309 species of rust fungi from North America and influenced the work of uredinologists like Frank D. Kern and his successors as directors of the Arthur Fungarium (PUR), George B. Cummins and Joe F. Hennen (McCain and Hennen 1982). Indiana became a state strong in uredinology history, heavily influenced by the PUR, housed at Purdue University. This fungarium represents the major center in the United States for taxonomic studies of rust fungi (McCain and Hennen 1982; Kaishian et al. 2024).

The first account of the rusts of Indiana was presented at the annual meeting of the Indiana Academy of Science in 1890 by E. M. Fisher on the Parasitic Fungi of Indiana, with a considerable number of species mentioned; however, this work was never published (Jackson 1915). A list of those species was obtained by Dr. L. M. Underwood and was included in the first published compilation of Indiana rust fungi by Underwood (1893). It listed 88 rust species observed across 19 counties, with most observations reported from Montgomery, Putnam, Johnson, and Tippecanoe counties (Fig. 1A). Additional lists were later published, including a list of rusts of Tippecanoe County in 1896 by Lillian Snyder and supplemented in 1898 with lists from Madison and Noble counties, as well as lists for Hamilton and Marion counties by G. W. Wilson in 1905, and two complete state lists by J. C. Arthur (Jackson 1915). An updated list was published by Jackson (1915), reporting 141 rusts, 34 of which were new reports for Indiana. The number of rusts for Indiana was later updated to 155 (Jackson 1917) and 165 (Jackson 1920). Since the efforts by Jackson, various rusts and new host records have been reported as part of the sixth annual A. H. Smith Great Lakes Foray (Schoknecht 1981), as specimens evaluated in rust biogeography studies (McCain and Hennen 1981), and studies of rusts on Cyperaceae and Juncaceae in Indiana (McCain 1984). In recent years, efforts have been carried out to document all fungi in the state, including a checklist of Indiana microfungi (Bates et al. 2019). However, the taxonomy for Pucciniales in this list needs considerable revision. Despite the significant efforts to document rusts in Indiana from the past 100 years, a checklist of all Pucciniales in the state has not been compiled since the works of Jackson from 1917 to 1920. This study was undertaken to generate an updated list with a modern re-evaluation.

Scale bars represent number of specimens studied per Indiana county. Grey color represents no rust reported for that county. Tippecanoe County (filled in black in panel B) was not included in the scale bar representation in panel B for comparison purposes between the two studies, as it was disproportionately represented with 2605 specimens.

Checklists are vital sources of information that set a benchmark for decision-making in research efforts, resource management, and policy (Reyserhove et al. 2020). Checklists have been valuable in monitoring, modeling, and predicting species presence and distribution in diverse groups of organisms. These include pollinators (IPBES 2016), rare species (IUCN 2020), and invasive alien species (Seebens et al. 2017; Reyserhove et al. 2020). They are instrumental in studies related to biodiversity conservation initiatives (Lowman et al. 2018; Parker et al. 2018; Menchetti et al. 2021; Lacher et al. 2022), discovery of new species (Pierson et al. 2014; Cantonwine et al. 2019; Nicolai et al. 2020; Maharani et al. 2022), and changes in response to climate change (Pearman et al. 2024). Furthermore, the use of herbarium records is highly valuable in ecological and epidemiological studies and modeling, such as assisting with the listing of rare taxa (Molano-Flores et al. 2023), providing data for biodiversity and landscape monitoring (Çelekli and Zariç 2023, informing conservation biology (Greve et al. 2016), setting baseline data particularly for poorly inventoried regions (Greve et al. 2016; Park et al. 2022), and supporting the study of phenological (Jones and Daehler 2018; Williams et al. 2021) and global environmental changes (Heberling et al. 2019; Lang et al. 2019). Access to the Arthur Fungarium, in this study, presented a valuable opportunity to assess and document the presence of rusts across Indiana with the purpose of generating a curated dataset to inform future ecological, epidemiological, and conservation work. This project verified records for potential misidentifications, known synonymies, and use of incorrect or obsolete names to reflect the most current classification for these rusts and the report of new records for the state. We provide a complete, up-to-date record of the Pucciniales species and their hosts known from Indiana.

Methods

This checklist was compiled from a variety of sources, including published literature (e.g., Arthur 1934), online databases [MyCoPortal: https://mycoportal.org/portal/collections/list.php (MyCoPortal 2025 and the U.S. National Fungus Collections database: https://nt.ars-grin.gov/fungaldatabases/ (Farr and Rossman 2018) and unpublished herbarium records. Data for the Arthur Fungarium (PUR) are maintained in the open-source software “Specify 7” by the Specify Collections Consortium (https://specifysoftware.org). Sources for each listing are provided within the list. The authors of fungal names follow the conventions in Index Fungorum (http://www.indexfungorum.org/names/AuthorsOfFungalNames.asp), and the current name of host plants follows the conventions used by the PLANTS database (http://plants.usda.gov) and Plants of the World Online (http://www.plantsoftheworldonline.org/). Herbarium specimens were studied to confirm dubious names or records, as well as for species represented by only a single statewide report.

The checklist is arranged alphabetically by genus, species, and subspecies-level taxa. Each species/subspecies is annotated with host family, species, and source of record. The current names of rust species are printed in bold type. Names not printed in bold are synonyms or other non-current names. References were inserted following the host name. The checklist does not include species that were the result of inoculation studies in greenhouses and that are not naturally occurring in the area (i.e., Hemileia vastatrix—PUR66308 and Phakopsora zeae—PUR51735).

We generated a specimen number by county list using location information from verified vouchers in the Arthur Fungarium (Suppl. material 1). Other sources of observations were not included in this analysis, since the level of detail for location varied among specimens. Metadata for records originating from PUR accessions are available in Suppl. material 2.

Maps depicting the number of observations per Indiana county were generated using map charts in Microsoft Excel version 16.88 (Microsoft Corporation, 2024). Additionally, all taxon names on the checklist were cross-checked against MycoBank and Index Fungorum by running a search for each name. Search results accuracy was categorized based on whether the correct current name was present in the search results as the current name or listed as a synonym, if an older name or another name was referenced as the current name in the database, or if a search of the current name or old name returned no results. The results from these searches are available in Suppl. material 3.

Results and discussion

Our checklist of rust fungi in Indiana includes a total of 301 current names, 339 synonyms and non-current names, and 13 ambiguous names. It documents 301 Pucciniales taxa (275 species, 21 varieties, 4 subspecies, and 1 forma specialis) distributed on 900+ host taxa. Most of the specimens from Indiana housed in the Arthur Fungarium are from Tippecanoe County (57.6%), with 2,605 out of 4,516 specimens collected in the same county where the fungarium is located. The next most sampled counties show a markedly smaller percentage, with Jasper (2.45%; 111 specimens), Montgomery (2.24%; 101 specimens), Hamilton (1.97%; 89 specimens), Putnam (1.97%; 89 specimens), Franklin (1.77%; 80 specimens), Fayette (1.64%; 74 specimens), Lawrence (1.64%; 74 specimens), and Kosciusko (1.44%; 65 specimens) counties. A total of 28% of counties (19/90) have between 20 and 53 specimens vouchered in the PUR (from highest specimen number to lowest: Porter, Marion, LaGrange, Brown, St. Joseph, Steuben, White, Warren, LaPorte, Fountain, Spencer, Lake, Carroll, Madison, Vigo, Henry, Posey, Orange, Parke, Wayne, Noble, Warrick, Marshall, Crawford, and Johnson). While another 28% of counties (19/90) have between 10 and 19 specimens accessioned per county (from highest specimen number to lowest: Jefferson, Owen, Starke, Jackson, Newton, Martin, Washington, Gibson, Clark, Harrison, Perry, Pulaski, Clinton, Knox, Monroe, Benton, Cass, Fulton, and Vanderburgh), 41% of the Indiana counties represented in the PUR collection have less than 10 specimens vouchered in the PUR per county (Fig. 1B). A detailed list of all counties and their respective number of specimens in the PUR is provided in Suppl. material 2.

The recorded distribution of rust fungi in Indiana has been attributed to the distribution of the collectors and is likely representative of changes in land use (e.g., conversion to agricultural land in a large part of the state). McCain and Hennen (1981) pointed out that over 70% of Indiana rust fungi at the time occurred within easy collecting distance of West Lafayette, where the PUR is located (e.g., Fig. 1A). The distribution data was skewed away from eastern and southern Indiana, with information at the time only for 44 of the 92 Indiana counties, evidently exemplifying the distribution of collectors rather than of taxa (McCain 1984). Although this disproportionate representation from Tippecanoe County persists—an issue that continues to this day—the PUR currently houses specimens for 90/92 counties in Indiana, only lacking representatives from Hancock and Ohio counties. This highlights the advances in Pucciniales knowledge for Indiana in the past 40+ years and the efforts to conduct fieldwork across the state. Yet, it is still clear that systematic statewide specimen collection is lacking to generate valid biogeographical or phenological hypotheses (McCain 1984).

Our checklist includes a total of 339 Pucciniales taxon names that had been previously reported for Indiana that are currently obsolete names, as well as 13 ambiguous taxon names. Taxonomic confusion has characterized rust fungi due to the development of multiple classification schemes, homoplasy in diagnostic characters, and the use of separate naming systems for sexual and asexual morphs under prior nomenclatural codes. Additionally, more than 200 generic names have been described in Pucciniales, but only about one-third of those names are accepted (Aime and McTaggart 2021). Taxonomy and nomenclature of many of the rusts reported in Indiana have changed over time and not always kept up to date in records. This became evident in the rusts listed in the recent checklist of Indiana microfungi (Bates et al. 2019). This study provides updated names with the most correct identification based on a re-evaluation of the dataset considering current taxonomy.

Index Fungorum (https://www.indexfungorum.org/) and MycoBank (https://www.mycobank.org/) are regularly consulted by mycologists and plant pathologists to assign current taxonomy to their rust fungi samples. Nevertheless, we note that these public name repositories may still contain inaccurate names (Suppl. material 3). Both repositories seem to follow similar patterns of accuracy/inaccuracy (Fig. 2). Of the 653 names listed on our checklist (301 current names, 339 synonyms and non-current names, and 13 ambiguous names), only 58.5% (MycoBank) and 63% (Index Fungorum) of these names directly refer to the correct name when conducting a search in each database. The misidentifications and use of obsolete names are usually not congruent between the two databases. Discrepancy issues between these repositories are known and extend to disagreements in terms of placing genera to family- and order-level, based on differential updates and taxonomic opinion (Durkin et al. 2020). Our goal is that this resource, with the most up-to-date taxonomy, serves as a reference point for correct identification of rusts from Indiana to plant diagnosticians and researchers.

Search results accuracy was categorized based on whether the correct current name was present in the search results as the current name or listed as a synonym, if an older name or another name was referenced as the current name in the database, or if a search of the current name or old name returned no results.
