*MSUMC, Morehead State University Museum Collection; Oo, Ophidiomyces ophidiicola; UWZM, University of Wisconsin Zoology Museum. †Samples are listed as positive if >1 PCR assay targeting the internal transcribed spacer region or mitochondrial NADH dehydrogenase subunit 1 gene was positive. See Appendix 1 for assay-specific results. ‡Based on Baker et al. (5). §Equivocal indicates some histologic features consistent with ophidiomycosis were present but >1 diagnostic features were not observed (Appendix 1)[[ANCHOR###T1######Anchor]].
