Mean WNS histologic severity scores of dead or moribund bats collected from BWM and GM. Scores are averaged across body surfaces examined (wing, ear/muzzle). Scores were graded as 0—no fungi suggestive of WNS, 1—superficial and limited but suspicious of early WNS with hyphae in keratin and randomly into epidermis, but not yet forming distinctive cupping or dense packets, 2—More extensive superficial infection with epidermal cupping packed with hyphae diagnostic of WNS, 3—More severe fungal infection with tissue invasion including epidermal cupping packed with hyphae diagnostic of WNS, 4—Severe infection with tissue and wing damage worse than 3.
