We used herbarium specimens of Silene virginica, S. caroliniana, S. rotundifolia, and S. latifolia to survey the incidence of anther-
smut disease (caused by Microbotryum violaceum sensu lato) in the eastern USA. We found no evidence of a collector bias against
diseased specimens. Diseased specimens were frequently found in collections of S. virginica and S. caroliniana, but not in those of
S. rotundifolia or S. latifolia. Disease incidence in S. virginica and S. caroliniana increased significantly over the past century and
was higher in marginal populations. The absence of disease in specimens of S. rotundifolia is consistent with field observations, but
