Plectania seaveri (Ascomycota, Pezizales), a new discomycete from Bermuda

Plectania seaveri sp. nov. is described after revision of Bermudian material identified by Seaver under the name Bulgaria melastoma. The only known host for this new species is the endemic Bermudian tree Juniperus bermudiana (Bermuda cedar), a species whose numbers have greatly reduced over the past 70 years due to the introduction of invasive scale insects. As this new fungus has not been collected since 1940, it may now be extinct. Color pictures of fresh and dried specimens, microscopic morphology, and a black and white drawing of hymenial elements are included. Related, excluded, and doubtful species of Plectania are also discussed.
