Cercophora rubrotuberculata sp. nov., a new pyrenomycete from the Great Smoky Mountains National Park.

An interesting wood-inhabiting pyrenomycete was discovered while collecting for the All Taxa Biodiversity Inventory currently being conducted in the Great Smoky Mountains National Park. This species is unique in possessing superficial ascomata with reddish tubercles and ascospores that develop an apical swollen brown cell and a long, basal hyaline cell. Because these ascospore characters fit the traditional morphological circumscription of Cercophora, this species is described as a new species within this genus.
