title: A new species of Rhytisma causes tar spot on Comarostaphylis arbutoides (Ericaceae) in Panama.
abstract: A fungus causing tar spots on leaves of Comarostaphylis arbutoides (Ericaceae) in Panama is described as a new species, Rhytisma panamense. The fungus forms gregarious black stromata on pale yellow spots on the adaxial side of leaves. Its ascomata develop from unilocular or multilocular stromata. An analysis of a combined dataset of DNA sequences from LSU to ITS rDNA supports the placement of the species in the genus Rhytisma.
