| 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. |
