Who: Bob Zuberbuhler (Bob Z)

No specimen available

Found in profusion on the trunk of a living black walnut tree. Small, ill defined white thalli with interspersed, variable size brown cups with white borders; some much larger than the thalli. In other areas the thalli are larger, lobed and better defined, but no cups seen in those areas. May be different species?
