Pathogenicity of Botryosphaeria dothidea (=B. ribis) to giant sequoia (Sequoiadendron giganteum) and coast redwood (Sequoia sempervirens) was demonstrated in greenhouse inoculations of both hosts and in field inoculations of giant sequoia. Both the teleomorph and anamorph were found on giant sequoia, and their identity was confirmed by single-ascospore isolations and inoculations. No evidence for host specificity was found.
