Three species of Hypocrella with large stromata pathogenic on scale insects

摘要

Three species of Hypocrella characterized by large stromata and living on scale insects are described or redescribed. Two rarely reported species, H. gaertneriana and H schizostachyi, are associated with bamboo scale insects and are redescribed from South America and Thailand, respectively. The new species H. africana is described from scale insects on wood in Africa. A hyphomycetous anamorph with enteroblastic conidiogenous cells and two different conidial morphologies developed in cultures derived from Thai material of H. schizostachyi. These records and observations are put in the context of currently accepted Hypocrella taxonomy. [References: 15]
