A new species of the genus Alternaria, A. humuli-scandens, on Humulus scandens is reported. A. humuli-scandens is the first large-spored Alternaria species with long filiform rostra reported on plants of Cannabaceae. A. humuli-scandens is different from all the known species in the genus Alternaria based on the morphology and pathogenicity.
