Haradamyces foliicola anam. gen. et sp. nov., a cause of zonate leaf blight disease in Cornus florida in Japan.
A fungus causing zonate leaf blight diseases in various evergreen and deciduous woody plant species in Japan was characterized by a discoid multicellular propagule arising from a hyaline sclerotium-like structure in the leaf tissue and dark-coloured microconidia produced enteroblastically from the terminal cells on the surface of the discoid propagules. Myrioconium-like microconidiophores also producing microconidia were occasionally produced in culture. No teleomorphic characteristics were observed on the fungus. Molecular analysis based on the partial nu-rDNA sequence data revealed that the fungus was phylogenetically related to the Sclerotiniaceae, Leotiomycetes, and Ascomycota. Because the morphology and sequence data of this fungus does not coincide with those of any known anamorphic fungi, Haradamyces foliicola is proposed here as a new anamorphic genus and species for this fungus.
