Abstract

During a survey of ophiostomatoid fungi in native forests of southern Argentina, several isolates of Huntiella species were obtained from Nothofagus trees. Sequences of multiple gene regions were used to identify these fungi, and their pathogenicity was tested on N. pumilio and N. dombeyi. Phylogenetic analyses revealed a novel taxon described here as H. decorticans sp. nov. Inoculations on N. dombeyi and N. pumilio in the forest showed that H. decorticans is able to produce localized lesions on healthy Nothofagus trees.
