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
