Abstract

A fungus parasitic on a fern, Dennstaedtia wilfordii (Dennstaedtiaceae), was found at the foothill of Mt. Fuji, Yamanashi Prefecture, Japan. Its hyphae spread within host mesophyll cells and through intercellular spaces, forming coiled haustoria in the epidermal and mesophyll cells. The hyphae emerged either through stomata or by disrupting epidermal cell junctions. The hyphae spreading over the abaxial leaf surface generated one-septate, thin-walled basidia. All the morphological features observed were characteristic of the genus Herpobasidium. The species identification of the fungus as H. filicinum by morphology was supported by molecular phylogenetic analyses of the D1/D2 region of the large subunit rRNA gene.
