Importance and distribution

Two species of Arnaudiella, A. caronae and A. eucalyptorum have been transferred to Pycnoseynesia and Phaeothyriolum, respectively. Arnaudiella comprises ten species known on a wide range of host such as Belairia spinosa (Papilionaceae), Bupleurum fruticescens (Apiaceae), Cytisus scoparius (Fabaceae), Empetrum nigrum (Ericaceae), Eucalyptus sp. (Myrtaceae), Fitzroya cupressoides (Cupressaceae), Genista horrida (Fabaceae), Lobelia stricta (Campanulaceae), Panicum antidotale (Poaceae), Podocarpus uviferum (Cupressaceae), Polystachya sp.
