“…inundata is widespread in the south coast and some wheatbelt regions and has been associated with dying native vegetation including the grass tree (Xanthorrhoea preissii) in several southwest locations of WA (Stukely et al 2007). Additionally, P. inundata has also been associated with dying horticultural shrubs and trees including Aesculus, Olea, Salix, Prunus and Vitis (Brasier et al 2003b;Cunnington et al 2006).…”

During one spring season, 12 Phytophthora species, two Phytophthora hybrids, three Halophytophthora species and three Phytopythium species, were isolated from 48 waterways across Western Australia. The waterways were sampled using nylon mesh bags containing leaf baits of up to six different plant species and were isolated by plating necrotic lesions on these onto Phytophthora-selective agar media. Phytophthora species were isolated from all except one waterway. Of the Phytophthora species isolated, eight are known while the remaining four are undescribed taxa. Six of the Phytophthora species and the two hybrids are from clade 6. The two hybrids and P. inundata were the predominant species recovered.Recoveries from different plant leaf baits varied with the best two baits being Pittosporum undulatum and Banksia attentuata; and from these two combined all Phytophthora species were isolated. There was a marked difference in the Phytophthora diversity in the waterways from different regions. This is the first comprehensive study from Australia to examine the Phytophthora communities in waterways, and advances our understanding of the role of these oomycetes in natural and anthropized ecosystems.

“…and undescribed Phytophthora taxa (Stukely et al 1997, 2007a, Stukely et al b, Burgess et al 2009). The recovery of Phytophthora taxa other than P. cinnamomi from some sites with declining vegetation in WA has recently focussed attention onto their role in the decline of these woodland and forest ecosystems (Shearer & Smith 2000).…”

A new Phytophthora species, isolated from rhizosphere soil of declining or dead trees of Eucalyptus gomphocephala, E. marginata, Agonis flexuosa, and another 13 plant species, and from fine roots of E. marginata and collar lesions of Banksia attenuata in Western Australia, is described as Phytophthora multivora sp. nov. It is homothallic and produces semipapillate sporangia, smooth-walled oogonia containing thick-walled oospores, and paragynous antheridia. Although morphologically similar to P. citricola, phylogenetic analyses of the ITS and cox1 gene regions demonstrate that P. multivora is unique. Phytophthora multivora is pathogenic to bark and cambium of E. gomphocephala and E. marginata and is believed to be involved in the decline syndrome of both eucalypt species within the tuart woodland in south-west Western Australia.

“…It has been recorded from host genera Salix, Olea, Prunus and Vitis in Europe and South America (Brasier et al, 2003), and more recently from soil around carrot and parsley crops in Victoria (Cunnington et al, 2006), soil, dying and dead native vegetation in WA (Stukely et al, 2007), and it was the most commonly isolated Phytophthora species from streams and waterways baited throughout Perth and the South-west of WA (Huberli et al, 2013). Like P. inundata, P. litoralis is also most commonly found in water-logged areas, and has been recovered from dying Banksia species in native ecosystems and from streams .…”
