Novel species of fungi described in the present study include the following from Malaysia: Castanediella eucalypti from Eucalyptus pellita, Codinaea acacia from Acacia mangium, Emarcea eucalyptigena from Eucalyptus brassiana, Myrtapenidiella eucalyptorum from Eucalyptus pellita, Pilidiella eucalyptigena from Eucalyptus brassiana and Strelitziana malaysiana(More)
The fine roots and ectomycorrhizae system of 18 declining Eucalyptus gomphocephala trees, in the Yalgorup region, approximately 100 km south of Perth, Western Australia, were exposed using an air spade and the relationships between the crown health and the fine root and ectomycorrhizal total density scores (TDS) were determined. Crown health was(More)
Tree declines are increasingly being reported around the world. Since the 1990’s Eucalyptus gomphocephala (tuart) has suffered a significant decline in the Yalgorup region, approximately 100 km south of Perth Western Australia. The complexity of many tree declines makes diagnosis difficult. Robust tools are needed to help identify factors contributing to(More)
Corymbia calophylla is an important eucalypt species endemic to the south-west of Western Australia. It is currently in decline across its native habitat for unknown reasons but perhaps due to climate change or to the presence of a recently described canker disease caused by Quambalaria coyrecup. Few fungal leaf pathogens have been described from C.(More)
Systemic treatment of stems with injections of phosphite liquid and novel soluble capsule implants of phosphite, PHOSCAP® (phosphorous, potassium, iron, manganese, zinc, boron, copper, magnesium and molybdenum) and MEDICAP MD® (nitrogen, phosphorous, potassium, iron, manganese, and zinc), were applied to Banksia grandis and Eucalyptus marginata trees to(More)
The health of Eucalyptus gomphocephala is declining within its natural range in south-western Australia. In a pilot study to assess whether changes in mycorrhizal fungi and soil chemistry might be associated with E. gomphocephala decline, we set up a containerized bioassay experiment with E. gomphocephala as the trap plant using intact soil cores collected(More)
