What preys upon a jacaranda tree?

Fungi and salt prey upon jacaranda trees.

Specifically, the jacaranda tree (Jacaranda acutifolia, J. mimosifolia) generally can be counted upon to cause few problems in the private and public places in which it may be planted. It nevertheless is sensitive to certain fungi and to salt water. It may perish from the fungal disease known commonly as mushroom root rot and scientifically as Armillaria root disease. Without immediate attention to soil drainage and treatment schedules, the proliferation of mushrooms at the tree's base in summer and fall will bode poorly for jacaranda below-ground (and therefore also above-ground) body parts.
