Occasionally associated with Cylindrocladium floridanum and Cylindrocarpon tenue on rotting roots of unthrifty tea bushes in Mauritius. Associated with a root disease of dying 10-15 year old trees of Araucaria angustifolia (Hodges &amp; May, 1972). Roots of such trees are pitch-soaked and copiously exude resin, causing large quantities of soil to stick to the roots, thus resembling in symptomatology the brown root rot caused by Phellinus noxius. Also isolated from the roots of dying trees of several species of Pinus (Hodges &amp; May, 1972). The pine needles on affected trees turn bright yellow, droop, and finally turn brick red. Roots were pitch-soaked but resin exudation was slight. Also isolated from seedlings of Eucalyptus saligna (Hodges &amp; May, 1972).
