An unusual soft-rot decay pattern caused by the Ascomycete Hypoxylon mediterraneum (de Not.) J Miller

IRG/WP 1222

D M Francis, L E Leightley

A distinct pattern of soft-rot decay has been observed for the fungus Hypoxylan mediterraneum (de Not.) J. Miller. This fungus also produced decay patterns typical of brown and white rot decay. The production of characteristic cavities by Hypoxylan mediterraneum was prolific in the hardwoods Eucalyptus maculata and Eucalyptus regnans, but infrequent in the softwoods, Pinus elliottii and Pinus radiata. The chemistry of this decay was investigated using carbon-13 nuclear magnetic resonance (13C-NMR). This technique produced results valuable to the understanding of the timber decay activities of Hypoxylan mediterraneum.
