Other deciduous broadleaved species.
Found along the stem and scaffold structure of the host tree.
Perennial. Usually resupinate. Generally, a darkish tan brown and sometimes with a greenish-beige to white outer perimeter. Very small fruiting bodies may be very difficult to identify. Where cankers exist on the host tree, a climbing inspection may yield identification results, though otherwise the presence of a canker may indicate its presence.
None, however cankers caused by Inonotus hispidus and Neofusicoccum parvum can potentially look similar.
Understood to begin by causing longitudinal canker damage along the stem and scaffold structure of the host tree, following which an intense (simultaneous) white rot of the heartwood and sapwood develops. When identified, it may be necessary for hollowness / residual wood strength investigations to be undertaken, in cases where targets exist. Because this fungus has been seldom recorded in England, the exact impact it has upon its host is not fully appreciated, though current cases suggest it could be a strong pathogen.
