Ash, beech, elm, maple.
Other broadleaved species.
Found on old pruning wound sites and columns of dysfunction where bark has been lost. Usually in abundance.
Annual (rehydrates). Jelly-like / rubbery. Upper surface begins white and scurfy and develops zoned bands of greens, browns, and whites. Pore surface gelatinous beige-brown. Desiccates to a dark purple beneath. Unmistakeable.
Auricularia auricula-judae (in early stage – skin-coloured).
Attributed to a white rot of the wood. No research has been undertaken on the pathogenicity of this fungus. Isolated usually to dysfunctional areas. Presence of pruning wounds suggests decay behind the stub. Abundance longitudinally indicative of a decay column.
