Gooseberry tinder bracket, spindle bracket.
Hawthorn (potentially P. crataegi), spindle.
Other broadleaved genera.
Growing out on the root plate (including soil) through in to the crown of the host tree.
Perennial. Tough and woody. Usually in abundance and sometimes in tiers – remaining often individually small to more infrequently moderate in size (takes some years). Can have a bracket form or a resupinate form. Variable colours. Young growth (i.e. fresh) often a golden whitish to yellow-orange with a pinkish tinge – look on the underside if in bracket form. Mature growth darker golden- to tan-brown. Often mossy on the upper surface the bracket – generally also algal-stained (dark green).
Scant research has been done on its pathogenicity and little research has been done more broadly, due to rarity and genotypic variation between European genotypes and Asian ones. Usually signifies local dysfunction or systemic physiological decline. May be latently present (endophytic), due to its ability to colonise vast areas on declining and dead trees. Potential to therefore be a weak parasite. May cause failure local to the colonisation.
