Also called ‘Sulphur Shelf’, this is a bright yellowy-orange bracket fungus which is usually found on the trunks of standing trees. They are irregularly shaped or fan-shaped, overlapping one another, and have a lumpy texture, somewhat akin to cooked chicken. The pores are white or a pale yellow. Underneath the bracket there are tiny round or oval tubes. Fruit body 10 to 40cm across, 3 to 12cm thick.
It can be seen all year round. Usually found on deciduous trees, mainly oak, and rarely coniferous trees, although its seems to have a preference for Yew (Taxus baccata), which can be quite a pest. Widespread and common.
