sulphur fungus (sulphur polypore) The common name for the fruit bodies of Laetiporus sulphureus, which are bracket like, typically growing in tiers. The upper surface is irregular, suede-like, and initially a bright sulphur-yellow or orange-yellow, later fading to a dull whitish colour. The tubes on the underside are sulphur-yellow with small, more or less circular pores. The spore print is white. They are found on various broad-leaved (living or dead) trees, particularly oak.
