Flames without fire …
In Britain, the Flame Shield, Pluteus aurantiorugosus is an uncommon find and is primarily restricted to southern England and south Wales. It occurs mainly on rotting broadleaf stumps and large logs of buried hardwood timber. The specimens depicted were found and photographed in a hollow cavity within a heavily decayed beech in West Sussex; the cap of the single specimen about the size of a small pea. This strikingly beautiful species can appear at any time from early summer right through to the end of autumn providing the weather is mild.
