FUNGUS ONE

Autumn is the peak time for spotting different fungi.  The bits we see are the 'fruiting bodies' of the  unseen fungus organism, made up of white threads called hyphae in bundles called mycelium.

This one grows in and on dead willow wood and is called Daedaleopsis confragosa . . . 

. . . . .  OR in English, the false maze gill  because the underneath is a bit like the maze gill fungus with a maze of slotted pores underneath; OR the blushing bracket because the underside bruises red if you rub it.
