Back in October, I posted about two species of fungi colonising human-built structures, Jelly ear growing on the painted sides of a PortaCabin and an unidentified wood-loving species sprouting from the boardwalk railing at Cardiff Bay Wetlands Reserve (Fungi fight back, 27 October 2023).

During one of my circuits of Cardiff Bay in December, I found another example of fungi fighting back, these lush Oyster mushrooms on a finger post alongside the path to the Bay Barrage.
