This strange growth on an alder cone is actually a fungus with the rather apt name of Alder Tongue (Taphrina alni). The fungus grows out of the ripening cones of alder trees, after the female flowers have been pollinated in the spring. Initially green in colour, it forms a gall that changes to orange and then dark brown as here. This particular example is from the Cynheidre Open Cast Site where alder trees abound. Once you get your eye in its amazing how many Alder Tongues you can come across.
