The pixie's parasol (Mycena interrupta) is a small detritivorous mushroom with a Gondwanan distribution pattern, being found in Australia, New Zealand, New Caledonia and Chile. It grows up to about 2 cm (1 in) in height, with the blue cap also growing up to 2 cm in diameter. It appears in small colonies on rotting, moist wood in rainforests and beech or eucalypt forests.Photo: JJ Harrison
