Time lapse: Arcyria affinis

On 30 September 2017 a patch of newly forming white sporangia caught my eye so I set up the camera on tripod in order to photograph the maturing fruiting bodies. By the following day the white had turned a pale pink characteristic of a developing Arcyria sp. By 9 October its capillitium had lost its shape and fallen away from the calyculus, a characteristic of A. affinis. (A. denudata, which is much less common at Black Sugarloaf than A. affinis is scarlet or carmine red when it first appears and its capillitium retains its shape and remains attached to the calyculus.)
