Hi Jackie, its quite common at this time of the year, on all sorts of poop, but it is very small, about 1 – 3 mm. tall I think this is Pilobolus crystalinus, species to be clarified by the herbarium, and I have now found 4 species over the years on possum, macropod, wombat and rabbit. Because its difficult to see in the field, I often bring the poop home and see what I can grow in moist chambers. LOL, pots of poop everywhere......
