Pilobolus sp.
These truly tiny fungi form heads like glass spheres on a stem topped with a black spot. Their presence might be detected initially by feeling small wet specs on bare skin like tiny rain. A single body is about 0.3 mm tall.
In a local state park eucalyptus forest. These appeared all over some herbivore dung (almost certain to be kangaroo).
The head of this structure includes a clear glass-like ball which uses sunlight to ‘focus’ on as it grows. When internal pressure is sufficient the black spore mass, or sporangiophore, is shot out at a fantastic speed. It is one of the fastest actions known in nature. The spores are shot up to 3 metres away from the source and are spread over surrounding vegetation to be consumed by another herbivore.
