Tiny stalks tapering and lighter coloured towards the top with cracking yellow spherical eggs for heads. About 3mm tall and 0.4mm wide at the heads. Growing from under a wet eucalyptus log. When the heads dropped away the brown spore mass dissipated almost immediately leaving just a hair-like stalk.
This tiny wasp is Chalcididae spp., identification confirmed by Ken Walker. It was recovered from a bucket of water and thought to be dead. It revived while being looked at under the microscope! Guess the warmth of the light aided recovery.
Patches of lemon yellow tissue about 1-2mm thick, on bare, dead, barkless nothofagus trunk. Tiny dark spots (ostioles) from which ascospores are released.
In a tall rain forest national park.
This was previously called H sulphurea, the northern hemisphere version but recent work has proven it to be a different species. A wood-rotting ascomycete, which might also colonize some other fungi.
Good views of one at rest and ? another in flight. This year in Bayside I've made my latest May record, my only July record (28th) and some "possibles" in the last week or so. My earliest August record before this was on 23.8.12. Climate variability?
