Presumably the fruiting bodies of a Slime Mould such as Trichiales. They were growing from a transparent slime that can be seen in the images. Thanks to Barbara for the initial sighting of this tiny clump which was hidden away in the leaf litter.
Perhaps Trichiales but I wonder if this is Leocarpus fragilis - which I see often enough. That species is dark spored, but yellow in the plasmodial stage, and not one of the Trichiales
Thanks for the comments and identification @Heinol If I come across something similar to this, would it be worth me obtaining a sample for you to review? Tim
@Timl it's not worth collecting at this stage. It's not yet mature and, if collected, it might still mature but it might also abort further development.
@timL it would be great if you could return and find the mature specimen as I'm wondering if it could be a species of Paradiachia, as these form in much the same manner and the clear plasmo is suggestive of this species, thanks, Teresa
Hi @Teresa I'll try and get back to that area next week and see if I can find the mature specimen. I'll get back to you and let you know one way or the other. Tim
Hi @Teresa Sorry, I wasn't able to find the specimen again. If I find something like this again, I'll make sure it's left in an easily identifiable location for later observation and not hidden away somewhere under the leaf litter. Tim
Thanks for trying @TimL, these critters are very difficult to find when mature as many of them change colour so dramatically; these may have changed to black with some iridescence, which make them even harder to find amongst the leaf litter. Never the less, it was a great find and your efforts are appreciated. T
