Extensive group of 1.2 mm high stalked sporangia with globose to hemispherical sporotheca, 0.4 mm diameter with an iridescent peridium.
Capillitium of yellow nodes connected by colourless threads. Spores are brown in mass, paler by transmitted light, minutely punctate with groups of darker warts, 8 microns.

Extensive group of stalked sporangia 1.2-1.5 mm high. Iridescent peridium; yellow nodes of calcium carbonate within the spore mass; spores brown in mass, lighter brown in transmitted light, minutely punctate with groups of darker warts, 8 microns
Found on decaying log of Exocarpus cupressformis in wet eucalypt forest.
This species regularly appears on this log, usually after rain in summer or early autumn.

This specimen was collected by Rebecca (Becky) Lash who reports "I was looking at all the beroe when a blob that I thought was a dead mnemiopsis started flapping its little flappers. Don’t know what it’s been eating but it’s digestive tract seems full" It was brought to the MBL where we placed it into a tank to take photos. I recognized it as a pteropod and did a GBIF search for the group. None of the species seemed to fit. I posted on the Falmouth Wildlife Facebook group and a member referenced an article on "Sea Angels" I looked up the source and found a reference to Cliopsis krohnii, the only member of this genus. Looks much more of a match than Clione limacina. Going with that. Have video.

This little snail had a shell no wider than the length of a sugar ant, so maybe only a few millimeters. Its body was a translucent grey. The shell had rough growth rings and on the back whorl was not closed entirely.

I photographed this life form recently, and was intrigued by this particular frame. It reminds me of any number of things, but is hard to pin down, so I am making it into one of my infrequent quiz photos. After any interested friends have responded, I will upload other photos that will make the ID clear.
Edit-1. I ran it through the AI suggestions, and it is flummoxed--interesting!
Edit-2. See comments. This is a Lion's Mane mushroom, Hericium erinaceus. I have reordered the photos to show the widest shot first.
