Numbers 3 & 4 made my jaw drop so hard my wife asked what happened.

That "fractured glass" appearance is awesome(!), and 300 frames may be a new record.

This is very nice work, Paul!

Thanks! These were exciting to watch the stacks grow, I didn't know what I was looking at with the 'mushroom' and still don't, really. These things must have particularly large cells.

The first overview shot was just ambient room/window light (big soft box) pointing away from the window with the bellows shading direct window reflections, the next two were bent plastic diffuser dome with tissue and side light, the last, I had to crank up the ISO, couldn't get light on it, just a bent piece of paper for reflector.

By 'mushrom' do you mean the umbrella like structure. If so there are male and female sex organs located in seperate receptacles. Males are umbrella like and females are umbrella like with only the 'ribs"

The most common thallus liverwort is Marchantia polymorpha. A weedy species, imported all over the world and common in plant nursery pots.
