Very nice to see this. The second record for the ACT - and a long way from the other location.

how exciting !
Can you explain what the structure are ?
and why this photo looks so very different from the other record (I would have thought completely different species)

Here (https://www.anbg.gov.au/bryophyte/photos-captions/plagiochasma-rupestre-03.html) you see another colony of this liverwort. Along the long central axis of each strap-like thallus you can see a few larger, whitish dots. These are clusters of protective scales over the areas that will develop into female or male receptacles - sperm being produced within the male and eggs within the female. Here (https://www.anbg.gov.au/bryophyte/photos-captions/plagiochasma-rupestre-01.html) is a closer view of one thallus and here (https://www.anbg.gov.au/bryophyte/photos-captions/plagiochasma-rupestre-02.html) you can see some slightly raised and knobbly receptacles. Once fertilized the eggs will develop into spore capsules, the capsules held within complex structures. In your sighting the large and brighter green spore capsule structures are already well on the way - not the case in the other sighting.
