Cath, I was so intrigued when you posted this sighting on Monday that I detoured via that site on my walk home that afternoon. I'd assumed this was an ascomycete and one I hadn't seen before so I was keen to get a herbarium collection. I've put up a brief note at https://admin-canberra.naturemapr.org/Community/Species/Sightings/45292. There are a couple of features I want to recheck in fresh material so I'll be going back there.
