Umbagong Fungi Project. Heino Lepp suggested these were possibly Collybia s.l. Several clumps found on a moist, shaded slope. The last 2 images are of a single specimen found several metres downslope from the others. It has different colouring - e.g., note the brown stem - could it be a different species? The latter was found at approximately Lat: -35.2147472; Long: 149.0241723. Many that appear to be the same / similar species were found at Lat: -35.216423; Long: 149.020959.
