I found these in clusters in grass along a path.

They fibrous clay-buff stems and orange-brown caps which faded to cinnamon at the edge.

They were found in clusters of two or three, or on their own.

Day 4 (08 October 2022):

By path side in long-ish grass.

Less than 20mm across, the caps were grooved orange-brown with a white edge.

The stems were less than 1mm, and orange-brown.
