I found these in a group growing in leaf litter to the left of the path.

They had large, white caps, with yellow-tinted apexes.

The large stems were also white, and there were globule-like pieces on the caps.

The gills were white, and wavy.

The next week on Day 5 (15 October 2022):

On Day 6 (23 October 2022), they were slightly more wrinkled and darker brown at the edges and apex.
