This is a very very small mushroom, the cap is less than 1cm wide max. Though it should be easy to spot because it fruit in very large numbers on decaying conifer wood. Usually the wood is very old and degraded. It’s unlikely that you would be able to tell it’s conifer wood from looking at the wood itself. When I found the ones pictured below, I was in a mixed forest. So, it’s possible that these are actually Xeromphalina kaufmanii. However, both species fruit in warmer temperatures, have a yellow to orange “golden” cap. Gills that run slightly down the stem, are distantly spaced, and are cross-veined. The thin stem, especially at the base is often a darker reddish brown, and the spore print will be white.
