has close brown gills and according to M. Kuo : “This small, dark brown saprobe appears in northern and montane areas of North America, and can be recognized quickly if a drop of KOH or ammonia is applied to its cap, producing a green color change. But without the chemical test . . . well, you’re looking at a little brown mushroom with a white spore print and no distinctive odor or taste. In short, you may need to unpack your microscope.”

Brown spores on Phaeocollybia rule it out.

Gill color, thickness and placement rule out Gymnopus. Laccaria makes the most sense; according to M. Kuo: " There is evidence that at least some species of Laccaria may serve as pioneers in disturbed ground or de-forested areas that have recently begun the long road of ecological succession that leads, eventually, to a “mature” ecosystem. Thus, for example, several species of Laccaria are frequently found in young pine plantations." See: Kuo, M. (2010, December). The genus Laccaria.

The other observations on MO have a very pruinose stem & thin gills while this obs has a smooth stem & thick gills.

as shown on MO has gray or gray-brown gills. This obs. has orange or lilac-orange gills. Also the gill pattern is not the same. Gymnopus villosipes has straight gills, this obs. has branched gills.

As do gymnopus.

This was reported as white spored here.


Maybe no trees,

but seedlings? Laccaria are among the most common mycorrhizal fungi around, and are especially common in nurseries.

BTW, the lines visible in the cap are called “striations.”

No trees, they were growing in a clear cut, near a culvert by the side of the road, they were found growing out of woody debris.

trees in vicinity?
