evolutionary reality

Have there been whole genome comparisons? Evolutionary reality is usually pretty messy due to genealogical discordance.This paper from 2015 mentions comparison of only a few genes, and it reports different species determinations from different models using the same data.


There are two species.

X. enigmatica is more closely related to X. kauffmanii than to X. campanella.

Species are defined by evolutionary reality, not by whether you can tell them apart.

one species

is my perspective if DNA & mating studies are needed and everything else matches.
But then I am a field guy.

X. campanella indistinguishable from X. enigmatica without mating studies or DNA

Xeromphalina campanella can be distinguished from X. enigmatica only by mating studies or DNA sequencing. They’re effectively identical in macroscopic features, microscopic features, chemical features, geographic location, and substrate preference.

The stipes look soft though don’t they.

Were the stipes hard, or soft?

They look like Hygrocybes, with the thick gills, except those wouldn’t be on wood, or usually gregarious like that. On wood it could be Xeromphalina, but that should have a darker, fairly stiff stipe, and more decurrent gills. There is also Chrysomphalina aurantiaca which will grow gregarious on wood, and has soft wide spaced gills, orange colors, this one is usually soft all over, with a soft light colored stipe.

On Wood?
By: Douglas Smith (douglas)

Was this on wood, or on the ground? If it was on wood, how bad was the wood, really, really rotten and half buried in ground, or a reasonably solid log?
