that’s probably because a few of the Galerina are also thought to be moss parasites… as well as many other genera.

For whatever it’s worth, there’s same browning of moss in Observation 77028.

Tephrocybe and References

Tephrocybe is hard. This might turn out not to be one! (although I think it is). It’s mostly recognized in the field by exclusion of other taxa. Lots of them are moss parasites, so the fact that this seemed to be actively killing the haircap moss (?) around it was a good clue.

Clitocybe, Mycena, and especially the smaller Lyophyllum and Rhodocybe can be tough to separate, as well as things like Fayodia, Gamundia, Myxomphalia and that whole mess of genera.

As for references for AK – European resources can be helpful because many of the taxa encountered here appear to have circumboreal distributions. It is, after all, closer to Siberia than to California. Many eastern species are also present due to the abundance of host trees that are otherwise absent on the coast of the the lower pacific states (most notably Birch!).

There has also been a lot of effort to document the arctic and alpine mycoflora (there’s a whole journal about it for instance), so it has received more attention and work than many other western states.

Some questions:

1. How is Tephrocybe best distinguished in the field?

2. What’s your/Noah’s reference(s) for these Alaskan posts? Seeing some new names I’m not familiar with.
