As with any comprehensive fungal guide…

there are likely going to be some questionable entries, as well as a few downright errors. IF is no exception. Makes sense to me that the myosotis entity should be placed somewhere other than Hypholoma.

Anyway, I believe my understanding of Galerina has been broadened. Previous to this post/discussion my concept of the moss-loving (eastern NA) Galerinas did not extend much beyond the very small types found where moss grows on the ground or on a log… not in a wet bog like in this case. Thanks Jacob, Alan, and Byrain.

They’re probably out of date

I doubt a species with non-purple/brown spores is Hypholoma, its been given 10 different names in 10 different genera over time, who knows what it will end up.

calls it Hypholoma myosotis.

At any rate, Pholiota, Hypholoma, Phaeonematoloma… it’s the same entity.

As for this obs, I just compared the spores with a collection of myosotis I had made. obs 111679 Although I don’t currently have a micrometer mounted onto the scope I’m using, the spores in the myosotis obs are clearly larger than the ones seen here. So I think this rules out myosotis for this obs (168161).

Print was definitely not purplish/dark brown. So this rules out the (other) bog-inhabiting Hypholomas.

That doesn’t make it sound like Hypholoma to me, your link calls it Pholiota… So I looked up the name and it seems the current name according to mycobank is Phaeonematoloma myosotis.

H. myosotis does not have purple-brown spores..

Phillips reports the color as “snuff brown.”

Bessette calls the color “dull rusty brown.”

I have noted a reddish rusty luster. See obs 111679

This obs seems to differ from 111679 in there being more brown overall. If you zoom in on the smaller mushroom (168161), it appears there is a whitish annular zone, which is a trait reported for H. myosotis.

What do you mean by rusty?

Galerina has what I would call rusty brown spores, Hypholoma should have more purple/brown spores.

does match Galerina. But the size of these moss-dwellers’ caps (local moss-Galerinas are tiny), the closely arranged marginal striations, and the shape of the spores (almond-shaped as opposed to elliptic) do not well support Galerina.

H. myosotis is a real oddball species. Probably on account of the rusty spore color and spore shape it had previously been placed in Pholiota.
