G. autumnalis or thereabouts.

Most Galerina photos on the Net are unreliable or straight BS. But this one does look as G. autumnalis, or let’s use the more precise method used by Doug below.

Galerina sec. Naucoriopsis

Just to make this a little more scientific-y, is seems that as far as it is known, the “deadly Galerinas” are all from the section Naucoriopsis of the genus. So you can say these might be different species of Galerina section Naucoriopsis, instead of the “deadly Galerinas”, just to be more accurate.

Same species?

I just posted another photo that shows these specimens growing on the same log with the more common form. As far as I’m concerned, they are all deadly Galerinas, different species of deadly Galerina maybe.

These same specimens are probably still out there. I will collect them tomorrow, along with a few other forms, and send them to Douglas. I’m betting they all turn out the same.

Pretty much agree plane to obtuse umbo.

Looking at descriptions of G. autumnalis and G. marginata:

“Le Genre Galerina”, Kuhner (1935) :
G. marginata – souvent convexe a convexe plan, obtus ou obtusement mamelonne.

Smith and Singer (1964) :
G. autumnalis – convex, then plane or with slightly obtuse umbo.

Watling and Gregory (1994) :
G. autumnalis – convex then plano-convex, often with low obtuse umbo.

Gro Gulden (2007) :
G. marginata – generally hemispherical …, rarely conical, expanding convex or
slightly depressed, rarely umbonate.

And I’ve only seen it with a low obtuse umbo, mostly plane to depressed. There is G. badipes with a nice conical peaked umbo, but that one I’ve only seen on the ground with the combination of moss and grass.

Not that this means anything… but looking over the photos on the ’shroomery, there is certainly some there that are not G. autumnalis, like the most conical peaked one.

It might be good to document the umbonate character or lack of character of G. autumnalis. If you want, you can send me along some dried samples of some umbonate and not.

but how did you determine that it was autumnalis vs some other galerina?

I could find no species description that included that narrow nipple; the best I could come up with was a “broad umbo.”

Yep, autumnalis.

The nippled form is rare, but I have photographed them before. Here is a link to a number of different deadly galerina forms I photographed a couple years ago. You can see some more that look like tits in the first post of this thread:


sure that this is autumnalis?

the nipple-headed cap is unusual…

Great shot showing the gills in situ!
