Viscid on hardwood

This was growing on a fallen willow, and the cap was slightly viscid.

Some random musings of Galerina sect. Naucoriopis

The interesting paper from Gro Gulden et al. did show (suggest?) that most of the species in the Autumnalis and Marginata stirps of sect. Naucoriopis in the Smith and Singer monograph of North American species of Galerina, were in fact all the same species, and that the preferred name is G. marginata.

In further publications of G. Gulden, it was mentioned that this is probably a complex here, and that more work should be done to further understand things.

In making these all one species, it kinda ignores the fact that there are consistent recognizable differences here. The main difference is in the viscidity of the pileus, where G. autumnalis is, and G. marginata isn’t. This is a simple verifiable way of telling one from the other, although I’ve found some dry lookin’ G. autumnalis that being viscid was hard to tell, except as the gelatinized layer under the scope. (And in other news, I’ve yet to find a verified G. marginata sensu stricto from California, if you have one, please send it along…)

So, me myself, since there are recognizable difference in forms here, and a suggestion that they are the same species, I would like to list them as G. marginata forma something-or-other, to keep the obs separate and gain more knowledge on where and when one form appears from another. Listing them all as G. marginata kinda sweeps the differences under the rug and looses the ability to gain a bit more knowledge here.

This isn’t really up to me, although… so I’m not sure what others might want to do here. There really are three main forms that are easy to tell in the complex, two on wood – G. autumnalis is viscid, G. marginata is not, and one on the ground – G. unicolor is sometimes viscid or not. (Although I found G. autumnalis on the ground near a well rotted log, I was assuming there was enough woody material in the soil.)

So, just to perhaps gain more knowledge, I’ve been keeping the obs. separate in my notes. And someday I hope to be able to use G. marginata f. autumnalis for an obs. like this one. (I assume this one was viscid?)

(Oh, just to point out something, I saw a claim that G. autumnalis was on hardwood, and G. marginata was on conifer, and would nice to see that better verified or not (I for one find it hard to believe, but hey could be true…). And calling then all G. marginata would just erase a claim like this.)

Isn’t G. autumnalis now being called G. marginata?
MO still has both as valid… It is a nice photo.

Gorgeous photo, Dan!
