help with this ID. It was especially difficult, I believe, because the specimen was a found in very wet conditions. In spite of that, you were able to help me zero in on what I am confident is now the correct ID. Your comments and suggestions were invaluable, and your willingness to share your expertise is much appreciated.

Thanks, Dave. That info gives me …

another avenue to research.

Except for the pale color and grooved margin…

I think C. erebia may apply here. (What I have IDed as such is lighter and without marginal striations.) Accounts of this mushroom are generally found under the name “Agrocybe erebia.” Reported as viscid when wet. A few online photos labeled “erebia” show grooved margin. According to IndexFungorm, the current genus for erebia is Cyclocybe. A late season type.

It might even be an Armillaria, for all that I can tell. The extremely wet condition and ambiguous gill photo make it a hard call. It’s definitely not a Gymnopus though.

Rocky, thanks for the suggestion.

I looked through all the MO observations for A. praecox group and checked some additional references. From the observations, it looks as if pretty much “anything goes” with this group. I think I may even have seen a Tubaria in there. My specimen is not what I would call a robust mushroom; cap definitely has striate margin; gills are mottled. Also the fruiting was in mid-October as opposed to Spring. Considering all that….?

You are right about that, Matt.

I didn’t notice that one on the leaf until I downloaded my pictures. Wish I had noticed it at the time. Fungi are everywhere when you develop your eye for them. What do you mean by a “snotty” mushroom? It was a bit viscid, but it was soggy in the woods that day.

if that’s the case…

better watch out for the yellow patches on the leaves in the third picture.

Oh and I wanted to post Limacella but I saw the gills in the 4th picture didn’t quite match up. Was it a snotty fungus?

You like that, Matt?

Those birds nests are a dime a dozen in that particular area. Couldn’t crop it out without loosing too much of the photo. I thought someone would probably want to call it a mixed collection=)

Nice bird’s nest fungus in the background
