edit: it appears not. Dactylina arctica is hollow, for one, therefore lacking any context, much less pink context.

Some images of X. polymorpha look convincing:


but none of them show any trace of pink context. A very interesting find indeed.

For all my luck at finding rather small things in the forest, I’m not much good at re-finding them – even though I generally wander in but a few square miles of woods. (I’ve hinted for a good handheld GPS for Father’s Day…) I will try to re-find this little fellow again in a few weeks & post any positive results.

thanks guys.

I must have misspelled it on my original search…it is apparently also found thru the yahoo search engine, if you just spell it correctly.

As luck would have it, I have that Texas book in my library, but I have never laid eyes on such a strange little asco before!

I see where you are going with that chamber speculation, Ron, but surely someone would have mentioned such a critical and obvious detail as a pink context! Also, in all of the other photos that I could find (admittedly not that many) the top of the fruit body doesn’t appear smoothly rounded like this one.

See if you can go back later in the season, Jim, and see what your curiousity grows up to be! You can clearly see a layer of black tissue underneath the white covering…but a good name, IMO, still eludes us.

Underwoodia columnaris

is a kind of morel with a grooved and chambered fruitbody (reminds of the stem on Helvella lacunosa). Hard to find a picture, but here’s an old one:
Helvella columnaris is a synonym.

wild pink context…

and what in heavens name is an Underwoodiae columnaris? Nothing online or on IndexFungorum, that I could find…

if those are the beginning of chambers I’m seeing in the last photo.

Sorry, Danny, but microscopy is beyond my abilities. I think sticking just with Xylaria sp. is the safest course for now. Thanks.

that there are several hundreds of Xylaria species described, I’ll reduce my vote on polymorpha to “Promising” ;-)

Not to disagree necessarily with the proposed name, but this strikes me as sufficiently different form X. polymorpha to warrant a closer look. Any microscopy would be very valuable in getting to the utmost bottom of this ID.

Smooth & Waxy

Smooth and waxy is an excellent description. The “finger” had some degree of flexibility, but snapped quickly and fairly cleanly (as in photo 4).

This looks Xylariacious but in form only. I see no powdery canidia atop the fruit bodies and the entire thing appears to be smooth and glabrous, almost waxy. Can you do a cross section and post another photo?
