Observation 113991: Ascomycota Caval.-Sm.

Is this a pin lichen, or a fungi?

On the lower surface of branches and on protected areas of bole of Geoffoea decorticans.

Thallus: salmon pink pin top. stalk black, but on the lower photograph, the stalks look much lighter color – are these the same ones?

find this again and rephotograph it with a tripod, using the lowest end of the working distance spectrum (ie: get as close to it as you can). the surface ornamentation of the “ball” and a look at what’s inside it will almost certainly tell us more.

If a lichen, not really any primary thallus

In the top two photos of the underside of the branch, I can kind of see some spotted green areas on the branch that look like maybe it could be a primary thallus…

But in additional photos I just posted of collections from the upper surface of the branch, there´s no green thallus… the upper and lower surface might still be different species, so I´ll collect from the underside of the branch today, but I´m getting pretty positive that they are the same folks, and its a fungi… or if a lichen, it is not a Caliciod — that the samples from the upper surface have dried showing total mushroom like heads…

I could be convinced it’s a lichen

My gut tells me it’s not. Only pink-ball-on-a-peg lichens I know are in Baeomyces and Dibaeis, and both of those have obvious crusts with algae in it. This thing has no crust at all as far as I can tell. It could be a calicioid, as Nastassja suggests, but I don’t know of any with big pink balls like this. (And a few look kind of shiny, but I can’t say for sure.) But I’m hardly an expert on Argentine lichens!!

versed is going a little far. i’d defer to you, damon, long before I’d call myself an authority on the things. my vote was on account of the “ball on a peg” look they’ve got… nothing more.

I think this is a lichen. However Danny who’s versed in slimes say myxo and Jason who’s an expert on lichens says its a fungi. It just doesn’t look like a mxyo for me. Would have to be a Physarum if so, and I have not seen any as such…

Yes, same tree, different parts though…

I only know Calicium viride and another one that I don’t the name of… so I have little experience with Calliciodes…

I agree, it looks fungal.. but the ones popping out the bottom of the branch (top 2 photos) look so different than those hanging out on top (3rd photo). The ones hanging from the bottom of the branch have so much more the silhouette form of a pin lichen, while the ones in the 3rd photo have more of that characteristic fungal stumpy stalk. But the pin heads on both look very very similar…

It’s so hard to see these things in photos

Could be different things in top and bottom photos. Were they all on the same log / tree? Just doesn’t look like a calicioid to me.

Yes… totally agree…

But the lower photo and the top two photos, they have different color and quality stalks… could the two top ones that are protected from direct water runoff be pin lichen and the photo on the bottom be fungi?

Or is that pink head on those top two photographs just too not-pin lichen like? Its definitely not mazaedia thats for sure…

I’m thinking unlichenized fungus…

Look far too large and colorful for a calicioid lichen (also would never grow on the upper surface of anything in a place that rains so much). Doesn’t look like a slime mold, either, too scattered.
