Daniel Winkler found something quite similar in Columbia. Webpage here:
http://mushroaming.com/...

He called it tentaculata as well, but I agree, neither yours nor his fits the gestalt of the well known SE species, altho when young those arms can be a good bit shorter and thicker.

See these two NA obsies here on MO:

and one with multiple heads:

Certainly possible that there are cryptic species. What does Roo have to say???

Thanks

for the information. Hopefully I will be able to see it mature and collect more data on it in the following weeks.

X. tentaculata consists of many thin, stromatal “arms” radiating out from a single axis to form a hemispheric “bouquet” of apices. The similar looking, highly branching Xylaria examples in the Neotropics I have seen have their branch tips emerge from more of a fan or paddle than a central point, and those branches follow the axis of that fan/paddle, rather than jutting out in all directions from same. Think of the head of dandelion covered in windblown seeds (X. tentaculata) vs. a cockscomb or a hand with fingers outstretched (others).

Definitely

multi headed with a single stem. Looks like tentaculata but when touched it emits asexual (white) spores, which means it is not ready for microscopy.

very cool Xylaria, Nicolle!

but what exactly is going on here? Are they all fruiting out of a single woody substrate? Is it a multi-headed fruit body?

it does resemble X. tentaculata, but who knows what it is, really?
