to get back up in the mountains by April, I will definitely collect specimens for shipping if I find anything remotely like this.

These must be immature because they do not show the perithecia.
Here is a mature specimen of Poronia:

an image hoster and a link is the only way I know of. I don’t think we can embed images.

looks like you got it!
Here is one from FL (on shroomery, cow pattie hunters…)

amazing that this is in the Xylariacea!

Wish that you took a photo of the undersurface of its cap, but it does appear to be a Poronia, one of the stipitate members of that group that grow on dung. Here are details for this genus from an online Xylariacea key to genera:

for ranjini, nor can I say whether we collected the same thing (although judging by the similarities and the corresponding locations, I think it’s safe to assume they are at least close relatives), but the specimens I collected had pores on the underside of the caps.

The species illustrated by Guzman
By: Christian (Christian Schwarz)

has a very long, dark stipe, with no swollen fertile surface like the common ones shown when you do a google search.

Here’s the ones I found:

sadly I didn’t take more pictures. I have specimens in Atlanta but am currently in Kerala.

the Pore make that specimen extremely interesting, nice find!

Though the stipe
By: Milo (Mycophiliac)

looks like a Sclerotinia, everything I’m reading on the genus makes them seem like plant pathogens which aren’t mushroomlike at all. I’ve found these as well and they are not cup fungi – they have pores on the undersides of convex caps.

Also, they were growing on dung [when I found them, at least].

I unfortunately didn’t take enough pictures to be of much use to identify them, but if I see them again I will.

It was found growing on elephant dung. Thanks for the id!

growing on dung? Were the stems hard and bulbous towards the bottom? Were the caps gilled or pored?
