xylaria cinerea?

Hi all, 

Unfortunately, I cannot provide more info than this image but could this be a Xylaria cinerea? 
Subtrate is hard wood, burried in soil.
in tropical forest of French Guiana


Thank you!

Re : xylaria cinerea?
Hi Dora,
a nice Xylaria indeed.
Unlikely X. cinerea which is temperate species, more acutely ended and with a different coating. Identifying a Xylaria in FG is challenging because of the huge number of species, half of them undescribed.
If you wish to make some progress in this genus, don't rely on macrophotos only but make detailed description sheets, details are essential and require thorough observations.
Good luck,
Jacques

Re : xylaria cinerea?
Thank you Jacques! It is really helpful to be reminded of this and at least exclude cinerea :)

I do imagine that these images are not sufficient with many of the species and at this moment I am still trying to orientate myself in between genera...The success of that at least have been confirmed :)

And yes, the problems with so many undiscribed species.

Thanks again and have a nice day.

Re : xylaria cinerea?
Jacques, would you send me an example of a detailed description sheet? just to get more familiar what to look at. 
Thanks!!
