Daldinia sp?

[KeenTeen17]

Is this daldinia concentrica?


I know the purplish colour on the second one hints at auricularia auricula-judae, but it wasn't jelly ear because the log wasn't elder and it was quite a solid thing (not flimsy like jelly ear)

Texture of the first reminds me of Xylaria but obviously not.

I don't think I'll be alone in suggesting Exidia glandulosa- the felted black surface being key.

[leifus]

having looked it up I also think its Exidia glandulosa

old specimen?

[NickCantle]

I wouldn't say it's that old- generally a quite rough looking species in my experience.

one shouldn't really be confusing Daldinia (*- see below) with Exidia or Auricularia ; (NB auricula-judae occurs on a wide range of hosts - not just Elder)

* that said, the old idea that if it was of a reasonable size a Daldinia was concentrica and that if it was a smaller one and on burnt twigs/branches (especially Gorse) it was D. vernicosa is, sadly, out of the window: there are seven Daldinias on the GB list and the name vernicosa has disappeared . . . I look forward (when I've got hold of the literature) to getting to grips with the genus

PS - I shall post something Quite Interesting about Exidia glandulosa in a while . . . .

to tell whether it is D.concentrica you can cut it in half. On the cross section there will be 'consentric rings'.....

We all have to start somewhere mate, and in my early days I made many a diagnosis that was ridiculously off the mark. I say my early days, I still do it now! In this case, aesthetically, it does look similar with that odd hue. I think it all comes down to field experience and experience with handling and examining things you find.
