Pyronemataceae but which Genus?
Pauline. Penna, 25-11-2023 15:37
These 3mm yellow turbinate discs were found on top of a very rotten stump, in compost not on the wood, which  maybe coniferous. Upper surface smooth, soft tissue, underside whiteish, powdery.

Asci J-ve operculate 260 x 15 microns, eight spored. Spores 13-17 x 8-9 microns, thick walled, smooth with granular content. Paraphyses not branching, some with curved and swollen tips, greenish in MLZ.

Keying it out I get to Otidea or Octospora. Help please, it does not seem to fit in these genera

Re : Pyronemataceae but which Genus?
Hello, 

somehow it reminds me on Pseudoboubovia benkertii, but I have never seen it myself.

Best wishes,
Viktorie

Yes, it seems the correct ID

Re : Pyronemataceae but which Genus?
Thanks so  much Viktorie and Nicolas. I have just looked at Paul Cannons site on Fungi of Great Britain and Ireland and it confirms your suggestion. So  it was in Pezizales after all.
Many thanks
Pauline

Re : Pyronemataceae but which Genus?
Hi Pauline, 

Yes, this is the species that I had by my Cupressus hedge (see the Feb. 2023 edition of Field Mycology). I assume that the ascospores were full of guttules, not easy to see in your photos. In my specimens the paraphyses were partially obscured by an amorphous matter. Interesting that this asco has turned up in another oceanic location in the UK. 

Best wishes, 

Charles.

Re : Pyronemataceae but which Genus?
Hello Charles I will have to look at FM to see your report.. The spores in the asci were full of guttules. I was concerned because I thought the paraphyses were greenish in MLZ. It looks a very good match in all other respects. When was it first described, it  is not in any of my books?
What a great resource Ascofrance is, I think I would have been struggling on for sometime.
Best wishes Pauline

Re : Pyronemataceae but which Genus?
Hi Pauline, 

Yes, I got the ID through AscoFrance-very helpful. There's loads of info on it online and there's also some background info re taxonomy in my article. It has been quite frequent by my Cupressus hedge under the clippings. Wonder if it's there now?!

Charles.
