Similar to Pyronema?

Several fruiting bodies grew from a piece of stick lying on the burnout. Ascomata small, about 1-1.2 mm.
Spores slightly rough, no content. Non-amyloid ascus. Blue discoloration under the influence of Lugol occurs in the subhymenium area.
Are spores with ornamentation and a blue reaction typical of this genus?

Re : Similar to Pyronema?
Hello Mirek,
the asci are actually diffusely amyloid. I'd compare with a Iodophanus, probably I. carneus or I. testaceus. (They were synonymized some time ago, I don't know whether it was confirmed genetically.)
Cheers,
Viktorie

Re : Similar to Pyronema?
Hi Viktorie.
Thank you very much!
I had also met Pyronem in the same place before, so I was a bit confused. The microscopic structure is very similar, but a few differences were immediately visible during microscopy. Iodophanus so far I have not had the opportunity to meet, so I am very happy with this find and your suggestion.
I found a job on them, so I will read in the evening and if I can do it, I will take a few more micro photos.
I think I. testaceus is very likely.

Thank you once again and best regards.
