Hello everyone,a few days ago I collected this strange but beautiful fungi on a decaying, slightly moist fallen branch of Carpinus betulus in a mixed forest. No clue, what it could be ... possibly some Xylariaceae?
Locality: Slovakia, Súlov-Hradná, NNR Súlovské skaly
Habitat: mixed forest (nature reserve) - Carpinus betulus, Quercus sp., Tilia sp., Pinus sylvestris, Picea abies, Taxus baccata
Substrate: a fallen, slightly moist branch of Carpinus betulus (approx. 3–4 cm thick)
Perithecia: 250–400 µm
Spores: 7.5–9.7 × 2.6–2.9 µm, turning greenish-blue in 3% KOH
Asci: 8-spored, IKI– in both Melzer's and Lugol's reagents, in Baral's reagent finely blueish
Thanks for any suggestions!
Filip

Re : Xylariaceae? on Carpinus betulus wood
Hi Filip,
you should first make sure that what you call perithecia are not ostioles in relation with immersed perithecia. Take a razor blade and make a nice vertical section along the grain of the wood.
Cheers

And after that, could you check (it's not always easy) whether your spores have an apical pore? I get the feeling I've come across an undescribed species that turns up from time to time in my part of the country.
Have a good evening, both of you.

Re : Xylariaceae? on Carpinus betulus wood
Good evening both,
thank you very much for your replies.
Let me also apologise for the poorly done work I did.
I will do my best tomorrow and will keep you posted.
