Another fungus on Tilia wood

Hello again and happy new year for allTogether with the ascomata of Psilocistella/Psilachnum species on Tilia wood that turns reddish with ammonia vapour (see the macrophoto) they were another witish cupulate ascomata with big 8-spored asci IKI (-) negative and croziers (+) positive. IKI with KOH pret. is negative (-) too.
The marginal hairs are very agglutinated and very difficult to segregate. Initially they seem to be smooth but the end cell is very finelly verrucose in KOH. For it, my impression is that this fungus could be a Cistella species that I don't know.
What do you think?
Many thanks again

Re : Another fungus on Tilia wood
I once had a Cistella on Tilia bark of an attached branch, together with a strange and new Orbilia (O. jurana) on the calcareous Schwäbische Alb. It has also inamyloid asci but spores much smaller (7-12 x 2-2.8), so I identified it as Cistella cf. mali. Yours has too large spores for mali.
One with such large spores on Populus bark (HB 6930) has faintly hemiamyloid apical rings.

Bonjour Enrique,
voir peut-être du côté de "Cistella" perparvula mais tes spécimens présentent des spores et des asques plus grands.
Amitiés, Guy
