Tympanis on Pinus

The primary spores appear to be first clavate inside the asci, then develop several septa, and finally split into thousands of secondary spores.
Could this perhaps be Tympanis confusa, or is it even possible to tell the species?

Re : Tympanis on Pinus
Hola Juuso.
Algo muy parecido a lo que nos muestras y sobre el mismo sustrato lo mandé a secuenciar y el resultado fue que se trataba de Tympanis pini NR_173027

Saludos.

Re : Tympanis on Pinus
Thanks for the suggestion Josep.
My finding didn't have those large globose spores, so I think this might be something different.
I found the paper Reassessment of Tympanis based on types of ascospore germination
within asci, and Tympanis confusa is the only species that fits from the ones included in it.
I did a few measurements and got 27.7 - 31.4 × 4.1 - 5.2 µm for the clavate/septate spores, 2.9 - 3.3 × 1.0 - 1.2 µm for the tiny ones and 93.4 - 96.1 × 16.5 - 22.4 µm for the asci.
The spores and asci are a bit wider than in the paper, but otherwise everything would seem to fit T. confusa. The study is half a century old though, so I don't know how relevant it is these days...

Re : Tympanis on Pinus
Hi Juuso, T. confusa is probably the only Tympanis growing on wood. Look here for more recent info https://doi.org/10.11646/phytotaxa.411.3.2

Re : Tympanis on Pinus
Thank you for the comment Adam. The only Tympanis growing on wood sounds interesting, but unfortunately I don't have access to the article.

Re : Tympanis on Pinus
Sci-Hub should have the article
