Asco imparfait sur souche pourrie de frêne (Fraxinus excelsior)
Bernard CLESSE, 15-02-2020 14:37
Bernard CLESSEBonjour à toutes et tous,

Hier, j'ai trouvé cet asco imparfait sur souche complètement pourrie de frêne (Fraxinus excelsior).

Auriez-vous une idée ?

Bernard

Hi Bernard,

In the last 3 years I could make some finds, which I have collected in this forum.
https://www.pilzforum.eu/board/thread/39409-basidiopycnides-sp-sammlung/
Keith Seifert wrote me at that time about this genus that it is unclear how many species it contains, because the cultivation is so difficult.
I had given a few collections to cultivate, but unfortunately every attempt failed.
I noticed that this fungus loves wet substrate and likes to grow in combination with algae.

best regards,
Thorben

Hello Thorben,

Big thank you for your message! The microscopy and the macroscopy correspond completely to the photos that I saw on the following web link: https://www.pilzforum.eu/board/thread/39409-basidiopycnides-sp-sammlung/


Hello Josep,


Also big thank you for your opinion on my harvest and for the remarkable shared document: https://www.studiesinmycology.org/sim/Sim27/fulltext/index.html

Best regards to both of you )
