Asco sur Inonotus dryadeus
Bernard CLESSE, 16-08-2017 19:20
Bernard CLESSEBonsoir à tous,

Hier j'ai trouvé, sur vieux polypore pourri (Inonotus dryadeus) au pied d'un chêne, cet ascomycète.

a) paraphyses hyalines, cylindriques, septées, à contenu réfringent

b) spores subfusiformes, arquées, remplies de guttules et triseptées à maturité : 18-24x5-6,5

c) asques IKI-, à crochet à la base

d) poils serrés, ± subulés, arrondis au sommet, à contenu réfringent

Une idée ?

Hi Bernard,

I think we are somewhere in the world of "bald" discos with strong IKI reaction in the paraphyses (the same VB visible in your photos turns amber). Phaeohelotium/Calycina/Trabinella - just shooting names (from Zotto's folders). Maybe Zotto has a good suggestion for this big-spored species. Maybe this one also falls into "Pezizellaceae", otherwise the big picture is still unclear here as far as I know...

Re : Asco sur Inonotus dryadeus
Hi Timo,

Thank you for your opinion ! 

I have done some photos of the asci that are well IKI + and not IKI- as I had previously reported. Apparently, the reaction does not come on.

I also observed the excipulum that seems typical. I see clavate cells.


Best regards,


Bernard
