Bonsoir.Voici un Rutstroemia trouvé sur branches de Bouleau au sol dans une tourbière.
Ce qui m'étonne, c'est la forme des spores, cylindriques quasiment jamais incurvées comme je pensais les trouver, peut-être à tort d'ailleurs.
La clé que j'ai m'amène à R. firma mais sans conviction toujours à cause de ces spores que je pensais incurvées chez cette espèce.
Micro :
Asques IKI+ bb, 140-160X8-12 um, boucles présentes.
Spores bisériées, cylindriques, 16,9-19,8X5,6-6,5 um avec deux guttules, Q=2,8-3,3
Paraphyses filiformes à apex arrondi, septées, larges de 2-3 um.
Qu'en pensez-vous ?
Merci par avance.

Hi Yannick
I know this straight-spored form and never understood if it is the same as the perhaps more often seen curved-spored R. firma. But I saw both forms on Quercus, see DVD, e.g.,Rutstroemia firma cf., 22.9.79.JPG and HB 5372.
Your twigs, are they really Betula? Did you look on the wood whether it is not ring-pored? On your photo I think this could be Quercus.

Re:Rutstroemia
Hi Zotto.
Twigs are certainly Betula. There were just Betula and Picea all around this peat bog. But I will see that.
Thank's a lot.
