HI again
I need your help again with these isolated or caespitose perithecia up to 0.5 mm, situated on erumpent stromata, with mammate dark ostiole, KOH purple only in the upper region.
Ascospores broadly fusiform, 1-septate, not constricted at the septum, smooth. Asci with truncate apex and a refringent conspicuous apical apparatus.
Close to the perithecia we can observe fascicles of witish erect conidiophores that could be the conidial state of this fungus (cylindrocarpon?). Could be a Thelonectria species?
Thanks again
il devrait s'agir de Thelonectria discophora, mais il faudrait vérifier si les spores sont lisses ou spinuleuses,(sur tes images elles m'apparaissent spinuleuses).
Amitiés,
Christian
Bonsoir Christian
J'ai fait plusiers preparations des espores mais je n'ai vu pas acune ornamentation sur les memmes, ni avec l'aide du bleu cotton. Il est possible que les espores de T. discophora etaient lisses?
Une autre question: les conidiophores et conidies que j'ai vu peut il s'agir de l'anamaorphe (Cylindrocarpon) du Thelonectria discophora?
Merci
