Philippe PELLICIERBonjour, pensez-vous que S. ceijpii soit le nom co
Found on rotten wood of unknown species. Just 0.4mm across on what appeared to be a very short pedicel. Pale yellow with a hint of green (not as green as the image would suggest). Only one apothecium found which is immature.
Asci weakly amyloid in Lugol's, no obvious bluing at the apices: 97-108 x 10-12 µm
Most asci too imature to show spores clearly. The image shown would appear to have muriform spores.
Paraphyses longer than the asci, multi-septate and constricted at the septa.
Not expecting much from this but it might remind members of a genus.
Regards, Chris
I believe your sample is a Claussenomyces species or at least related, the blue reaction of the wall it is not clear to me, maybe an artifact, and as far as I know only Claussenomyces pseudosugae have blue reaction in the asci wall, but it is clear and strong. There are too many similar species in the genus, I have worked several types species, but I have some more to review and right now I cannot give you a identification with the data that you show. It is important you see the ascoconidia, secondary ascospores that form conidia balls inside the asci when they are living. If you collect again other sample try to photograph a general section of excipulum, more ascospores and the ascoconidia, then maybe we can try to fit at species level.
best wishes,
Luis
Many thanks for looking at this for me. Claussenomyces looks very convincing and I'm more than happy to have a genus at this stage. With just one immature apothecium, it was never going to be conclusive.
The fragment of wood I have hasn't produced any more apothecia but I will revisit the area later this month.
I have noted you comments on what to look for.
Best regards,
Chris
