Philippe PELLICIERBonjour, pensez-vous que S. ceijpii soit le nom co
Coussin blanc, tanslucide, diametre max 1,5mm
Asques jusqu'à 170X15 µ, avec crochet, J+, 4 spores
Spores extrèmement variables de dimensions et formes (longueur de 20 à 50µ !), parfais à extrémité arrondie, parfois pointue
Paraphyses filiformes, avac vacuoles
L'aspect macro ressemble à Discinella shimperi, qui vient aussi sur sphagnum,mais la micro ne correspond pas,
Votre aide sera la bienvenue
Belle trouvaille, mais j'ai l'impression qu 'il y a un problème de maturité des spores.
Hymenoscyphus vasaensis est sur la même niche. Elle a des spores ressemblant à la forme de celles de ta récolte , du moins pour certaines. Et l'espèce (mais je ne l'ai vue que très peu souvent) à des asques à 8 spores
Amitiés Michel
Je n'ai pas de documentation sur cet hymenoscyphus. Tu peux me dire où en trouver?
Amitiés
This is a nice find. The presence of dense guttules / VB-like structures in the paraphyses here indicates it is not very close to D. schimperi / Helotium vasaense, which are probably sister taxa. However, I have only examined one (fresh) collection each of these so my experience is limited, but I observed paraphyses lacking this type of guttulation.
Perhaps Bryoscyphus s.l. is closer. 4-spored asci are unusual but there are some collections of undescribed species in Zotto's folder that are 4-spored: "B. tetrasporus" nom. prov.
The Helotiales on bryophytes are a difficult group morphologically. Do you think it will be possible to sequence this collection? Were there many apothecia?
All the best,
George
Effectively Zotto's folder 'Brioscyphus tetrasporus' seems to fit quite well with my finding.
I have kept few apothecia in the fridge. They are available for a sequence if you wish. As long as you tell me where and how to send them.
