Calycina heterospora et autre
Yanick BOULANGER, 17-02-2025 21:29
Bonsoir
Pour le premier, il s'agit de Calycina heterospora déjà identifié sur ce forum il y a peu de temps.
Pour le second, cercle rouge photo 4, je ne vois pas ce que c'est
J'imagine qu'en grande quantité comme c'est le cas, c'est peut être des conidies
Il n'y a pas d'asques
Si vous avez une idée ?

Re : Calycina heterospora et autre
It is so that a very recent ITS sequence of a C. heterospora collection by Torsten Richter (Brandenburg, on Salix) fully coincides with Cylindrocephalum kendrickii. That anamorph has 1-septate cylindrical conidia formed in brown phialides with a long-cylindrical neck. The photos in the protologue (Wu et al. 2023) are made in dead state.

But your anamorph seems to be something else, with 3-septate conidia formed in ?hyaline phialides.

Re : Calycina heterospora et autre
Merci pour la réponse et le document
Oui mon anamorphe est autre chose qui restera surement non identifié

"It is so that a very recent ITS sequence of a C. heterospora collection by Torsten Richter (Brandenburg, on Salix) fully coincides with Cylindrocephalum kendrickii." 

So, this taxon could be combined in Calycina and C. heterospora would get a valid name with Calycina kendrickii. I just looked up - Calycina is somewhat older than Cylindrocephalum.

Re : Calycina heterospora et autre
Yes, but the problem is that Cylindrocephalum forms a clade separate from the core of Calycina, at least with rDNA analysis. But C. citrina clusters even more remotely. So everything depends on which concept should be applied. Also we do not know the genetic variation of this species. Perhaps Cylindrocephalum zhejiangense is too similar to be treated as a distinct species.
