Fusicolla?

Interesting species on the stem of Ruscus aculeatus (Serbia).
The closest is the genus Fusicolla, if I'm not mistaken. It is somewhat similar to F.ossicola or F.melogrammae but the substrate is different.
Ascomata perithecial, superficial, solitary or in groups, 200–220 um diam, not changing color in KOH. Anamorph not seen, but I found only one Fusarium-like conidia (?).

Re : Fusicolla?
Compare with Geejayessia ruscicola.
See:
Lechat C. & Fournier J. 2021. Geejayessia ruscicola (Hypocreales, Nectriaceae), a new species on Ruscus aculeatus. Ascomycete.org 13(4): 157-160. DOI: 10.25664/ART-0331

Re : Fusicolla?
Hi Nicolas, G.ruscicola is different. By the way, it is very common in my area, it is easy to find, the first time I found it several years ago, Lechat told me that he was preparing a paper about it. I saw them now as well, but on a different branch.

Re : Fusicolla?
Hi Savic,
I'm sure you are right with Fusicolla sp., but I cannot name the species - No collections are known from Ruscus as far as I know....
I found Fussicola ascomata on various substrates in the past (they seem to like it when other other Nectriaceae are present), but often I could not name them, even when I had a good quality ITS sequence.
I guess the situation might be similar to Fusarium species with gibberella-like anamorphs, in that there could be more cryptic species in a wide range of ecological niches (and with overlapping teleomorph morphology) than have been described so far. There are also several species that are only known from their asexual states.
Sorry, I haven't been much help :(
Cheers,
Nick
