Pas d'idée.

It looks like a Dendrostilbella

Thank you very much Ethan !

Do you know if it is Dendrostilbella smaragdina or if there are several neighboring species ?

Kind regards,

Bernard

From what I have seen on other forums, it certainly seems plausible that this is D. smaragdina, but I really am not an expert in this genus.

Hello Bernard,

In February 2019 I got a look-a-like from Jan-Henk.

A Dutch website gave me a direction to get an answer: Studies in Mycology no. 27.


Easiest choice for me: "conidiomata" - "pigmentation of stipe": green: 10, 26, 43

3 species left:
10. Stilbella flavipes p. 68
26. Tubercularia smaragdina p. 127 = Dendrostilbella smaragdina
43. Dendrostilbella prasinula. Teleomorph: Claussenomyces prasinulus p. 182


Tubercularia smaragdina/Dendrostilbella smaragdina:
"Tubercularia smaragdina is an unusual species recognized by its green synnemata which turn darker green in KOH and bright blue-green in lactic acid, the presence of a lime-green subiculum around the bases of the synnemata, and the acropleurogenous phialides. Because of the unusual coloration and KOH reaction, it is unlikely to be confused with other species of Tubercularia. The other green synnematous fungi with phialides, Dendrostilbella prasinula and Stilbella flavipes, lack acropleurogenous phialides"


But that doesn't fit for what I saw ....

Acropleurogenous = Conidia developing at the tip and along the sides of the conidiophore.
