Rutstroemia henningsiana?
Marc Detollenaere, 22-09-2023 18:10
Marc DetollenaereDear Forum,

On black remains, probably stromatized tissue, of Juncus effusus, I found some long-stalked apothecia of 5-6mm long.The ectal excipulum consisted of Text prismatica, asci had an amyloid ring, no croziers were found.Spores were hyaline, fusiform and measured 17-18x4µ and contained several large guttules (OCI 4-5).Paraphyses were cylindrical.No sclerotia were found.
Could this be R henningsiana?

Re : Rutstroemia henningsiana?
Macro, spores, paraphyses content don't look like in R. henningsiana; more like Hymenoscyphus.

Re : Rutstroemia henningsiana?
Yes, and it looks like Hymenoscyphus macroguttatus. That species must have croziers.

Re : Rutstroemia henningsiana?
... and by the way: the substrate is not Juncus but a dicotylous plant.
Yours, Lothar

Re : Rutstroemia henningsiana?
You are right Hans-Otto,

There are croziers but they are very hard to find

Re : Rutstroemia henningsiana?
Lothar,

I found it in a field full of Juncus effusus but indeed, the onset of side branches does not fit with Juncus.It has to be be a dicotyle.
