Re : Vibrisseaceae(?) sur phragmites
This looks much like Belonopsis guestphalica ?= B. iridis.
I thought this is a Dennisiodiscus but the only sequence so far places it in Mollisia, although it has no VBs. Therefore we are searching for a second sample for sequencing. How abundant is yours?
The species is highly problematic because it varies strongly in spore size. Perhaps different species are hidden behind it. I made a table of about 20 samples, showing spores from *(22)25-35/2.4-2.6 up to *50-65 × 2.3-2.6, mostly 3-septate, rarely up to 5.
You could look if there is an outer layer on the ectal excipulum that reacts bluish in iodine, this was often the case.
For photos see my folder in Dennisiodiscus (under Pyrenopezizaceae).

Re : Vibrisseaceae(?) sur phragmites
Many thanks Zotto.
This fits indeed very well with the foto's in your folder.
I still have three very tiny samples.
Should I keep them for sequencing? If so I'll not try the iodine reaction on the ectal excipulum.
Kind regards.
Camille

Re : Vibrisseaceae(?) sur phragmites
You mean 3 apothecia. Perhaps we can wait, Torsten Richter is searching for the species as well. If he does not succeed, we can come back to you. In the meantime I want to ask for the collection data. The stem was surely lying in the mud, or was it standing and the apos at the water level?

Re : Vibrisseaceae(?) sur phragmites
I should of course said apothecia.
The reed came from a pond, immersed, lying down and half-buried in the mud.
The ectal excipulum turns indeed blueish in iodine.
