Mollisia retincola
Juuso Äikäs, 20-05-2020 16:05
A while ago I said that I'll stay away from Mollisia but I guess I have to take my words back. 
I was reading Fungi of Temperate Europe and the title's species struck me as quite distinctive and something that might be possible to identify. (Belonopsis retincola is apparently a synonym and Species Fungorum claims that Trichobelonium kneiffii is the current name.)

So I visited a small pond nearby that has Phragmites australis growing in it. I found these almost immediately, growing on dead, standing culms near the waterline.

This time I managed to get a clear yellow KOH reaction. The medulla has plentiful crystals in it and the spores measure 23.4 - 26 × 2.8 - 3.4 µm. 

With the combination of these characteristics, I'm quite confident this is indeed M. retincola.

Re : Mollisia retincola
Hi

IMHO, you marked well.
In my microscopic collections, the spore length range was more diverse. Maybe you only measured the longer ones?
To be sure, I would check croziers.

Re : Mollisia retincola
There weren't that many spores and I measured only five so that would probably explain it.

Re : Mollisia retincola
This is a very common species on Phragmites australis. You will definitely meet him many more times.
Not all features are always compatible (variability?).
