Erumpent on Phragmites australis
Juuso Äikäs, 06-06-2020 20:25
I know next to nothing about these kinds of fungi but the microscopy wasn't what I was expecting. I thought the spores might be long and filiform or maybe multicellular. But they are quite small, one-celled and the paraphyses are lanceolate and contain a large VB or something like that. Does anyone know what this is? 

Spore dimensions: 

(6.5) 6.6 - 7.2 (7.3) × 2.1 - 2.4 (2.5) µm
Q = (2.8) 3 - 3.2 (3.3) ; N = 8
Me = 6.9 × 2.2 µm ; Qe = 3.1

Re : Erumpent on Phragmites australis
I managed to find one rather promising candidate: Hysterostegiella valvata. 

http://www.centrodeestudiosmicologicosasturianos.org/?p=23617

In that source the substrate is apparently Ammophila arenaria, so Poaceae as well. Paraphyses look just right and spore size and appearance is also pretty much the same.

Re : Erumpent on Phragmites australis
I have to clarify that in the first pic I think at least a part of those are actually Lophodermiums or something like that. I re-examined the sample and they had filiform spores. Both species are growing on the same culm near eachother. Here's a pic that I think is of the possible H. valvata:
