Hysterobrevium on Phragmites

Enrique Rubio, 26-11-2019 19:23

This Hysterial grew on stems of Phragmites australis lying on the ground in a very humid place. The micro and macroscopic features lead me to Hysterobrevium smilacis, a fungus that I had always seen growing on a variety of dry substrates but never on wet places.
What do you think?

Re : Hysterobrevium on Phragmites

Hi Enrique,
What I see in your photos completely agrees with what I'm used to observe in H. smilacis. Here are some links of my observations:

https://mushroomobserver.org/269814?q=12frf
I always observed this species in more or less dried places.
Best regards,
zaca

Re : Hysterobrevium on Phragmites

I was really surprised to see it in such a humid place. I've always seen it in dry or very dry places.

Re : Hysterobrevium on Phragmites

Maybe the stem was upright when the fungus developed and broke down when it was already mature? I think the wetness of the soil has little influence on drought-tolerant ascos above.

Re : Hysterobrevium on Phragmites

It's possible that what you're saying happened, I don't know.
