Trichopeziza cf. sulphurea - but with (too?) small spores
Lothar Krieglsteiner, 09-01-2021 16:42
Lothar Krieglsteiner.. collected 8.6.20, Germany, Bavaria, Neuburg a.d. Donau, "Kreut", on Mentha longifolia. 
I think almost everything fits with T. sulphurea (that grows (only?) on Urtica), including the hemiamyloid pore, with the exception of the small spores - I measured them 23-33/+-3 µm.
Is this too small or can it still be accepted for sulphurea?
Best regards, Lothar

Hi Lothar

in my foles this is the perfect spores size of sulphurea = nylanderi: I have in my folder name 18-39 x 2,5-3,5(-4).

The asci are withou croziers?

I had the spacies once on Impatiens gland. and Francois valade on Phytolacca.

Zotto

thank you, Zotto!
I have looked in an older key of yours, where the measures are larger.
I must more look in your folders, in future ...
So everything is o.k.
Best regards, Lothar
P.S. I fear I did not look for the croziers ...

I can't find larger measurements, only the width may go to *3-3.8(-4).

But you are right, my old key says 33-38/2,5-3,5 µm, so neglects shorter spores.
