Hi Maren,
It reminds me Anthostomella rubicola, spore shape and size fit quite well, be it usually grow on Rubus.
Best regards,
Daniel
most likely an Anthostomella. I never encountered this genus on Urtica. Sure it was not Rubus or something similar?
Cheers,
Jacques
Would you please be so kind as to explain how you add such neat scale bars to your photomicrographs
Kind regards
Peter
this one looks quite like Anthostomella. There is a chance to send me the material, always ;)
regards,
björn
I Had difficulties with the keys because the fungus doesn't have brown spores yet. I got apparently rather young specimens.
@Peter: It's a rather simple method, first I took a picture of an Objekträger (I don't know the english word) with measuring scale (1000x), so I got the scale bar. I add this to my picture which also is taken with 1000x magnification with a image editing program.
Regards,
Maren
