Hi everybody,this pyreno with strange spores is a find from last weekend on Urtica dioica.
Perithecia 0,3 mm, immersed, Spores hyaline, irregular 2-septate, the smaller part seems to break away, (22-31) 27,16 x 5,46 (4,5-7) µm, Asci 90-93x8 µm, IKL blue, long apical apparatus with 4 µm.
Thanks
Maren

Re : Pyreno with strange spores
Hi Maren,
It reminds me Anthostomella rubicola, spore shape and size fit quite well, be it usually grow on Rubus.
Best regards,
Daniel

Hi Maren,
most likely an Anthostomella. I never encountered this genus on Urtica. Sure it was not Rubus or something similar?
Cheers,
Jacques

Hello Maren,
Would you please be so kind as to explain how you add such neat scale bars to your photomicrographs
Kind regards

Hi Maren,
this one looks quite like Anthostomella. There is a chance to send me the material, always ;)

Re : Pyreno with strange spores
Thanks to you all :). Of course the substrate is Rubus, I mixed it up, sorry.
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
