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

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

Re : Pyreno with strange spores
Hello Maren,
Would you please be so kind as to explain how you add such neat scale bars to your photomicrographs
Kind regards

Re : Pyreno with strange spores
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
