Diaporthale on Geranium
Enrique Rubio, 08-06-2018 18:33
Enrique RubioHi to everyone
This enigmatic diaporthale makes subepidermial, roundish, blackish, up to 250 microns in diam., perithecia with central short beak on overwintered stems of Geranium pratense at the sea level.
Thes short stipitate asci have a conspicuous refractive melzer negative apical apparatus and the non septate ascospores have polar roundish caps at the poles, only visible with chlorazol blak.
I explored keys on Gnomonia-like fungi with no success.Have you some idea for me?
Many thanks in advanceEnrique

Hi Enrique,


This amazing fungus is probably new.

Hi Alain
Could you suggest me a genus?

Re : Diaporthale on Geranium
First, I tought in Apiognomonia, by the spore morphology, but any septa I have seen. Maybe Gnomoniella?

Re : Diaporthale on Geranium

Yes, because of a pseudoseptum on Melzer-photo, I thought at Apiognomonia too, but is it really a septum ? I don't think. Find the genus is difficult without molecular data, you know . Gnomoniella ? not impossible. I've no more knowledge than you.


Sorry,


Alain

Re : Diaporthale on Geranium
Yes. I tought this was a septum in Melzer's reagent, but since I never saw it again, I didn't think it was really a septum. Even in chlorazol black it never showed up again.
Thank you for help me, Alain.
