unknown Nectria / Hypocreales

Björn WergenHi there,

I have a collection of what I guess belongs to Hypocreales, growing on dead stems of Colutea arborescens and I definitiely need your opinion, because I do not know what this is.

HYPOCREALES

Ascomata are pustulate, really looking like a Hypocrea, with embedded orange to orange-yellow perithecia into a white/creme stroma, which is up to 2,5mm broad.
Spores 14-17,5x4,5-5,5µm, hyaline, smooth, with a central septation and several small droplets. Asci 60-85x10-13µm, short stipitate, tips without any structures. Wall about 20-30µm, consisting of flattened, pale yellow cells, not reacting in KOH (3%, 20%).
On Colutea arborescens branch, A-1100 Vienna (Unterlaa), leg. R. Moosbeckhofer.

Any ideas?

regards,
björn

Re : unknown Nectria / Hypocreales
Hi Björn,

that's a funny coincidence because on Saturday I've collected a fungus which is presumably the same species and I wanted to show it here today. :-) 

Unfortunately I don't know the host of my collection since there was no similar plant near the place where I found the branch (Burgenland, in the east of Austria). Eutypella leprosa grows on the same branch. I attach a file with photos and descriptions. Maybe someone can help us with this enigmatic species!

Best wishes,
Gernot

Re : unknown Nectria / Hypocreales
Dear friends,
I think this fungus could be Stromatonectria caraganae (Höhn.) Jakcitsch & Voglmayr
Mycologia 103 (2) p. 435.

Best wishes,
Christian

Re : unknown Nectria / Hypocreales
Hi Christian,

thanks a lot! Now I remember that I've read that article by Jaklitsch & Voglmayr before but I didn't recall it. "Stromatonectria" is a fitting name indeed!

Best wishes,
Gernot

Re : unknown Nectria / Hypocreales
Hi Christian,

thanks for your help, its indeed the Stromatonectria caraganae, from the original place where Jaklitsch had also found it. I did not know it because I did not have this Mycologia issue on my PC (I have now).

regards,
björn
