Dear all,
This nectriaceous species was growing erumpent on twigs of old, but living plum tree (Prunus). Ascospores measure ca. 13 x 4-6 microns, and become warted and 1-septate at maturity. Is this sufficient for identification or does it need further studies?

Re : Yellow Nectria (aff. pallidula?)
Hi Edvin,
maybe your fungus is Bionectria. Vertical section through ascomatal wall could be very useful as well as the reaction in KOH and lactic acid. Please, check if there is an asexual state on the substrate or around the stromata, which should be clonostachys-like.
All the best,
Christian

Re : Yellow Nectria (aff. pallidula?)
Thanks, Christian. Do you mean cotton blue or plain lactic acid (which I do not have)? What to look for? Do you have a good article on Bionectria? I have limited access to literature on the internet.
Best regards,
Edvin

Re : Yellow Nectria (aff. pallidula?)
you should take a look at Schroers 2001 A Mponograph of Bionectria Studies in Mycology 46.

Re : Yellow Nectria (aff. pallidula?)
Thanks, again. I will see if I have access. I am thinking now maybe B. ochroleuca, but need to check further.
Regards,
Edvin
