Nectriaceae or Bionectriaceae on Salix
Nick Aplin, 08-02-2015 17:55

Salut à tous,


I must admit that I'm quite out of depth with this Nectrioid species that I found on blackened Salix wood (I assume there is some other fungus present) in the South of England 6/2/2015


51.124°N 0.1418°W, 81 metres above sea level


Ascospores 7 - 9.4 x 3 - 4.1, subtly striated, live spores with ~2 guttules


Ascocarp wall 31-55 µm thick, KOH-


No anamorph seen


Without culture, I'm certainly not expecting a name for this collection, but I know there are a few regular visitors here that are interested in these species and might be able to help.


I have a dried collection of about 30 perithecia.


Amitiés,

Hi Nick,


A very very interesting species ! Excellent photos.


It should be a Nectria s.l. But  perhaphs an unknown one.


Let's wait specialists.

Hi Nick,
Interesting specimen, you should sheck if there are numerous orange  oily droplets in ascomatal wall and hymenium, by crushing (in water) a perithecium  under a cover slide.

Regards,
Christian

Re : Nectriaceae or Bionectriaceae on Salix

Salut Alain et Christian,


The first photo is of the bottom of the hymenium


The second is the top of the perithecium wall, near the ostiole


Nice orange droplets!


 


Thanks for your help,


Nick

Ok Nick,
I think your specimen remains in the Hydropisphaera "peziza" complex.
Could you check the size of ascospores?

Rien de tel qu'un vieux renard expérimenté !


Je n'avais pas reconnu Hydropisphaera peziza s.l. . Mais avec KOH-, spores striées, j'aurais dû y penser.
