Neonectria punicea?
Mirek Gryc, 12-05-2020 13:13
Hi everyone
This spring, I found this species growing on the dead branches of Populus. I didn't see any anamorphs at first. I bred him, however, until the moment when conidia began to form on ascomat. I have no experience with them but it seems to me that Cylindrocarpon sp.
If so, then I should look for a solution like Neonectria. I am sure of the substrate, so most species that are attached to one host should be rejected.
Of the European species and growing on a different substrate basically I only have this one species ???
As usual, I could have missed something so I would ask for your opinion.

Mature spores slightly rough.
greetings
Mirek

Re : Neonectria punicea?
Hi, Mirek,
Are ascomata on a stroma?
From the photos, this species seems fungicolous. Could you make a vertical section through a perithetical stroma and wood to see if there is a fungus host?

Also, from your pictures, I'm not sure the asexual morph is a Cylindrocarpon.

Regards
Christian

Re : Neonectria punicea?
Hi Christian
I didn't answer for a long time because I wanted to prove that you are right :)
I waited for something to grow from these white hyphae.
From what looked like Cylindrocarpon, ascocarp Lachnella began to grow.

Is it a parasitic species, I can not tell. Microscopic studies do not confirm this, but macroscopically it can be seen that the fruiting bodies of Nectriaceae grow on some other medium?
Maybe they are actually rootstocks of some other mushroom?
I attach photos. You have more experience with them. Maybe you can see something in my photos, although the sporocarps are very small, and the details are not clearly visible in the pictures.
Thank you and best regards
Mirek

Re : Neonectria punicea?

Hello and welcome to all after a long time, but at the time of finding the mushrooms, I was unable to microscopy the Nectria host due to its poor condition. A few days ago I was in the same place and I took bark samples from the same substrate along with the species that was the host for Nectria.

As it is very difficult for me to identify this type of mushroom, I am asking you for help.

Spores:

(7.8) 8 - 8.6 (9) × (2) 2.1 - 2.4 (2.6) µm
Q = (3.1) 3.3 - 3.9 (4.2) ; N = 9
Me = 8.3 × 2.3 µm ; Qe = 3.6

8.24 2.25
8.25 2.10
8.08 2.45
7.78 2.23
8.56 2.30
9.02 2.33
8.41 2.44
8.55 2.03
7.96 2.56

Populus tremula

best regards
