Small spored Nectria
Marja Pennanen, 14-04-2014 20:54
Hello,

I am going through my old collections. I was going to throw this away as N. cinnabarina, but something seemed not so obvious.
So I studied it.
The substrate may be an apple tree.
These are about 0,2 mm wide.
The spores are with one septum, hyaline, 8-10x3-4.
The asci are about 60-80x6.

I ended to Nectria vulpina, evenif I can not see the spore ornamentation (because of being able to use only 500x magnification).
I found no photos of this species in the internet. Can this be N. vulpina or is it something else?

Re : Small spored Nectria
Hello Marja,
your specimen is not "Nectria" vulpina, it is a species remaining to the complex "Cosmospora".
There are several genera that match your collection. These species accuring on numerous Pyrenomycete hosts.
Do you know the host of your specimen ?

Regards,
Christian

Re : Small spored Nectria
Dear Christian,

I have no idea. The host is covered with these.
There is something growing near, but they are in poor condition.
Here is a photo of them.

Oh yes, when you seek for trouble, it comes to you. Maybe I should have abandoned this one ;)

I went and studied some branches of Malus near my home. There were loads of Tympanis growing on them. So Tympanis is my wild guess of the host.

Re : Small spored Nectria
Today we went to the place, where I found these. Tympanis was growing on the branches still attached to the apple tree with same kind of openings on the bark than on those on the ground. Many openings on the branches on the ground were covered with these red ones, but black host tissue was showing in some.

So, now I'm pretty sure, that these really grow on the remnants of Tympanis.
Does this help?
