Helicogonium from Pyrenopeziza dilutella?
Mirek Gryc, 21-05-2021 10:23
Hello everyone
Does anyone know this species of Helicogonium.
Yesterday I found him, examining Pyrenopeziza dilutella, growing on Rubus.
All photos come from one Ascomata which was strong infected.
I found two forms:
1) growing on the exterior surface at the base ascomata

2) no amyloid asci

I'm sorry, but the free spores Helicogonium, I failed to obtain an.

greetings

Mirek

Interesting hooked structures on the exterior! I think I saw them but where?

The asci are in the hymenium. Did you measure the spores? I remember H. trabinelloides.

Spores should be 7-10 x 2.5-3 and asci should have croziers.

Hi Zotto
Yesterday I found only one Ascomatra from ASCI Helicogonium. Ascomata fragment I used to microscopy. The remaining part lost.
I keep my vivid collection, I will still study. I have not measured spores yet.
I browsed your disk yesterday. I also came to H. Trabinelloides. A very similar collection of Piotr P.
I also looked through other collections but there are only ASCI everywhere?

If I find any more infected fruit bodies, I will try to give more data.Difficult species for observation.
Thank you
Mirek

Re : Helicogonium from Pyrenopeziza dilutella?
Hi Zotto
Measurement not very precise, spores measured in asci, but they are normal.
Length slightly smaller but I suspect Ascomata too young, which is why I can not get free spores.
Asci with croziers, although it's quite hard to observe.

The type you specified could be appropriate.
An unexplained issue of the second form remains? Can they have a relationship between each other?
greetings
Mirek
