Pyrenomycete ?
Garcia Susana, 29-04-2014 16:13
Hi all:

Ascomycete growing on degraded hardwood indeterminate.


Carbonaceous perithecia immersed with more or less long neck. They grow in large groups.
The data are reflected in the images. Asci seem to have a special disposition along hyphal axes. Spores are measures in asci.



I do not know what genre belong.
Can someone help me to identify it.



Thanks in advance
regards


Susana

Re : Pyrenomycete ?
Hello

I have been looking for information on the Internet, and have concluded that it may be Togninia minima.
Esporal and ascal sizes are coincident. And it have a lateral and terminal ascal disposition on ascogenas hyphae (as in a Ear of Wheat ).
You think it may be that species?

Thanks,
Susana

Re : Pyrenomycete ?
Hi Susana, Hola Susana,

Yes, beatiful photos! I love this fungus.
I studied several species during my PhD work a long time ago!

In the past it used to be the genus Erostella. There are 2 species very close : T. minima 2006 and T. minutissima (=Erostellaminutissima A. I. Romero & Samuels, Sydowia 43: 236. 1991)

I have tried to send to you tw articles through ASCOFRANCE but I could not do it.
If you write to me, I will send it my e-mail (my address is a.rome1325@gmail.com)

cariños

Re : Pyrenomycete ?
Hi Susana,

I have written you an answer before, but unfortunately it did not work (however?).

Again: this is T. minima, in my opinion. It definitely belongs to Calosphaeriaceae, but due to asci arrangement it is not Calosphaeria or Jattaea. I did not ever seen Togninia before, the species seem to be rare.

Can you please send me the photos for the page? I would like to update the Calosphaeriaceae with this new genus.

regards,
björn
