Small Pyreno on bark of Salix
Perz Piotr, 15-05-2007 18:25
Hi,

I found this small Pyreno on Salix bark. Asci IKI-, all parts KOH-. I don't know asci 8- or 4-spored :(
Spores 4-celled (3-septate).

Hi res platte here: http://www.mikologia.pl/rozne_pliki/20070426-007%20201.jpg

Any idea?

Hi Pimpek,
this could be a number of different things!!
First check if it is not a Chaetosphaeria, with a small refractive apical ring and tapering paraphyses, but if the anamorph is lacking on the substrate, identification to species is difficult.
Cheers,
Jacques

Re:Small Pyreno on bark of Salix
Hi Jacques,

I was thinking, that Chaetosphaeria is a single (sub)globose Perithecjum w/o stroma. And here we have a "flat" stroma with a single perithecjum inside.

Hi Pimpek,

judging from your last drawing I agree it cannot be a Chaetosphaeria. I have no better idea for the moment....
Cheers,
