Re : Asco on silene
This is on the stem, yes? Is it an area above the timberline?
With this spore size I find only one species on Silene with such a spore size in my database, Pyrenopeziza capsulicola Petrak. The detailed but unillustrated description inludes a fungus of about 0.5 mm diam. on dead, dry capsules of Silene acaulis at an alpine site in Tirol; but the 19-26 x 5-6.5 µm large, ellipsoid-clavate-fusoid spores are said to be non-septate. Ascus reaction not stated.

Re : Asco on silene
Dear Zotto,
Thank you for the reply, hmm yes than it may be a different species, i had hard find anything possible and dident know this species you meantion.
The fungus manily grow on the top leaf and top of plant, but also steam i see.
This was above the tree line but some Sorbus was seen at the locality. But it was in a coold alpine habitat i would say and no betula was at the locality, about 450 m over sea in an mountain area.
best regards,
Robin

Re : Asco on silene
I know P. capsulicola was only briefly mentioned by Hütter 1958, so it might be it has never been reexamined or recollected. Given the same host plant I would still consider that it could be this species. Checking the type would reveal if there are really no spore septa and clarify the ascus amyloidity.
