Cryptosporella suffusa?
Björn Wergen,

a few days ago I found a small pyrenomycete on dead Alnus twigs with the following features:
Ascomata is an erumpent stroma 2-7 mm in diametre, growing in the cortex and containing 4-8 perithecia with small necks.
Spores 20-40x4-5µm, mostly smaller ones (21-24,5x4-5µm) but also some in longer size (35-40µm long), hyaline, smooth, without septa, but containing some small vakuoles.
Asci 80-90x13-17µm, with 8 spores, filled with many oil drops or something, so that the spores aren't countable in most cases, short stalked and clavate, sometimes with a roundish "swelling" on one side (?).
Can someone help me with determination? I just found something about Cryptosporella suffusa but it is not really enough. I first thought about Eutypella alnifraga but that was a no way after the first look through the micro :D

Kazuya

Re:Cryptosporella suffusa?
Hi Kazama,
Perhaps an immature C. suffusa ? Ascospores of suffusa should be longer.
Could you describe how ascospores are arranged in ascus ?
I'll send you documentation to help you.

Re:Cryptosporella suffusa?
Hi Alain,
in the Ascus, the spores are arranged in 2-3 lines, and sometimes evokate the swelling (?). As I said, the spores aren't visible in most cases due to many oil drops.
thanks for your help ;)

Re:Cryptosporella suffusa?
hi
I looked at the spores again and they are 40-80x4-5µm. I think this is enough for C. suffusa ;)

Hi Kazama,
it's now OK for C. suffusa.

Hi Kazama,
Have you read Luis Meija's paper posted by Amy Rossman ?
Particularly the difference between Cryptosporella suffusa and C. multicontinentalis should interest you.

Yes, thank you, I have checked it out and added it to my database.
