These are about 0,3 mm wide.

Re:Rhytismatales? on Humulus
They seem to be immature, but maybe someone has met them before.
Asci up to 150x5-6 (perhaps wider near the base) here in lugol.

Re:Rhytismatales? on Humulus
Hello,
I tried this again, still immature. But this could represent the same species as those I've found on Urtica and Epilobium.
Last year (poor microscope) theres a mention of 90-120 x1 sized spores.
Maybe a Stictis. Where can I find a key for them?

Hi Marja,

I have this in pdf format :

Mycol Res. 2006 Jul;110(Pt 7):773-89.
Stictis s. lat. (Ostropales, Ascomycota) in northern Scandinavia, with a key and notes on morphological variation in relation to lifestyle.
Wedin M, Döring H, Gilenstam G.

If you want this article by mail, let me know.

Regards,
Beñat

Hello

Oh yes, I'd love to have it. Of course I could give the local library an order for it from Helsinki University, but it would take lot of time and I'm not known of my patience ;)

My e-mail: marjamaalta@luukku.com

Greetings from Marja

Hi Beñat,

could you please send the paper to me too? My e-mail is gernot.friebes@gmx.at . Many thanks!

Marja, there is a paper by Martha Sherwood with a key and descriptions: http://www.cybertruffle.org.uk/cyberliber/59575/0005/001/0001.htm

Best wishes

Hi,

Re:Rhytismatales? on Humulus
I'm testing to get better microphotos, but things were turning worse this time.
Anyway there's a part of asci to show, that the spores are screwed inside.
The spores seem to be very narrow and long, 1,5 micrometers wide and multiseptate (about16+) 8/asci, which are 150-170x5-8.
But can the spores really be longer than asci ,as it seems or am I hallucinating?

This is something like Stictis pusilla times two ;)
