Leptosphaeria doliolum?
Jenny Seawright, 07-04-2015 00:14
Jenny SeawrightOn dead herbaceous stem, probably from Urtica but possibly from a brassica - Leptosphaeria doliolum?

Small smooth pseudothecia with what appeared to be a faint ring visible on some (but not all). Spores light brown, 3-septate with the mid cells slightly swollen, 22-25 x 5 µm

With regards,
Jenny

Re : Leptosphaeria doliolum?
Hi Jenny,

I do not know which one you have there, its probably a Leptosphaeria but it can be another species. Here is an example of how L. doliolum should look like:

Re : Leptosphaeria doliolum?
Hello Bjorn,

Thank you for your reply and the linked page. This was one of several that I'd compared mine with and in the end wondered if spore size and septation might be of slightly more importantance than macro characteristics. 

I couldn't get a clear image of the pseudothecia but there were faint (but not pronounced) ridges on some which is why, considering the host, I'd thought Leptosphaeria doliolum might be a possibility.

Is it possible to suggest an alternate identification?

With regards,
Jenny
