Possibly Saccothecium sepincola?
Jenny Seawright, 02-03-2015 21:08
Jenny SeawrightHello all,

This asco was found on old, thick stems of Rubus (or possibly Rosa).

I've found nothing that fits in Ellis & Ellis 'Microfungi on Land Plants' for Rubus but I wondered if Saccothecium sepincola (given on Rosa) might be a possibility?

The spores were 3-septate, 15-17 x 6-7 µm and most asci appeared biseriate.

Once again guidance much appreciated!

With regards,
Jenny

Re : Possibly Saccothecium sepincola?
Hi Jenny
I can't for the moment suggest what your fungus is, but it certainly isn't Saccothecium sepincola. That fungus is gregarious; and the asci are ventricose, thickened at the apex, and they are seated in a bundle upon a basal cushion of small brown cells, the ascospores generally having 5 transverse septa, occasionally with a longitudinal septum as well.

best wishes
Chris

Thanks for the correction Chris, I've been trying to figure this one for hours and was clutching at straws by that point.......!
