Bright orange stalked asco

I'm not very good at microscopy but the largest spores in a squash were about 5.3-6.7 x 2.2-2.6 mu, elliptical, hyaline, 8 per ascus. Paraphyses hyaline and of even width.
With many thanks for any help,
Carl

Re : Bright orange stalked asco
Hi Carl,
Thank you for this first post of yours on the Ascofrance forum. Feel welcome here.
Indeed an interesting species ! With apparently an Hymenoscyphus habit.
Some more information would help for a placement in a supraspecies entity, also micro pictures with a x100 magnification.
Can you picture the medulla and ectal cells ? Can you also test a iodine reaction on Ascus apex
Amitiés
Michel

Re : Bright orange stalked asco
Ben Mitchell, who was present when the fungus was found and who lives nearby, has been back to get another sample and taken some better microscope photos than I could, including one showing the ascus tip in Lugol's iodine. This has certainly made it darker but without much of a blue tinge. It has made the spores blue though.
The photos would have to be compressed in size and quality to meet the forum rules, so I've put them online at http://www.abrec.org.uk/OrangeAsco/orange-asco.htmjavascript:mctmp(0); to give best visibity of detail. Hope this is allowed.
Neither Ben nor I nor anyone else I know is very experienced in fungal microscopy!
