                Are the spores formed inside asci?

                Dear Otto,
It's me who have to apologize, I don't have a good equipment yet. I'm going to upload all the photos that I have (zoomed), however, maybe the spores are immature and should become 2-3 septate (it's just a feeling and based on some shadows in them and on a photo where one seems to be 3-septate).
I understand you have your scientific way of thinking(and it is correct), but forget it for a while and focus on macro photos, what does it remind you?
Thanks
Elsa

                Re : On Eucalyptus globulus bark
                I actually cannot say a genus. The excipulum structure would be necessary. And the iodine reaction of the ascus apex. Also the paraphyses.
I have no Eucalyptus in my area, so I know little about fungi on such substrates.

                Thank you Otto. Photo of the excipulum wall is the 4th. I can attach a close up. About the iodine reaction it was very weak, I have to repeat it to look better, I just saw a point on the tip. Paraphyses are straight and branched, if septate (not sure) only on the base.

                Re : On Eucalyptus globulus bark
                Now it is better and we can exclude any mollisiaceoius fungus. But otherwise there are various optiions. The excipulum looks hyaline? or brownish at the base? I cannot exclude a Calycina nor a pale form of a Durella.

            Re : On Eucalyptus globulus bark
                The excipulum is all brownish darker at the base, hyphae structure. Apothecia turbinate +/- 0.08mm diam by +/- 0.6mm high, only seen with lenses.

                Re : On Eucalyptus globulus bark
                Apothecia surely  0.8 mm diam., but 0.6 mm high? The large asci and spores seem special, but I do not recall a species. Was the substrate exposed and dry or from a permanently moist place?

            Re : On Eucalyptus globulus bark
                Dear Otto,
You're right 0.6 can be enlarged by slide squeezing, forget it. The bark was taken from a normal place, I mean not always wet, but shaded, after many days of raining, maybe covered by other barks, that's difficult to say now.
I found it curious too, specialy the excipulum and big spores, that's why I upload here (a house without a roof). If closed it could be any ...sphaeria, but it isn't).
Don't worry, thanks anyway. If you remember anything... post :)
I will keep it for Björn maybe for a better microscopy, or anyone else.
Regards
Elsa
