Spores fusoid 2-3 gutullate
(22.3) 23.7 - 29.4 (33.2) × (5.1) 5.6 - 7.1 (7.6) µm
Q = (3.3) 3.9 - 4.9 (5.2) ; N = 20
Me = 27 × 6.3 µm ; Qe = 4.3
Genera?
Thanks

Re : On Eucalyptus globulus bark
Are the spores formed inside asci?

Hi Otto,
Yes, I saw them protruding from the tip.
Thanks

Re : On Eucalyptus globulus bark
Sorry, but the photos are much too bad.

Re : On Eucalyptus globulus bark
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.

Re : On Eucalyptus globulus bark
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.
Hans-Otto Baral,

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
