Hello,Yesterday I found these on burnt soil. Apoth
Salut à tous,
I found this inconspicous Orbilia on Malus x scheideckeri in the South of England that I'd like some help with. The branch was dead, still attached and 6 ft from the ground.
51.093°N 0.1787°W, 96m above sea level
Unfortunately I have no material left, but I visit the site often so I have a fair chance of recollection.
Apothecia to about 0.8mm
Ascospores 4.2 - 5 x 2 - 2.6, smooth, C-shaped, with a large tearshaped-globose SB and sometimes a few smaller ones.
Although easy to see, I found the spores almost impossible to photograph - I hope they can be seen on the composite image, but if not I can provide a crop or illustration....
I've used one of Zotto's old keys, which leads me to O.vibrioides (I think! - I don't have much experience using keys to Orbilia). The spore size matches well but I can't find any further information on this species. Have I got it right?
Amitiés,
Nick
You are right I would say, it maches my collection from Germany quite well, but perhaps Zotto has another idea. It is indeed difficult to make photos of the spores.
As the species is still unpublished, it is difficult to find further information.
cheers,
Stip
It is quite normal that this species occurs only by 2-5 apothecia. It is among those that urgently need sequencing, but all more recent samples were such sparse. So if you find more, think about sending them (I sggest to Guy Marson).
Stip's collectionj is especially strange because the species is mainly submediterranean to atlantic.
Zotto
Thanks Stip & Zotto,
Yes, please do incude my collection. The branch was indeed decorticated and was 45mm diam.
The collection date was 17/1/2015 .
Has it been reported from Britain previously?
If I manage to recollect I'll be in touch.

Zotto
as far as I know only three collections from Wales.
