In a dune grassland in Oostduinkerke (Belgium), on
I found the following small black Asco, about 300 to 700ym in size, on a beech branch about 30mm thick without bark. At a height of about 2m on the trunk.
At first I thought again of a lichenized Asco, but with negative Lugol reaction of the Asci I am unsure.
Asci with hook.
Hardly any free spores found.
Spores around 30 x 5 ym
Where can I look further or who knows the species?
Many thanks for your support and opinions
Best regards
Dirk
surely more competent people will still answer you. My suggestion would be the genus Durella. With the old key of Zotto I come to D. connivens. Your collection seems to be not fully ripe - couldn`t you observe more free spores, and see if they are septate (in the picture it loosk as if they were already in the ascus ..?). The excipulum looks Durella-like to me.
Yours, Lohtar
Thank you very much for your quick reply.
The genus and species you suggested fit quite well.
I compared my photos with Zotto's photos in his "Durella folder".
D. connivens is already a good match.
I still have the branch and am trying to find free septate spores.
It will probably take a while yet.
update, the spores are still not quite ripe but you can already see between 5 and 7 septa. The spore dimensions have also changed. approx. 43-48 x 4.8-6.3 ym.
Best regards
Dirk
