found today on decorticated fine woody debris of Fagus, initial stage of decomposition.
Spores are cylindrical to allantoid, (22)25 – 26 µm x 5-6,5 µm, with two or four big oil drops. Often there are a lot of smaller oil drops inside. Maybe it's a young collection?
IKI and KOH + IKI negative.
Has anyone an idea where I can find?
thank you and best regards,
Regina

Hallo Andreas,
passt recht gut! Mich haben die Öltropfen ein wenig gestört, aber die Dokumentation (illustrations) in http://www.ascofrance.com/forum/14136/zignoella-ovoidea geben meinen Fund gut wieder.
Vielen Dank!
Regina
