Bernard CLESSEBonsoir à toutes et tous,Pourriez-vous m'aider à
Something Orbilia-like growing on a piece of hardwood, probably Salix, on a wet lake shore, southern Finland not far from Karsten's hunting grounds. The diameter of the apo is up to 1 mm, very light brownish, soon drying to greyish, subsessile. Asci 20-25 x 3, clavate, IKI-. Paraphyses capitate, capitulum 3 µ, at its narrowest 1,5 µ, with something on the sides of the capitulum which I interpret to be remnants of an epithecium, often with a few septa further down. Spores cylindric, very difficult to catpture on a photo, something like 1 x 4 µ, mostly they seem so have a spore body in both ends and sometimes also something in the middle.
Could this be Orbilia epipora?
Stefan
The paraphyses are covered by a thin exudate which is pushed up by the growing head. The word epithecium is often used for it, but I don't find it useful.
Typical is the gregarious growth of whitish apos in vast number.
Would you mind sending me the coordinates and collection date?
Did you check the wood anatomy to exclude e.g. Fraxinus or Fagus which are easy to recognize?

Can I speak of a log or branch, or is it a fragment hereof?
