can Actinoscypha muelleri be confirmed?
Lothar Krieglsteiner, 04-06-2024 17:29
Lothar Krieglsteinerfound yesterday on Carex flacca, Schwäbische Alb, Southern Germany. The spores are about (20)-22-27 (28)/5-6 (6,5) µm large and full of small guttules, and they are mostly one-celled, but some older and dead spores could be observed three-septate. The asci are iodine-positive (euamyloid, blue) and with a porus of Calycina-type, and with croziers at the base. The excipulum is of textura angularis (ca.), the marginal and lateral hairs as well as the paraphyses contain yellow vacuolar bodies.
I first thought of a Calycellina, but in Ellis & Ellis I found Actinoscypha fitting quite well. In a contribution in ascofrance I read that Pseudonaevia caricina is likely a synonym.
Who can confirm my suggestrion?
Yours, Lothar

Great collection! W. Beyer made a drawing of a fresh find with yellow VBs in hooked paraphses, just as in yours. I have the species in my folders Pezizellaceae, Micropeziza, caricina. Maybe wrongly so, who knows. Yes, Pseudonaevia caricina coud be the same (but would be a younger synonym).
