Riet van OostenHello, Found by Laurens van der Linde on Rubus fr
a friend sent me these pictures of a Lasiosphaeria/Hilberina found on Betula in Bavaria.
Asci: 130 x15µm,
Ascospores: 45-53 x 4µm, brown, 3 x septate
Setae: brown, thick-walled, septate, up to 70 x 3-4µm.
Because of the shape of the ascospores we come up to Hilberina caudata.
Meanwhile I read different descriptions about this taxon. So I'm still quite unsure, if the determination can really be right.
Munk (1957) gives ascospores of 55-68 x 6 µm (to long and to broad)
But Fuckel (1870), who described the type collection, gives ascospores of 32 x 6 µm (to short and to broad).
If the Bavarian find is not H. caudata, what else could it be?
Thank you in advance,
Klaus
good night
