Hola a todos.
Subo unas fotos de un Hymenoscyphus que encontré sobre hojas de Salix.
Esporas con 1 septo central, de 17-21,5 x 5,5-6,5 micras.
Ascas amiloides, aporrincas.
Ya encontré una especie similar hace unas semanas, http://www.ascofrance.com/search_forum/45626, sobre hojas de arce, con esporas algo menores y sin septo central.
¿Les parece también Hymenoscyphus caudatus? He visto en internet citas con esporas más largas y estrechas, son tan variables?
Saludos
Rubén

Re : Hymenoscyphus caudatus??
Great pics as always!
This is extremely annoying, i never saw septate spores inside living asci in such a species. For me it still looks like H. caudatus, but I am irritated.
Collections with longer and narrower spores have often a much higher lipid content and are surely not the same, but are without a name and difficult to classify.

Re : Hymenoscyphus caudatus??
Si si, great!. But Hymenoscyphus usually gets septate during germination, and extremely rarely before spore discharge.
