Hymenoscyphus caudatus??

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??

Gracias por su ayuda, Zotto.


Pongo unas fotos de esporas germinando. La mayoría germinan por un extremo, aunque he visto alguna que lo hace por los 2.


Saludos

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