Hola a todos.
Subo unas fotos de una Rutstroemia? que encontré ayer sobre ramitas sin identificar, en bosque mixto de F sylvatica-Q pyrenaica, entre otros.
Esporas de 20-23 x 5,3-6,2 micras.
Ascas amiloides, pleurorrincas.
¿Qué les parece?
Gracias por su ayuda.

Quercus and Fagus you should be able to distinguish with the wood pores (ring-pored or not). Did you look at a broken twig?

The strange thing is that R. firma usually has curved spores, but I saw also populations with straight spores. These here are completely straight. I wonder if this is all the same.
R. firma was also mixed with R. alnobetulae in earlier times, who knows how many taxa exist.
I suspect that DNA would help....

Gracias por su ayuda, Zotto, Martin.
Subo unas fotos del palito donde las encontré. Mide 5 mm de diámetro. No tengo claro que sea de Quercus o Fagus.
La dejo de momento como R firma.
Saludos
Rubén
