Rutstroemia firma?

Hola a todos.


Pongo unas fotos de un asco que hemos encontrado hoy sobre madera casi seguro de Quercus.


Miden hasta 12 mm de diámetro.


Esporas de 17,5-20 x 5,5-6,3 micras.


Ascas amiloides, pleurorrincas.


Paráfisis con contenido interior de color pardo.


Pensé en Rutstroemia firma, ¿Qué les parece?


Gracias por su ayuda.


Rubén

Hello Ruben,
that's for me Rutstroemia firma too. In our distrikt not rare on Quercus, 1x Alnus twigs, mostly late in the year.
Greetings Peter.

Re : Rutstroemia firma?
yes, but I am still not sure if such straight-spored R. firma is the same as that with curved spores.

On Alnus I believe that it was another species, perhaps R. alno-betulae.
