Dasyscyphella?

Hola,
Encontrados sobre una rama de madera desconocida.
Los Apotecios estaban inmaduros y no he conseguido ver esporas ni parafisis maduras. Tan sólo un himenio inmaduro donde no parece haber croziers.
Los pelos median hasta 100um de longitud.
He pensado que podia ser Dasyscyphella crystallina. ¿Es posible?

Saludos y gracias de antemano

Susana

Hi Susana
yes, crystals and absence of croziers, also the season point to crystallina. 

The hair photo looks for me as being in water, look at the vacuoles, in KOH they would look quite different.

I saw several dozens of samples of D. crystallina, always on Quercus, except once on Castanea. Could you have a look, is the wood ring-pored?

Re : Dasyscyphella?
Ah yes, distinctly ring-pored, so it must be Quercus. I once confused Fagus with it because I did not look at the scale. Fagus has much smaller pores and is usually not ring-pored. So what is the diameter of the twig?

Re : Dasyscyphella?
La rama mide aproximadamente 1cm.

Re : Dasyscyphella?
Thanks, this is fine. So the pores have about 80-120 µm diam. which is typical of Quercus. Fagus has around 40-60(-80) µm.
