Hymenoscyphus serotinus?

Hola a todos.


Subo unas fotos de un asco que encontramos el sábado sobre madera de Fagus sylvatica.


Miden hasta 3 mm de diámetro y hasta 7 mm de altura.


Esporas de 24-29 x 4-5 micras. Subo fotos de esporas recién expulsadas del asca y de obtenidas de esporada libre al día siguiente de la recolecta.


Ascas pleurorrincas y amiloides.


Pongo fotos de células de excípulo ectal y de las hifas que se ven a modo de pruina en el exterior.


Pensé en Hymenoscyphus serotinus, ¿Qué os parece?


Gracias por sus respuestas.


Rubén

Re : Hymenoscyphus serotinus?
Why any doubts? You show very well the changes of spore guttulation between freshly ejected (taxonomically informative) and distorted after being ?rehydrated the day after.

Is this from Pyrenee? Yesterday?

Re : Hymenoscyphus serotinus?

Hola Zotto.


Gracias por su ayuda.


Es la primera vez que estudio esta especie y por eso dudaba un poco.


La recolecta está hecha en La Rioja, a unos 1400 metros de altura y sobre ramitas de Fagus y la encontramos ayer.


Saludos


Rubén

Re : Hymenoscyphus serotinus?
beautiful pictures! i've been in french vosges a few days ago and the ground in fagus-forest over 1000m altitude was full of twigs with h. serotinus! perhaps this species likes high altitude?

best

Re : Hymenoscyphus serotinus?
In the south yes. But it simply likes Fagus. In our article in ascomycete.org we have it in northern Europe at 45-800 m, central E. 220-1250 m and south E. at 550-1600 m.
