Blasco RafaelHola, a ver si me pueden ayudar con esta muestra, pensaba en Karstenia pero no encuentro ninguna que sea de Pinus.
Recogida en rama caida y muy degradada de Pinus sylvestris.
0,52--0,65 de diametro.
Parafisis x1,5, con el apice un poco mas grueso x2.se ve alguna parafisis suelta con el apice redondeado que llega  a 5--6. 
esporas de 9--12 x 1,5--2,4  (15x2,6).
ascas 40--52 x 5--6.
IKI  J -  fuerte reaccion en la preparacion.
Un saludo
Rafael

Hi Rafael,

this looks like Cryptodiscus pini.

Best wishes,
Gernot

Re : Karstenia posible
Yes, this is Cryptodiscus pini. A nice but rarely reported species differening from C. foveolaris in the dark margin and occurrence on conifer wood.

I assume it is montaneous, was this the case in yours?

You mean the IKi reactio is strong? It is, and when you pretreat with KOH the hymenium mst react deep blue.

Re : Karstenia posible
Gracias Gernot y zotto.
Si estan recogidos a unos 1400 m, Benasque, pirineo
En cuanto termine la muestra que estoy mirando pruebo el pretratado con KOH
Un saludo
