on P. uncinata needles

Hola a todos.


Subo unas fotos de un asco encontrado hoy sobre agujas de P. uncinata a unos 1800 metros de altitud.


Esporas de 13-25 x 2,7-3,1 micras con 1 septo trasversal.


Ascas con esporas septadas, amiloides, pleurorrincas?


¿Qué les parece?


Gracias por sus respuestas.


Rubén

Re : on P. uncinata needles
The excipulum is of a brownish prismatica?

Strongly reminds me of Pseudohelotium pineti although the spores are wider.

The genus is in my Hyaloscyphaceae folder.

Re : on P. uncinata needles
Hello Zotto.
Thanks for your comments.
It is difficult to separate the hairs of the excuse to be able to photograph them.
I send more photos to clarify it.
I have only seen prismatic structure with brownish hyphae. I have not seen any globose cells.
I am waiting for spore print. I'll send more photos again then.
Cheers
Ruben

Re : on P. uncinata needles

Hola de nuevo.


Va foto de esporada libre.


Miden 13-25 x 2-2,5 micras.


También va un recorte donde se ve la forma de esporas de B. pineti y con 3 septos.


Saludos

Re : on P. uncinata needles
These are a bit narrower.

But did you see that Rehm (copied from Brefeld) shows Belonium pineti var. tapesioides, with spores with a tapered base?
