Disco on Picea
Stefan Blaser, 04-07-2013 14:28
Hello everybody

Can anyone help me with this species?


Substrate: On dead, hanging Picea abies twig


Macro: Apothecia sessile, completely covered with a nearly black cuticle when young, tearing up and exposing the greyish disc. Discs mostly 2-3 mm in diam.


Micro: Asci club-shaped, 155-175 x 20-25 µm. Paraphyses cylindric, filiform, about 2 µm diam. Spores extremely thick-walled (or with a persistent slime sheath?), usually 34-45 x 10-12.5 µm. Outer shape broadly fusiform. Excipulum (cuticular layer) consisting of very strongly dark-brown pigmented, angular or rounded cells.


Thank you for any comments


Stefan

Splendid!!

Triblidiopsis pinastri (also Tryblidiopsis)

(despite the name only on Picea).

Hallo Zotto

Vielen Dank für die ultraschnelle Identifikation. Und ich habe vorher so lange rumgesucht :)
