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
