Yellow Ascomycetes on Picea cone

Thomas Flammer, 12-09-2023 09:16

On a pinus cone I found some very small round Ascos (1 mm). Elliptical spores. Spore size 3,5 x 8,5 and Ascus length of around 80 ym. The content of the paraphyses in Barals solution looks kind of banded.
8.4 - 10.8 x 3.7 - 4.6 ?m - ØQ:2.4 )
Ascus Jod negative

Re : Yellow Ascomycetes on Picea cone

Important is 1. the excipulum and 2. the contents of the living paraphyses, not the dead ones (IKI kills the cells within a short time). 3. Asci with amyloid ring?
