Challenge on an old oak leaf

Elsa Sousa, 25-10-2017 22:25

Hi Guys,

Yes, it's always a challenge to identify things with my wonderful and clear micros...!
Apothecia stalked with hairs, stalk with hairs too.

Spores fusoid 1-septate:
(14.9) 16.9 - 18.2 (18.5) × 2.1 - 3 µm
Me = 17.3 × 2.3 µm
Ascospores ± 48 X 6 µm, 8-spored I think...Paraphyses branched. Hairs septate, up to 84 µm

Open your expertize eyes, and help me if you can :)

Thank you very much,
Elsa
