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

I agree. You should find crystals on top of warted hairs.

Hi Peter and Otto,

Thank you both. I had that feeling, but just wanted to be sure.
