Spores 4,9-7,0 x 1,5-2 µm, cylindriques, à deux grosses gouttes, 1-septées.
Asques 38-50 x 4,5-6 µm, bisériées, bouclées, I négatif (Melzer), 8-sp.
Paraphyses étroitement cylindriques, parfois ramifiées au sommet.
Excipulum a textura intricata. Poils externes courtement articulés, à terminaison clavée.

Re : Chlorociboria ?

I guess this is the ochraceous form of Ionomidotis fulvotingens, which Alex Akulov presented here in Nov. 2011.

When you add KOH to the fungus it should exude a striking honey-yellow sap, or turn dark red when macroscopically viewed .

Re : Chlorociboria ?

on photo 8 I see something in the backgound that might be old effete stromata of Hypoxylon rubiginosum. Is it the case?
I always find this ochreous Ionomidotis associated with the Hypoxylon. Something to corroborate with observations from other regions.
Cheers,
Jacques

Re : Chlorociboria ?

Thank you Zotto.

Yes Jacques, checked on exsciccatum : an old Hypoxylon present close to the apothecia.
