Hello,

I am wondering whether someone could give a clue of what this nectrioid fungus is. We found it in a warm and hyperoceanic area in the Basque area on a Laurus branch. It is growing on a kind of subiculum made up of algae. I don´t have much literature at hand to identify it. Perithecia 0.2 mm in diam, dark reddish brown. Perithecial wall 18-25 µm thick, 3-4 µm. KOH=0. Spores fusiform, straight to curved, 3-septate, 23-27 x 4-4.5 µm, filled with small refringent colourless guttules. Asci 63 x 10 µm, with apical pore.

The negative KOH reaction excluded Nectriaceae, probably a Bionectriaceae, any ideas? Thank you in advance!

Ibai.
