Arachnopeziza sp.

Francois Guay, 26-04-2025 19:32

I found these small Arachnopeziza sp. growing on decorticated wood in Québec, Canada. They look similar to A. obtusipila, but the spores seem smaller and have 0 to 1 septum.

-Growing on decaying, decorticated deciduous wood

-Spores 1–2-celled, 15.77–21.02 × 2.96–3.7 µm

-Asci 8-spored, IKI+

Any idea what species it could be?

Thank you!

Re : Arachnopeziza sp.

Hi,

Spores are maybe a bit longish, but how about A. leonina? ..sometimes it's white/hyaline like this.
