Sulfur yellow tiny asco on hardwood
Francois Guay, 23-06-2025 04:03
Francois GuayHi, I found this tiny sulfur yellow asco growing on a decaying hardwood log. 
-Apothecia 1-2 mm
- Spores 9,1-15 × 2,1-2,6 ?m, one or two celled
- Asci IKI +

Here is the iNat link for photos: https://www.inaturalist.ca/observations/290213767

Does anyone know what it is? Thanks

Re : Sulfur yellow tiny asco on hardwood
Looks much like a Dasyscyphella. I compared D. chrysotexta from Croatia, previously described in a new genus Velebitea. See my folder in Lachnaceae.

This would be interesting to compare also by DNA.

Awesome, thank you Zotto, I will send it to sequencing!

Forgot to say that the spores seem to get septate only after discharge, in case you want to see a difference to chrysotexta. Both your images and the protologue are in the chrysotexta-folder.
