Hello, one more asco for today

Growing in groups/clusters on a decomposing wood of deciduous tree, possibly Prunus,
Small, not exceeding 1 mm, 0,3-0,8mm, with prominent hairy margin.

Asci: 8-spored, mostly uniseriate, some bi
Ascospores: oval 5,5-7,5?m x 1,8-2.2?m, with 2 guttules near poles
Paraphyses: straight, narrow
Hairs: hook-shaped

Apologies for bad microphotos and scarce information, i was unable get more from my microscope. I hope u´ll be able to ID atleast the genus.
Many thanks in advance.
Adam

Re : Small disco on deteriorating wood of deciduous tree
The genus is easy, Unguiculariopsis. the species very difficult.

The hairs are very typical, and the asci must be inamyloid.

Re : Small disco on deteriorating wood of deciduous tree
yes the asci are inamyloid, i forgot to add. Are there any features i could look for to bring us closer to identification?

Many thanks!

Re : Small disco on deteriorating wood of deciduous tree
This genus is not very well explored. We have lots of collections that are probably new species, but the limits are very difficult. You can try the monograph.
