I found nice ascomycete (max around 1 mm) on decaiyng hardwood (Ace pseudoplatanus, Carpinus betulus and Populus cf. nigra around the place of the find).
Spores nonseptate, 6.0 - 8.0 × 2.1 - 2.9 µm (N = 40), asci amyloid 37 - 45 × 3.6 - 5.0 µm, with croziers, paraphyses more or less lanceolate exceeding asci by 7 - 11 µm, 2.0 - 2.7 µm wide. Hairs septate, light brown to almost hyaline upwards, slightly encrusted, multiseptate, 3 - 4.5 µm wide.
Is it Neodasyscypha cerina???

Re : Neodasyscypha cerina?
Definitely not. This looks like my new species Lasiobelonium populi, still undescriped. it would be
good to clarify the host genus by wood anatomy.
I would be glad to receive the collection data from you.

Re : Neodasyscypha cerina?
Thank you very much, Zotto. Here are informations about find.
Date: 22.4.2018
State: Czech republic
Place: south Moravia, near Zdanice (49.07895N, 17.00599E, altitude 240 m)
Locality: humid locality about a almost dry stream
Vegetation: deciduous forest (Acer pseudoplatanus, Salix alba, Fraxinus excelsior, Populus cf. nigra, Alnus glutinosa, Tilia sp., Carpinus betulus, Prunus spinosa, Sambucus nigra, Corylus avellana), around the place of the find only Acer pseudoplatanus, Populus cf. nigra, Carpinus betulus.
Here are some additional photos from stereomicroscope (magnification 20x).
I will microscopy wood on the weekend and I will write you.

Re : Neodasyscypha cerina?
Many thanks! The substrate is a log or a thin branch? Looks decorticated.

Re : Neodasyscypha cerina?
Zotto, I could not determine wood. My experience with microscopic determining of wood are still small and wood is in advanced decay.
A piece of wood with fungus lay on the ground in "wood pulp". Obviously he came from a bigger branch.
But I can send you an exssicate.

Re : Neodasyscypha cerina?
Dear Roman
yesterday your sample arrived. I confirm Populus and L. populi.
If you give me your email address I will send you my images.
What do you remember, was it a lying trunk with maybe 10 or more cm diameter? The moss on it might be Hypnum.

Re : Neodasyscypha cerina?
Zotto, thank you for determination. The lying branch was rather disintegrating, but it was definitely thicker than 5 cm, but I do not know if it was thicker than 10 cm.
Upon another visit to the site I will look again at this fungus, but here is a great drought :-(
