Neodasyscypha cerina?
Manak Roman, 25-04-2018 21:03
Hello,
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?
Many thanks! The substrate is a log or a thin branch? Looks decorticated.
Manak Roman, 28-04-2018 20:01
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.

Thanks a lot!

Zotto, I sent the sample today. Here are all of my microscopic pictures from fresh apothecia in full resolution: http://mykologie.eu/download/lapo/lapo.html

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.

Manak Roman, 07-05-2018 20:34
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 :-(
