Hello everyone
They grow on dead branch of Prunus padus.
Due to the fact that in recent times, including the type, there has been a lot of changes, I would like to ask whether these features fit Leucostoma niveum?
Spores:
(13.1) 13.2 - 15.3 (15.4) × (2.6) 2.62 - 3.1 µm

Re : Leucoscypha niveum?
Looks like Poronia, but Leucostoma/ Valsa are probably.

Re : Leucoscypha niveum?
The spores in Boudier's concept of L. niveum are eliptical with two large droplets. See plate 346. Leucoscypha leucotricha in Icones. According to Species fungorum that is synonymous with L. niveum.

Re : Leucoscypha niveum?
Hi Mirek,
This fungus is Leucostoma auerswaldii. Nice ascostromata typical of that fungus.
You can also see asexual morph on your first picture, on the right - a conidioma with dark orange drop of conidia (Cytospora personata).

Re : Leucostoma niveum?
Thank you all for participating in the discussion!
Looking for the name for your collection, I took into account: L. niveum, L. auerswaldi and L. personnii. I compared the size of spores for these species, using various sources. However, due to the huge discrepancies, I totally lost myself.

Using your kindness if I could still ask: what should be the appropriate size range for the spores of L. auerswaldii. I'm asking because I found online collections so marked but about a slightly smaller spores and that's why I rejected this species?
Once again, thank you and best regards.

Sorry for the mistake in the name ... I have already improved!
