Dermea padi?

Hello forum,this week I found this Dermea on bark of Prunus padus trunk (partly broken but still alive). This one has rather different spores from D. prunastri, but I didn't find any illustration of spores of D. padi in my literature. Nauta & Spooner (2000) give spore length as 15-20 um for D. padi - is that real size, or maybe a result of mixed literary data? (Zotto wrote here earlier, that the concepts of D. padi and D. prunastri might be interchanged in some works.) Can I call it D. padi or another name?
Thank you in advance for any advice.
Viktorie

Re : Dermea padi?
Hi Viktorie
This is actually what I call D. padi. D. prunastri on Prunus spinosa has narrower, always distinctly curved conidia.
Conidial width varies between *3.5-4 and *4.5-5 µm among my pics, and yours are with 3-3.5 at the very low end.
Yes it is with croziers.
