Diatrypella sp.; feb 2022

Hello,
Looking for opinions on this "Diatrypella"; could this be D. placenta?

Collected in February, most probably on an Alnus twig (all standing trees were Alnus)

Spores measurement: 3,9-4,5 x 0,9-1,5 µm

but IKI reaction is negative (there's a possibility that lugol's lost its strenght).

Please see attached file.

Thank you

Oui, je pense qu'il s'agit bien de Diatrypella placenta.
