Cryptodiaporthe lirelle on Rosa ??
Jac Gelderblom, 05-04-2017 14:56
Dear friends

On thin Rosastems I found black ascomata in stromata(see pictures).
Diameter stromata up to 0,4-0,5 mm
Asci 37-39 x 6 micron, loosening
Spores 7-9 x 2,5 micron, septum nearly invisible inwater but clearly in IKI,
Except for growing on Rosa instead of Filipendula it fits very well with Cryptodiaporthe lirella.
What do you think of it?

Greetings
