I found these pycnidia growing on Hedera helix.
Since two types of conidia appear, I think it's Phomopsis , but I do not know if anyone is able to determine the species.
Alpha conida: 7-10 x 4.5-6um
Beta conidia: 16-23 x 2.5-3um
regards
Susana

Re : Phomopsis sp?
Thanks, Martin
But alpha conidia are wider.

Re : Phomopsis sp?
Furthermore Traverso describes long beaks of the pycinidia ("lunghi rostelli"), a feature not mentioned by Groves.
