Hi Joseba,

Surely : Chaetosphaerella. C. fusca vs C. phaeostroma, perhaps you will find the answer in Mycotaxon 70 :  387-420.

It's easier when we observe the anamorphic stage.

You show subiculum with setae, but have you seen conidias ?

Here in attached photo is Chaetosphaerella fusca = Oedemium didymum that I'm just working (what a coïncidence !)

Differences are in ascospores size, and the anamorphs are different.

You can find all informations in Mycotaxon 70.

I will send you pages uploaded at Cyberliber in your mailbox.

Here, I think the last photo shows Odemium didymum conidiophores, so it should be Chaetosphaerella fusca.

I just post my photos in Ascofrance database.
