A dematiaceous hyphomycete on Filipendula

Bonjour encore,
Pouvez-vous m'aider, s'il vous plait? Mais je crois que ses petis champignons sont tres difficiles! J'utilise "Microfungi on Land Plants" Ellis & Ellis (1997).
I found this dark hypho with Lachnum nudipes on dead stem remnants of Filipendula ulmaria.
It has intersting curved/coiled septate hyphae, and is accompanied by abundant hyaline conidia which are aseptate, filiform, 12-15 x 1.5 um. I used sellotape to make a mount, but couldn't see if or how the conidia were attached to the hyphae.
Scales in 10 um intervals.

Perhaps a species of Circinotrichum.

Re : A dematiaceous hyphomycete on Filipendula
Thanks for the suggestion, Adrian.
Just had a brief browse on the internet (Ellis & Ellis not much help) - the hyphae/setae are definitely circinate! the clustered simple conidia match the Circinotrichum model - stuck together in a mucoid mass - if they are produced at the base of the setae then that's why I couldn't see where they were from - my sellotape mount missed any basal hyphae. Must do a vertical CS as well with these dark Hyphos.
