White hairy imperfect on Buxus
Martin Bemmann, 25-04-2010 22:28
Martin BemmannHi,

I hope someone has an idea to this one:

Two days ago I picked a tiny dead twig from a Buxus in the churchyard of St Peter in Heidelberg and wrapped it in moist kitchen tissue.
After these two days it developped some white, long haired fungi (0,1-0,3 mm).
There were a lot of spores/conidia but definetelly no asci.
The hairs are septated with lots of oildrops in the uppermost segment. (188-230x5,6-6,7 µm)
The conidia are fusiform and filled with some oildrops as well (8,4-9,9x2-3 µm).
I checked my books and files and found only hairy deuteros of black colour.

Any suggestions?

Cheers,

Martin

Hi Martin,

maybe compare to Volutella.

Best wishes,

Re:White hairy imperfect on Buxus
Bonjour Martin,
D’âpres les observations personnelle Volutella buxi est au départ de formes et de couleur blanche come sur votre photo puis en formes de minuscules flocons sétuleux blanc-rosâtre et enfin rose-saumoné couvrent entièrement la face inferieure des feuilles de Buxus et très souvent accompagnés de son téléomorphe Pseudonectria rousseliana. Si vous le souhaitez je peux vous envoyer un échantillon de ma récolte.
Amicalement
Mila

Dear Mila,

thank you very much for your offer to share your collection! First of all I am happy to have been guided to the name of this species by others, beeing no specialist at all in this field (and in most of other fields... ;-) ) Would be very nice to see the teleomoph one.
I will be very soon away on duty for 2 months. I would be happy if you could keep an exsiccatum for me.
I will send you an email when I'm back.

Best regards,

Martin
