Rhytismatales on Picea
Marja Pennanen, 08-04-2010 12:29
Hello

I though I was picking some Tympanis and put the specimen aside in a plastic bag and forgot it there for a week. Now when I had time I decided to try to determine it. I got supriced, because it had opened and looked like Coccomyces. It wasn't and seems to represent a genus unfamiliar to me.

The spores seems to have or not to have a cover and are about 25-35x 10-15 with cover and about 25x3-8 without. Asci about 150-250x20-25 micrometers.

The fruitbodies are 1-2 mm wide.

Re:Rhytismatales on Picea
The round spores are from myxomycetes. I have added them into water for measuring. Lacking micrometer ;)

Cher Collègue,

Il s'agit bien, comme l'indique Ernestas, de Tryblidiopsis pinastri (Pers.: Fr.) Karsten

Bonjour René,
votre image ne passe pas, trop lourde ou trop grande.
Essayez de la mettre dans la rubrique "Document" ci-dessous en format PDF.
Si ça ne fonctionne pas, envoyez-moi votre image et je la mettrai en ligne.
Cordialement,
Christian.
