LOPHODERMIUM ?
Alain Delannoy, 05-04-2015 09:09
Bonjour,

J'ai récolté des tiges mortes de Pivoine (Paeonia) envahies par ce champignon, y compris les feuilles.

Taille 0,4-0,7 x 0,3 mm
Asques 80-90 x 10 Microns
Spores 45-50 x 1,5 -2 Microns.

Dans ma littérature l'espèce le plus proche est Lophodermium typhinum mais le support est Typha ??

Une autre idée ?

Amitiés,

Alain LN

Re : LOPHODERMIUM ?
we have the same thing in Denmark but again with spores smaller than in the original treatment. Anybody know if this is ok? Our measurements are the same af for the material reported above.

cheers
