Hello all, This was found on a dead Eupatorium stem and the closest I can come is possibly Clypeosphaeria mamillana, though in Ellis that is given for twigs of Acer, Cornus and Quercus. Perithecia initially immersed.
Spores becoming brown and faintly 3-septate, 20-24 x 6(-7) µm.Asci tips immediately blue in Lugols. (Is it correct to describe that as IKI+blue, euamyloid?) I tried adding KOH but wasn;t very successful ....
With regards,
Jenny
Hi Jenny,
Yes it is, I think.
It has already been seen on Rubus, Rosa, Lonicera... why not Eupatorium ?
