Gnomonia on Euphorbia
Enrique Rubio, 01-07-2013 14:24
Enrique RubioHi to all

This Gnomonia grew on stems of Euphorbia sp. at 1300 m of altitude. I think is closely related with Gnomonia palustris but their spores are greater than those described in Monod's monographie.
By the other hand I don't know what species of Euphorbia is but Euphorbia palustris is not present at this region. 
The perithecia of my collection are enough extenuate  when I have studied it
Thanks again for your opinion

Re : Gnomonia on Euphorbia
Definitively Euphorbia palustris is not reported from Asturias. It seems to be that only exists at at Gerona (NE of Spain)

Re : Gnomonia on Euphorbia
Hi Enrique, 

The genus Euphorbia is not easy, and the Gnomoniaceae on Euphorbia are perhaps bad known yet.

Clearly, your species is not G. palustris and is not  described in Monod. Perhaps you should search the description of Gnomonia petrophilae ?

PS :  D. Walker is far away (Japan) this summer. We can't have his help.
