Venturia on Euphorbia stems
Enrique Rubio, 30-04-2022 13:34
Enrique RubioThe setose pseudotecia of this venturiaceous fungus grew in circles around blackish spots on stems of Euphorbia hyberna at 1300 m of altitude. I cannot find any Venturia on such a substrate in the literature, except for one recently described, in its asexual morph, in Euphorbia paralias.
As you can see the spores are greenish, smooth and have a distinctly infra-medial septum.
Do you have any ideas that could help me?
