Telia of Puccinia chrysosplenii (goudveilroest) on Chrysosplenium oppositifolium (paarbladig goudveil), near Nijmegen. Have been looking for this species for some time. Glad that @NielsEimers discovered it a few weeks ago. #rustfungi #wildplantdisease

Endoconospora cerastii (I think) on Cerastium vulgare near Ede (NL). Thought for a moment that I found Phacellium alborosellum, but this looks very different under the microscope. #wildplantdisease

#Rust on wood spurge #Euphorbia amygdaloides transformed in pseudoflowers, caused by #Endophyllum euphorbiae-silvaticae, here with Mycodiplosis sp. larvae feeding on aecia (Buillon, FR). Nice specimen giving off a strong smell of mock-orange. 🤩 #Wildflowerhour #WildPlantDisease

Lots of Witches Broom in one of our tress - think it is a Horn Beam. A bit if research indicated that it might then be ascomycete fungus Taphrina carpini. The rust on Dock leaves is probably Puccinia phragmitis #WildPlantDisease #wildflowerhour
