The #rust on #Sporobolus indicus caused by #Uromyces tenuicutis appears to overwinter well in the same location just across from dad's house, this time with #Eudarluca caricis 🤗 strongly parasitizing the old uredinia (Villeneuve-Tolosane, FR).

At the same site as last June, #rust on slender rush (#Juncus tenuis) caused by #Uromyces sp., this time showing telia & teliospores, which suggest it is U. silphii (and not U. junci as initially thought). Still parasitized by #Eudarluca caricis (Les Clayes-sous-Bois, France).

#Rust of erect brome (#Bromus erectus) caused by #Puccinia coronata, here with uredinia and telia parasited by #Eudarluca caricis (Thiverval-Grignon, FR).

(2/2) And the same rust species on slender rush (#Juncus tenuis), here parasitized by #Eudarluca caricis.

(3/3) Even so, the attack was likely diminished by the hyperparasite #Eudarluca caricis, widespread in the older uredinia.

#Rust of wood false brome (#Brachypodium sylvaticum) caused by #Puccinia brachypodii, here with its mycoparasite #Eudarluca caricis (syn. Sphaerellopsis filum) and larvae of the mycophagous genus #Mycodiplosis (La Roche-Guyon, FR).

#Rust on #Galium lucidum caused by #Puccinia punctata, here with a mix of uredinia and telia hyperparazited with #Eudarluca caricis displaying a mass of conidia extruded as white threads (Millau, FR).

#Rust of southern wood-rush (#Luzula forsteri) caused by #Puccinia obscura, here with hypophyllous uredinia parazited by #Eudarluca caricis (Les Clayes-sous-Bois, FR).

#Rust of bushgrass (#Calamagrostis epigejos) caused by #Puccinia sp. — maybe P. pygmaea — here with uredina & urediniospores parazited by #Eudarluca caricis (Les Mureaux, FR).
