Dothideomycetes sur Eryngium campestre
Bernard CLESSE, 29-03-2022 21:40
Bernard CLESSEBonsoir à toutes et tous,

J'ai trouvé récemment ce Dothideomycetes sur panicaut champêtre (Eryngium campestre). Comme cette plante-hôte est très rare dans ma région, l'ascomycète l'est probablement aussi…… :o)

Merci d'avance pour votre aide !

Bernard

Hi Bernard,

the microscopic details remind me of Hymenopsis typhae which occurs on Typha. I have no idea if it can also grow on Eryngium though.

Best,

Björn

PS: In summer time, it is also worth to look for little brown leaf spots on Eryngium caused by the smut fungus Entyloma eryngii. Not an ascomycete, but still a nice fungus.

Hi Björn,

Many thanks for your very quick response!


On https://fungi.myspecies.info/all-fungi/hymenopsis-typhae
I see that the conidia of Hymenopsis typhae are a little larger than for my harvest but actually it looks very much like it!

Best regards,

Bernard
