Hello everyone,recently I found a large growing place of Ficaria verna subsp on the edge of a Flemish polder forest.
In search of the rust Uromyces dactylidis, which I also found, I discovered on the leaves several concentric growing clusters of yellow-orange structures that I thought were undeveloped aecia.
Under the microscope, the structures were found to be filled with conidia (?) and numerous conidiospores (?) were swimming in the reagent liquid.
I also noticed the pointed, paraphysis-like structures.
I don't find any leads in Ellis & Ellis.
Does this anamorph (?) ring a bell for someone?
Greetings, William

Re : Anamorph (??) on Ficaria verna
Hi WIlliam,
macrroscopically this looks like spermogonia of a rust fungus. So if you found aecia of U. dactylidis/poae on the same leave,this most likely are the associated spermogonia, though there are two other Uromyces species on Ficaria that could of course have infected the same plant.

Re : Anamorph (??) on Ficaria verna
Thx for your suggestion, Björn.
Perhaps this also could be an Entyloma sp?

Re : Anamorph (??) on Ficaria verna
Entlyoma ficariae looks different. Macroscopically, it produces white leaf spots, sometimes covered with the corresponding anamorph. The conidia of the anamorph are lanceolate. Teliospores of the rust which are inside the leaf are thickwalled, hyaline and more or less round.

Re : Anamorph (??) on Ficaria verna
Indeed Björn is quite correct on both counts - here is a composite of the Entyloma
regards, Chris
* and I do appreciate we are not dealing with ascomycetes here, but people could possibly confuse the conidial phase of the Entyloma with a Ramularia
