Smut on Goat's-beard

Observation - Smut on Goat's-beard - UK and Ireland. Description: Not exactly an anther smut, but a variation upon the same theme, whereby the entire Tragopogon prate

Not exactly an anther smut, but a variation upon the same theme, whereby the entire Tragopogon pratensis flowerbud fails to develop and insteads disintegrates in a mass of chocolate brown spores. I saw Goat's-beard dotted here and there in several locations on a walk today but only this one plant was infected with the fungal pathogen. Every bud was affected.
