      Growing on the anthers of a cultivated species: Saponaria x olivana.

      Spores purplish-brown, almost globose (Q = 1.1) 6.3–8.2 µm

      It would seem to be rare in the wild. I’ve not be able to ascertain its status on cultivated species.

      Regards,

      Chris

        Interesting – a smut I’ve never seen. Round here when one sees Saponaria officinalis, either in gardens or as an escape on “waste” ground, it’s more often the “flore pleno” double form. So fewer or no anthers . . . . also while the normal form is apparently nectar-rich (and therefore attracting insect vectors) the double form has very little nectar. All a bit circumstantial but there you go.
