Cumminsiella mirabilissima on Berberis aquifolium; uredinia

Berberis aquifolium, Amsterdam: group of uredinia, underside of the leaf

Cumminsiella mirabilissima on Berberis aquifolium single uredium

a single uredinium; between the golden urediniospores a few dark brown teliospores

Cumminsiella mirabilissima: uredinio- and teliospores

here the number of teliospores is not much lower than that of the urediniospores

Cumminsiella mirabilissima: teliospores

the teliospores have very long stalks

Cumminsiella mirabilissima: teliospore

they are two-celled and finely punctuated

Cumminsiella mirabilissima: urediniospores

the urediniospores are pear-shaped, very finely spinulose.

no host plant alternation. Spermogonia on small red spots on the upperside of the leaf. Aecia (rarely formed om the older leaves, sometimes the fruits) usually hypophyllous, on thickened, blackened areas that later may drop out of the leaf; the peridial margin is birght yellow. Urediniospores and teliospores develop in seemingly identical, hypophyllous sori, in varying proportion; often only urediniospores.

host plants

Berberidaceae, oligophagous

Berberis repens; Mahonia aquifolium, japonica.


Puccinia mirabilissima Peck, 1881; Uropyxis mirabilissima Magnus, 1892; Uroyxis sanguinea Arthur, 1907; Cumminsiella sanguinea (Peck) Arthur, 1933.


The aecia may be confused with those of Puccinia graminisl in that species the perdial margin is rather (yellowish) white (Pscheid & Ocamb).
