upperside of a leaf with aecia
Berberis aquifolium, Amsterdam: group of uredinia, underside of the leaf
a single uredinium; between the golden urediniospores a few dark brown teliospores
here the number of teliospores is not much lower than that of the urediniospores
the teliospores have very long stalks
they are two-celled and finely punctuated
the urediniospores are pear-shaped, very finely spinulose.
Berberis aquifolium, Belgium, prov. Antwerp, Meerhout © Carina Van Steenwinkel: a teliospore amidst urediniospores
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.
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).
