Puccinia thlaspeos on Noccaea caerulescens

infected plant have a pale colour and do not come into flowering

telia at the undersides of the leaves

Puccinia thlaspeos: teliospores


Puccinia thlaspeos: germinating teliospores

the spores germinate almost immediately, forming a basidium

at low magnification the early germination is recognisable by the greyish aspect of the telia

Puccinia thlaspeos: telia and teliospores

Thlaspi stenopterum, from Unamuno (1941a): infected plant, underside of a leaf with telia, teliospores (some unicellular, other germinating)


No host plant alternation; only telia. The fungus is systemic; infected plants clearly appear diseased. The pulvinate telia, brown at first, greyish later, cover the entire underside of the leaves. Spores 12-21 x 35-55 µm, mostly two-celled, broad-elliptic, smooth, on a short, persistent pedicel, soon germinating.
