Puccinia Aconiti-rubrae is a stand fungal art from the order of the rust fungi (Pucciniales). The fungus is an endoparasite of iron hats and fescue . Symptoms of infestation by the species are yellow spots of rust and pustules on the leaf surfaces of the host plants. The distribution area covers the whole of Europe.
features
Puccinia aconiti-rubrae can only be recognized with the naked eye by means of the spore beds protruding on the surface of the host. They grow in nests that appear as yellowish to brown or blackish spots and pustules on the leaf surfaces.
The mycelium of Puccinia aconite-rubrae grows as with all Puccinia TYPES intercellular and forms Saugfäden that grow into the storage tissue of the host. Your pyknia are honey-colored, spherical and grow in groups. The aecia of the species grow in mostly rounded groups. They have irregularly round aecidiospores from 20 to 28 × 17-23 µm , which are orange-yellow and warty. Uredien apparently do not exist. The parts of the species are point or line-shaped and colored first yellow, then black. The teleutospores are one to three-celled, club-shaped and 42–86 × 17–25 µm in size. They are brownish, their stem is very short.
distribution
Puccinia aconiti-rubrae has a distribution area that extends across Europe.
ecology
The host plants of Puccinia aconiti-rubrae are as Haplont iron hats ( Aconitum spp.) And fescue ( Festuca spp.) For the dikaryote . The fungus feeds on the nutrients present in the storage tissue of the plants, its spore beds later break through the leaf surface and release spores. The species has a development cycle with pycnias, uredia, telia and aecidia.
