Puccinia Pulsatillae is a stand fungal art from the order of the rust fungi (Pucciniales). The fungus is an endoparasite of anemones . 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 pulsatillae 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 Pulsatillae grows as with all Puccinia TYPES intercellular and forms Saugfäden that grow into the storage tissue of the host. The parts of the species are small, rounded and connected to larger groups, about 3–4 cm in diameter. They are gray-brown in color. The teleutospores are variable, mostly club-shaped, two-celled and 50–70 × 13–21 µm in size. They are colorless to brownish, their stem is very short. Pycnien , Uredien and Aecien are not trained.
distribution
Puccinia pulsatillae has a distribution area that extends across Europe.
ecology
The host plants of Puccinia Pulsatillae are different types of anemones ( Anemone spp.) And cowbells ( Pulsatilla spp.). In Austria it occurs on the large windflower and alpine pasque flower . 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 that shows only parts and does not need to change hosts.
