Puccinia vulpiana is a stand fungal art from the order of the rust fungi (Pucciniales). The fungus is a endoparasite of leeks and spring Schwingeln . Symptoms of infestation by the species are yellow spots of rust and pustules on the leaf surfaces of the host plants. The distribution area includes the western Mediterranean .
features
Puccinia vulpiana can only be recognized with the naked eye by means of the spore beds emerging on the surface of the host. They grow in nests that appear as yellowish to brown or blackish spots and pustules on the leaf or stem surfaces.
The mycelium of Puccinia vulpiana grows as with all Puccinia TYPES intercellular and forms Saugfäden that grow into the storage tissue of the host. The Telien the way are small, dot or line-shaped and first lead-gray, later black. The teleutospores are two-celled, elongated and 48–60 × 15–25 µm in size. They are brown, their stem is pale brown and short. Pycnias , Aecidien and Uredien have not yet been described in detail.
distribution
Puccinia vulpiana has a distribution area that extends over the western Mediterranean.
ecology
The host plants of Puccinia vulpiana are as Haplont leek ( Allium spp.) And feather fescue ( Vulpis 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 Pycnien, Uredien, Telien and Aecidien.
