Puccinia aegopodii is a stand fungal art from the order of the rust fungi (Pucciniales). The fungus is an endoparasite of the ground elder . Symptoms of the infestation by the species are rust spots and pustules on the leaf surfaces of the host plants. It iswidespread in the Palearctic .
features
Macroscopic features
Puccinia aegopodii 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 spots and pustules on the leaf surfaces.
Microscopic features
The mycelium of Puccinia aegopodii grows as with all Puccinia TYPES intercellular and forms Saugfäden that grow into the storage tissue of the host. Spermogonia and aecia of the species are absent. The same applies to uredia of the mushroom. Growing on both leaf surfaces of host plants Telien the type are black brown, powdery and soon uncovered. They are mainly on leaf veins and stems. The chocolate-brown teliospores are two-celled, usually oblong to ovate, smooth and 28–48 × 15–22 µm in size. Their stem is colorless and up to 32 µm long.
distribution
The known distribution area of Puccinia aegopodii includes all of Eurasia .
ecology
The host plant of Puccinia aegopodii is the ground elder ( Aegopodium podagraria ). 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 microcyclic development cycle that includes only Telia and does not include Aecia, Spermogonia and Uredia.
