Uromyces Inayati is a stand fungal art from the order of the rust fungi (Pucciniales). The fungus is an endoparasite of the sweet grass Apluda mutica . Symptoms of the infestation by the species are rust spots and pustules on the leaf surfaces of the host plants. It is common in China and India .
features
Macroscopic features
Uromyces inayati can only be recognized by the naked eye from 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 Uromyces Inayati grows as with all Uromyces TYPES intercellular and forms Saugfäden that grow into the storage tissue of the host. The spermogonia and aecia of the species are not known. The yellow-brown uredia of the fungus grow on the underside of the host leaves. Its matt golden to light cinnamon brown uredospores are 20–24 × 18–21 µm in size, mostly spherical to broadly ellipsoidal and warty. The parts of the species growing underneath the leaves are black-brown, compact and uncovered. The chestnut-brown teliospores are unicellular, usually broadly ovate to spherical and 20–24 × 18–21 µm in size. Their stem is colorless to yellowish and up to 50 µm long.
distribution
The known distribution area of Uromyces inayati includes China and India .
ecology
The host plant of Uromyces inayati is Apluda mutica . 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 goes through a development cycle of which only Telien and Uredien and their host are known; Spermogonia and Aecien could not be assigned to her.
