Puccinia schedonnardii
Puccinia schedonnardi is a Ständerpilzart from the order of rust fungi ( Pucciniales ). The fungus is an endoparasite of mallow and various grasses. Symptoms of infestation by the way are rust spots and pustules on the leaf surfaces of host plants. It is used in America and East Asia.
Features
Macroscopic characteristics
Puccinia schedonnardi with the naked eye can be seen only on the basis of the projected on the surface of the host spore deposits. They grow in clusters that appear as yellowish to brown spots and pustules on the leaf surfaces.
Microscopic characteristics
The mycelium of Puccinia schedonnardi grows intercellular as with all Puccinia species and forms Saugfäden that grow in the storage tissues of the host. The systemic growth of the fungus have Aecien 20-24 × 16-19 microns wide, ellipsoidal to spherical, hyaline Aeciosporen with wrinkled surface. The zimtbraunen uredia kind of grow on both sides of the leaves of the host plant. Your bright zimtbraunen uredospores are 21-26 × 18-24 microns in size and finely stachelwarzig. The expanding mutual Telien the type are blackish, powdery and early open lying. The bright hazel teliospores of the fungus are two-celled, rarely vertically septate, usually langellipsoid to ellipsoid and 28-26 × 18-25 microns in size. Your handle is usually colorless and up to 125 microns long.
Dissemination
The known distribution area of Puccinia schedonnardi ranges from Argentina to the northern United States and also includes Japan and the Philippines.
Ecology
The host plants of Puccinia schedonnardi are for the haploid especially Hibiscus species and other (Malvaceae spp. ) And Süßgräserd he genera Lycurus, Melica, Muhlenbergia, Schedonnardus, Sporobolus and Diplasis for the dikaryotic. The fungus feeds on the present in storage tissues of the plant nutrients, its spores bearing later break through the leaf surface, and put spores free. The type has a development cycle with Telien, uredia, spermogonia and Aecien and does a landlord change through.
