Puccinia apludae is a stand fungal art from the order of the rust fungi (Pucciniales). The fungus is an endoparasite of Apluda mutica var. Aristata . Symptoms of the infestation by the species are rust spots and pustules on the leaf surfaces of the host plants. It is endemic to India .
features
Macroscopic features
Puccinia apludae 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 apludae grows as with all Puccinia TYPES intercellular and forms Saugfäden that grow into the storage tissue of the host. Aecia or spermogonia of the species are not known, the same applies to the uredia . Their brownish uredospores are oval to ovate, 19–26 × 15–19 µm in size and finely spiky. The parts of the species are black-brown, exposed early and compact. The hazel-brown teliospores are two-celled, usually ellipsoidal and 36–43 × 20–26 µm in size; their stalk is hyaline to light yellow and up to 80 µm long.
distribution
The known distribution area of Puccinia apludae only includes India .
ecology
The host plant of Puccinia apludae is Apluda mutica var. Aristata . 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 apparently has a development cycle of which only Telien and Uredien are known so far; Spermogonia and aecia could not be assigned to the fungus.
