The Pucciniaceae are a family of rust fungi (Pucciniales) that cause plant diseases . In addition to sweet grasses , which also include the different types of grain such as wheat , many other crops are also attacked by species of this family. The common names of the species therefore often contain the name of the useful plant relevant to humans. In doing so, however, the Pucciniaceae species usually also attack other related host plants and wild forms of the useful plants.

features

The ampoule-shaped spore beds ( spermogonia ) are located below the epidermis in the host tissue with a small pore, the ostiole. The Aecien are mostly like those of the genus Aecidium , rarely also like Caeoma or Uredo with or without a partition. The aecidiospores are usually warty and usually form chains. The uredia are mostly uredo - or uredostilbe - similar and usually without a partition or with laterally fused pallisade-like walls, sometimes with paraphyseal-like hyphae . The uredospores are warty or prickly, stalked, and arranged differently. The telia are normally divided into chambers without a partition, but rarely with a pallisade-like peridium or by sterile hyphae. They sometimes have paraphyses . The stalked Teliospore are formed individually and are one to two-celled, the septum is transverse or oblique. Each cell has a single germ pore and usually forms an external basidium during germination .
