Teliospores consist of one, two or more dikaryote cells. Teliospores are often dark-coloured and thick-walled, especially in species where they overwinter (acting as chlamydospores). Two-celled teliospores formerly defined the genus Puccinia. Here the wall is particularly thick at the tip of the terminal cell which extends into a beak in some ...
In macrocyclic and demicyclic life cycles, the rust may be either host alternating (heteroecious) (i.e., the aecial stage is on one kind of plant but the telial stage on a different and unrelated plant), or single-host (i.e., the aecial and telial states on the same plant host). [3]
The characteristic part of the life-cycle of smuts is the thick-walled, often darkly pigmented, ornate, teliospore that serves to survive harsh conditions such as overwintering and also serves to help disperse the fungus as dry diaspores. The teliospores are initially dikaryotic but become diploid via karyogamy.

Entorrhizomycetes is the sole class in the phylum Entorrhizomycota, within the Fungi subkingdom Dikarya along with Basidiomycota and Ascomycota.It contains three genera and is a small group of teliosporic root parasites that form galls on plants in the Juncaceae (rush) and Cyperaceae (sedge) families.
Sporogenesis is the production of spores in biology.The term is also used to refer to the process of reproduction via spores. Reproductive spores were found to be formed in eukaryotic organisms, such as plants, algae and fungi, during their normal reproductive life cycle.
The International Botanical Congress in Melbourne in July 2011 made a change in the International Code of Nomenclature for algae, fungi, and plants and adopted the principle "one fungus, one name". [3] After 1 January 2013, one fungus can only have one name; the system of permitting separate names to be used for anamorphs then ended. [3]
Uredospores are the only infectious spores of Puccinia melanocephala. The uredospores disperse from the pustules via wind or rain onto the leaves of a new host sugarcane plant. [5] The uredospores then germinate on the sugarcane leaves, develop appresoria, and infect the new host plant via penetration of the plant's stomata. This cycle can be ...
