Development

They develop in telia (sing. telium, or teliosoruses).

Morphology

Teliospores are usually dark-coloured, and consist of two dikaryote
Dikaryon

Dikaryon is from Greek language, di meaning 2 and karyon meaning Nut , referring to the cell nucleus.The dikaryon is a nuclear feature which is unique to some fungi, in which after plasmogamy the two compatible nuclei of two cell pair off and cohabit without karyogamy within the cells of the hyphae, synchronous dividing so that...

Karyogamy

Karyogamy is the fusion of pronuclei of two cell s, as part of syngamy. It is one of the two major modes of reproduction in fungi. It is also the fusion of the pronuclei of two cells, as occurs in fertilization or true bacterial conjugation......

In biology or life science, meiosis is a process of reductional division in which the number of chromosomes per cell is halved. In animals, meiosis always results in the formation of gametes, while in other organisms it can give rise to spores....

A basidiospore is a reproductive spore produced by Basidiomycete fungi. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidium....
