Teliospore (sometimes called teleutospore) is the thick-walled resting spore of some fungi (rusts and smuts), from which the basidium arises. Development [ edit ]
An iron- and phosphorus-rich neck band bridges the plant and fungal membranes in the space between the cells for water flow, known as the apoplast, thus preventing the nutrients reaching the plant's cells.

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.
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.
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 ...
Bauer et al. speculated that the teliospore tetrad in entorrhizomycetes might represent the ancestral state of dikaryan meiosporangia. This is based on the observation that the septa in the tetrads have pores, and that the tetrad compartments germinate into hyphae terminating in propagules.
The separate names for anamorphs of fungi with a pleomorphic life-cycle has been an issue of debate since the phenomenon was recognized in the mid-19th century. [3] This was even before the first international rules for botanical nomenclature were issued in 1867. [3]
