What is the Difference Between Uredospore and Teliospore?
🆚 Go to Comparative Table 🆚Uredospore and teliospore are two types of fungal spores that play a significant role in plant diseases, specifically leaf rust and leaf smut. The key differences between uredospore and teliospore are:
- Texture of the spore cell wall: Uredospores have thin cell walls, while teliospores have thick cell walls.
- Color: Uredospores are rusty red in color, whereas teliospores are brown in color.
- Formation: Uredospores are produced by urediniomycetes during leaf rust, while teliospores are produced by both uredinomycetes and ustilaginales fungi during leaf rust and smut.
- Host dependency: Uredospores can be either heteroecious (requiring two unrelated hosts to complete its life cycle) or autoecious (all stages of the fungal life cycle occur on the same host), while teliospores are typically intercellular, using haustoria.
Both uredospores and teliospores are reproductive structures of fungi and undergo meiosis during their life cycles. However, they differ in their cell wall thickness, color, formation, and host dependency.

Comparative Table: Uredospore vs Teliospore
Uredospore and teliospore are two types of fungal spores produced by Uredinomycetes and Ustilaginales fungi, respectively, during leaf rust and smut. Here is a table comparing their key features:
Feature | Uredospore | Teliospore |
---|---|---|
Cell Wall Thickness | Thin | Thick |
Shape | Oval | Spindle-shaped |
Spore Color | Rusty red | Brown |
Position | Produced inside the uredinium or uredosorus, usually found on the underside of the leaf | Produced during leaf rust and smut |
Germination | Releases multiple spores that spread to other parts of the same plant and new hosts | Infects other plants nearby |
Both uredospores and teliospores contain two nuclei within a single cell and are seen in leaf rusts. They also have a single cell wall.
