Teliospores are specialized spores produced by certain fungi, particularly those in the group known as Basidiomycetes. They serve as a survival mechanism, allowing the fungus to endure unfavorable environmental conditions. Teliospores are typically thick-walled and can remain dormant for extended periods until conditions become suitable for germination. When conditions improve, teliospores germinate to produce basidiospores, which are the reproductive spores of the fungus. This process is crucial for the life cycle of these fungi, enabling them to spread and colonize new environments. Teliospores play a significant role in the ecology of their habitats, contributing to nutrient cycling and ecosystem dynamics.
