chlamydospora

Chlamydospora are thick-walled, asexual spores produced by certain fungi. They are typically formed within the hyphae of the parent fungus, often by the modification of a single vegetative cell or a short series of cells. These spores are characterized by their robust cell walls, which provide resistance to unfavorable environmental conditions such as desiccation, extreme temperatures, and chemical agents. This resistance allows chlamydospores to survive for extended periods, acting as a survival structure for the fungus.

The formation of chlamydospores is often triggered by environmental stress, serving as a mechanism for the fungus to persist until conditions become more favorable for growth and reproduction. Once the environment improves, the chlamydospore can germinate and develop into a new fungal colony. They are common in a variety of fungal groups, including some plant pathogens, where their survival ability contributes to the longevity of the disease cycle. The structure and method of chlamydospore formation can vary between different fungal species, aiding in their identification.
