Chlamydospores of Arthrobotrys flagrans

Once a fungus spore has committed to hyphal growth and the vegetative hyphae are exploiting the substrate then a top priority is ensuring  persistence for the next generation of growth.     Producing an asexual or sexual fruitbody takes time and time may be at a premium.

The chlamydospore is a method of   producing a thick-walled resting spore very quickly.  Nutrient is shunted from adjacent cells into a preferred cell and it swells up, converts nutrient materials to oil droplets for efficient storage, then rounds off with a thick, often roughened outer wall for protection.   Chlamydospores are for persistent and are only released by death and disintegration of the originating hypha.   Chlamydospores can survive for many years under favourable conditions.
