Where can chlamydospore be found?
Chlamydospores are characteristic of Candida albicans, C. dubliniensis and Metschnikowia species (Fig. 7.1) but are also occasionally noticed in old agar cultures of other taxa, including some Trichosporon and Cryptococcus species.
What are chlamydospores used for?
Chlamydospores fulfill a dual function in the genus Metschnikowia and germinate by budding or give rise to asci. The production of chlamydospores by C. albicans is most easily observed in slide cultures on rice agar; corn meal agar also gives good results with some strains.
Does Aspergillus have chlamydospores?

What Candida produces chlamydospores?
Chlamydospores are produced only by the two closely related species C. albicans and Candida dubliniensis, whose natural habitats are humans and warm-blooded animals, but not by other Candida species that are also found outside animal hosts.

What is the difference between chlamydospores and teliospores?
Chlamydospores are a result of asexual reproduction (in which case they are conidia called chlamydoconidia) or sexual reproduction (rare). Teliospores are special kind of chlamydospores formed by rusts and smuts .
